What Is Dengue Fever Exactly?

Dengue Fever is no joke. It is unforgiving, life-threatening (it has already killed thousands), and most of the times all it takes is a single bite from the right mosquito.

A single bite. And the right mosquito in question is the Aedes (Stegomyia) aegypti found in most tropical countries such as India, the Philippines, Vietnam, Brazil, Malaysia, etc. The Aedes aegypti is a particularly nasty one because it chooses no time in which to strike. In theory, they bite at dusk and dawn, but in practice, they can bite anytime of the day.

How do you know if you have Dengue Fever? Watch out for these symptoms:

1. High fever which lasts from 2 to 7 days, up to 105 degrees Fahrenheit or 40.5 degrees Celsius

2. Severe headache

3. Retro-orbital pain (or pain behind the eye)

4. Muscle aches and pains

5. Severe joint pains (Dengue fever is also known as breakbone fever.)

6. Enlarged lymph nodes

7. General weakness

8. Nausea and Vomiting

9. and the classic Hemorrhagic rash.

This rash is characterized by bright red pinpoints known as “petechiae”. It may spread all over the body. Patients with Dengue fever may also cough up or vomit bits of congealed blood, and may even ooze blood out of various orifices of the body including eyes, nose, mouth, and ears.

This is why Dengue fever is more properly called Dengue Hemorrhagic Fever.

First identified in 1779, Dengue fever up to now cannot be prevented by a vaccine. Likewise, there are no drugs that offer a cure except for supportive therapy. It is crucial then that at the onset of fever and rash, people are advised to consult a physician right away to curb the progress of the disease.

Supportive therapy for Dengue fever includes oral rehydration, platelet transfusion, intravenous fluids, and close monitoring of the patient’s vital signs.

Also, since there is no cure to the dengue virus yet, the only way to address the issue is to target the breeding places of mosquitoes to curtail their spread. As we all know, mosquitoes lay their eggs in stagnant water (Aedes aegypti has been known to favor clean water).

Preventive Ways to Stop Dengue Fever

1. Clean up your backyard.

2. Check for stagnant water, including flower vases, pails, cans, bins, tires, aquariums, puddles, etc. Replace the water in vases regularly, empty the cans and keep them upside down.

3. Buy a mosquito-repellant lotion for you and your family.

4. Opt for long sleeves and pants and, if possible, even socks.

5. If you’re swift, kill a mosquito and more. This is no time to be squeamish.

Just by following these steps and, of course, enjoining everyone in the community, you can stop the spread of Dengue fever. Actually you get to stop the spread of two diseases-Dengue and Malaria-so that’s two birds with one stone. No, we mean mosquitoes.

Dengue Fever Explained

Fever Dengue (pronounced DEN-gee) is caused by viruses that are transmitted by mosquito bites. It is a severe illness that starts suddenly and usually follows a benevolent course with such symptoms as fever, headache, intense muscle and joint pains, exhaustion, lymphadenopathy (swollen glands) and the telltale rash. Dengue is characterized by the presence of what is called the “dengue triad” (headache, fever and rash). There are other signs of dengue like stark pain behind the eyes, gums that bleed, and redness in the palms of hands and soles of the feet. What is Dengue Fever?

Fever dengue strikes those who have low immunity levels. Fever dengue can be caused by any one of four types of the dengue virus: DEN-1, DEN-2, DEN-3, and DEN-4 (the numbers reflect the order of discovery and have no relation to disease severity). An individual can be infected by at least two types, if not all four at different times during his or her life. However, an attack of a particular type of dengue produce lifetime immunity against that serotype which the patient had been exposed to.

There are other names for dengue such as “dandy fever” or “breakbone.” The name “breakbone” was derived because the victims of dengue have contortions because of the intense muscle and joint pains. The name “dandy fever” was derived from the slaves of the West Indies who had contracted fever dengue because of their gait and postures.

The more severe viral serotype of fever dengue is dengue hemorrhagic fever. Signs include headache, rash, fever, petechiae (which are small purple or red blisters just under the skin), bleeding of the gums, blackened stools, and bruising that easily develop. Dengue hemorrhagic fever can be lethal and can develop into the most severe form of dengue which is dengue shock syndrome.

A person who has been bitten by the Aedes mosquito carrying the dengue virus will show signs and symptoms after 3 to 15 days (although it is more common from within 5 – 8 days). The person infected will first experience chills and then headaches or pain when they move their eyes, and lower back pain. The pain in the joints and muscle pain in the legs occur during the first hours. The body temperature will then rise to about 40 degrees Centigrade (or 104 degrees Fahrenheit). The heart rate will remain low (known as bradycardia) and so will the blood pressure (known as hypotension). There will be reddening of the eyes and then there will be a rash or flushing that comes over the face and then goes away. The lymph nodes (glands) in the groin and neck will be swollen.

Most of those who develop fever dengue completely recover within two weeks however there are some who may go through several weeks of feeling depressed and/or tired.

The virus is contracted from the bite of a striped mosquito known as the Aedes aegypti that has been previously bitten a dengue infected person. This mosquito flourishes during the rainy seasons or monsoons but can easily breed in water-filled potholes, drains, flower pots, old tires, plastic bags, and cans all year-round. Only one mosquito bite is enough to inflict the disease.

The dengue virus is not contagious and cannot spread directly from one individual to another. To spread, there must be a pathway that goes “person-to-mosquito-to-another-person”.

Advice from Rentokil on how to control mosquitoes and flies after heavy rain

As Gauteng residents experience flash flooding due to heavy rainfall, Rentokil warns of the impact residual standing water can have on fly and mosquito infestations.
Advice from Rentokil on how to control mosquitoes and flies after heavy rain
Heavy rains in Gauteng this week have seen numerous car accidents, flooding on several roads and reports of lightning strikes. At the time of writing, provincial government has activated a disaster management centre to investigate the trail of destruction and continue with search operations.

As the waters recede over the next days and weeks, residents are going to be faced with another issue; that of residual standing water. Standing water may not seem like a huge concern in light of the damage caused by the flooding, but it has the potential to cause a significant longer-term problem; that of an increase in the fly and mosquito population.

Both flies and mosquitoes lay their eggs in standing water, and hot weather – such as Gauteng residents generally experience between October and March- increases the probability of a large scale infestation because larvae hatch, mature and reproduce at a much faster rate in the heat. Under optimal conditions, fly larvae can mature into adults in as little as four days!

Advice from Rentokil on how to control mosquitoes and flies after heavy rain
This is problematic because both mosquitoes and flies are known to spread disease. Flies carry diseases like malaria, dysentery, gastro-enteritis, typhoid fever, cholera, conjunctivitis, tuberculosis and diarrhoea. They also cause parasitic tapeworms in poultry and horses. Mosquitoes are just as bad, carrying infectious diseases from several different classes of microorganisms, including viruses and parasites. Mosquito-borne illnesses include malaria, West Nile virus, elephantiasis, dengue fever, yellow fever and zika virus.

Whilst there are many DIY options for flies and mosquitoes, most of them don’t fully resolve the problem. DIY solutions may be able to get rid of adult flies and mosquitoes, but the larvae and eggs are often left untouched, resulting in another infestation arising.

Mosquito and fly prevention tips:

If you are keen on getting rid of flies and mosquitoes yourself, there a couple of prevention tips you can enlist which have a proven track record of reducing the presence of both flies and mosquitoes. The most important of these is to eliminate any source of standing water around your home, so that you break the breeding cycle.

Remove any standing water from your garden; empty pots, buckets etc where rainwater may have accumulated
If you have a garden pond, think about adding some goldfish as they will eat fly and mosquito larvae.
Water tanks or jojo’s should be covered with a well- fitting lid.
Change the water in your pets dishes regularly
Maintain your gutter by removing old leaves which can cause blockages and the risk of standing water
Keep grass and weeds trimmed and under control
Inside, keep the air circulated using fans
Install fine mesh screens on doors and windows

With technology, there’s no need to fear the walking dead

What would you do if you were faced with a zombie apocalypse? With the popularity of fiction like The Walking Dead and World War Z, it’s become something of an internet cliché to imagine how you would survive if you were faced with a horde of brain-eaters at your door one day.
With technology, there’s no need to fear the walking dead
©solarseven via 123RF
It’s a fun exercise, but I find it to be a little pointless. Not because a zombie apocalypse might never happen – sometimes when I look around my neighbourhood, I’m convinced it’s already started – but because we have the technology in place to prevent it from spiralling out of control in the first place. Don’t believe me? Let’s strap on our weapons and take a journey through your typical zombie apocalypse.

The virus emerges

It starts slowly. One night, there is a report in the news about some isolated cases of a strange virus that keeps the brain alive after death. Before you know it, pockets of infection are popping up all over the place and an epidemic is well and truly underway. In the prequel series Fear the Walking Dead, this scenario snowballs into a full-blown zombie epidemic. In real life, it’s unlikely we’d get taken by surprise, as the top minds would be closely monitoring the outbreak in real time.

Just take the West African Ebola outbreak, which saw the CDC use analytics to anticipate where the disease was likely to spread. Anyone who travelled by airplane during that time will also remember the screening processes in place at airports to detect potential Ebola carriers. Similarly, with the zombie virus, technologies like advanced video screening would be able to better identify potential infected individuals at airports and bus stops, preventing a global spread.

Walkers at your door? There’s an app for that

You typically wouldn’t see a cellphone in a zombie movie, but in the real world, mobile devices, not machetes, would make for the best weapons against the undead. You can bet that the dead rising would be a main topic of conversation on social media, making it the most effective platform to educate, inform and gather data on the threat.

The likes of Facebook Safety Check and Google Person Finder would certainly take centre stage, and a range of other digital tools would doubtlessly emerge in response to the new problems. Imagine a mobile app like Waze for zombies, using crowd-sourced information to pinpoint the safest route to take home. Or a Tinder for survivors, letting you meet up in safe places and send out a request for a rescue.

It’s not nearly as farfetched as it sounds. The CDC already uses social media to educate people on emergency preparedness and WHO has created apps to help fight Zika, Dengue Fever and other tropical diseases. What’s more, the amount of real-time data that would pass through social media would be invaluable in detecting and stopping the spread. Governments are already exploring how to use data from Facebook and Twitter to predict flu outbreaks.

Zombie-proof societies

As we can see, data is key to preventing us from descending into our own World War Z. And, as the Internet of Things takes hold in our society, the chances of a zombie apocalypse affecting us will become even more minuscule.

Take the hordes themselves, one of the most dangerous aspects of any zombie apocalypse as The Walking Dead shows. Here, we could use geospatial mapping to predict their movements. In our zombie-style IoT, drones could go around following hordes and tracking their movements, in order to warn areas in danger of being overrun.

Okay, so we’ve successfully prevented the downfall of society and ensured that casualties are minimal. But how do we get rid of the zombie virus once and for all? Here’s where wearables could shine.

It’s not exactly easy to gather patient data on a person threatening to turn into a shambling zombie at any second. But should people already have some sort of healthcare monitoring device on them before they’re bitten, real-time data would be made available to researchers without putting anyone else in danger.

Our hypothetical zombie apocalypse scenario clearly has a lot of lessons to offer around healthcare and disaster management. But any enterprise can use the same digital-first mindset to tackle their own metaphorical hordes. Zombies may be a threat, but their ultimate defeat comes from identifying and adapting to their patterns of behaviour. The same is true for any business threat, whether it’s diminishing revenue or lack of innovation.

Preventive Measures Against Dengue

The World Health Organization’s World Health states that as of 1998, infectious and parasitic diseases slashed one-third of all deaths in the world in 1997 and 43% of deaths among developing nations. The low rate in Cuba is an exception because of the possible high educational and health awareness rate with regards to the disease in the country. This can be attributed to the consistent improvements of Cuba’s health system over the past 50 years which was further amplified b it speedy modernization. The United States, as nation thought of by most people as a world leader is even inferior to the Cuban health care system, a sheer proof that you don’t need power to heal. About 50 years back, a town in the Caribbean which happens to be a part of Cuba decided it has to hasten the pace in terms of medical education. This is when several mass infections hit the nation killing many, among these viral killers are Dengue. Today,Cuba hasa population of about 11 million which are all served by dedicated health workers which includes more than 70,000 medical doctors all working in a first class medical system. Now isn’t this an inspiring scenario for other developing countries? I mean if Cuba can do it, why cant they? It is believed that corruption and not simple lack of resources causes nation to die of any viral epidemic. During the 1960s, Dengue casualties were reduced significantly with the advent of vaccines and anti-biotic along with deadly viruses such as smallpox, poliomyelitis, and acute rheumatic fever. But Dengue is more than just a seasonal disease, as opposed to the others mentioned above. It is a killer spurned by poverty, social exclusion, health systems, environments, food security, water and sanitation. To win against it, proper education is very important. To truly win against the disease, public health vigilance in terms of modern structures will be needed. This will include disease monitoring, disease prevention, communication, and financial supports are all needed. Maria Guzman and her husband are both working to battle against Dengue for 20 years now. She works at the Tropical Medicine Institute Pedro Kourí (IPK), in Havana, Cuba as one of its head virologist. Her work there has been acknowledged to have made significant contributions in the field of pathogenesis, diagnosis, epidemiology, and clinical progression of this disease. The good doctor has been with the Cuban academy of Science for the Developing Worlds but she concentrates in the fight against Dengue. She is currently a member of several the Pan American Health Organization (PAHO), World Health Organization (WHO), and the Special Programme for Research and Training in Tropical Diseases (TDR). The Dengue prevention organization also believes that educational programs are not prioritized seeing that resources to implement them are not evaluated on a regular basis. The education is somewhat mixed-up and done by inexperienced individuals who at most times give confusing instructions. The training of the staff to be truly credible in educating the public about dengue costs too much for countries whose number one problem is famine. Governments have to keep in mind that if it wants to prevent a mass outbreak, it should make dengue prevention a priority. They don’t have to spend much, Dengue prevention is all about making do with available resources. Published at: https://www.isnare.com/?aid=263674&ca=Medicines+and+Remedies

Dengue Facts And Figures

If there’s one insect that can truly be called a pest, it’s the mosquito. Incredible as it sounds, this tiny insect can cause a host of diseases ranging from malaria, filariasis, yellow fever, and encephalitis (the inflammation of the brain). One of the most common diseases transmitted by mosquitoes is dengue and it’s found in over 40 countries. Since it first appeared in Southeast Asia in the 1950s, dengue outbreaks have increased and have been reported in Indonesia, Malaysia, India, Burma, and Thailand. Over 2.5 million people are at risk, according to the World Health Organization (WHO). Millions of infections occur yearly and about 500,000 people are hospitalized because of dengue. Ninety-five percent of those affected are children. Not all mosquitoes transmit the dengue virus. There are over 160 different species but only two cause trouble: the Aedes albopictus and more commonly, the Aedes aegypti. Only female mosquitoes bite and they’re active two hours after sunrise and two hours before sunset. Mosquitoes normally feast on nectar and plant juices. The female needs blood to nourish its eggs. It becomes infected with the dengue virus when it bites a person suffering from the disease. The infected mosquito then spreads the disease when it bites others. “There is no way to tell if a mosquito is carrying the dengue virus, therefore people must protect themselves from all mosquito bites,” warned WHO. Dengue mosquitoes like to hide in closets and other dark places. Outside, they prefer cool and shaded areas such as school grounds, park, and malls. The female breeds in anything that holds stagnant water like barrels, drums, old tires, pots, flower vases, bottles, roof gutters, refrigerator drip pans, and other places that collect rainwater. Many factors contribute to the spread of dengue. These include climate changes brought about by the El Nino phenomenon, increasing urban populations, and poverty. Mosquito breeding sites have also increased due to poor water storage and sewage systems, uncollected garbage, and infrastructure projects with stagnant pools. Mass transportation has made it easier for mosquitoes to reach other areas and move infected humans. There are two forms of dengue. Dengue fever is a severe flu-like illness that affects older children and adults but is rarely fatal. It’s characterized by sudden high fever, headache, pain behind the eyes that worsens with movement, and muscle and joint pains. Later, a measles-like rash appears on the chest and upper limbs and there is nausea and vomiting. The more severe form of the disease is dengue hemorrhagic fever (DHF) which is fatal in children. Its symptoms are similar to dengue fever but it causes bleeding from the nose, mouth, and gums and shock leading to death. Other signs of DHF are severe stomach pain, pale, cold or clammy skin, frequent vomiting, sleepiness, excessive thirst, rapid weak pulse, and difficulty in breathing. If you suspect you have dengue or DHF, see a doctor immediately. Up to 20 percent of people with severe dengue or DHF may die if not properly diagnosed and treated. To keep your body strong and healthy, eat right and follow a regular exercise program.

Dangers Of Dengue

Even the Asia’s cleanest city cannot escape deadly mosquito bites. Singapore reached a record high of dengue incidence in 2005, reaching 12,700 and nine deaths. But the cleanliness-obsessed Singaporean government is not taking the matter with no serious efforts. The government has taken the fight against dengue in a higher level by going down the ranks. The battle to curb mosquito bites has been waged on a house-to-house basis with the search-and-destroy campaign. The campaign will run with almost a thousand health officers and volunteers going to every household in areas where incidence of dengue are high. Manual household checks will be done to determine breeding spots and living areas of dengue-carrier mosquitoes. The rationale behind the campaign is that individual household checks can yield to specific preventive measures believed to be more effective than blanket policies used in the past. People and travelers alike, who are already diagnosed with dengue, will be required to use insect repellents so as to prevent more transmission from happening. The recent outbreak of dengue in Singapore is believed to have resulted in more damages than what SARS did in 2003. The uncontrollable rise in dengue incidence has left the government clueless for some time on what else is needed to be done, given all the existing measures they have been relying to, which in fairness succeeded in mitigating the extent of cases in the past years. The new improved per-household campaign has 30 million Singaporean dollars for its budget and multi-lateral efforts from local and foreign health agencies. Actually, it is not only Singapore that is suffering from increased rates of dengue incidence and dengue-related casualties. Indonesia, with the most cases, had 80,837 cases and 1,099 deaths during the entire year of 2005. Malaysia had 32,950 cases and 83 deaths. The Philippines islands, with 21,537 cases and 280 deaths, is also on the record for the year 2005 alone. But the increase in the rates of cases in Singapore is the highest in the Asian region, resulting in cancellation of hospital surgeries to give bed spaces for dengue patients. Dengue hemorrhagic fever (DHF) and dengue fever are acute febrile diseases transmitted by mosquito bites by mosquitoes from the Aedes aegypti group. The term “dengue” is traced to a Spanish attempt at the Swahili phrase “ki denga pepo,” which means “cramp-like seizure caused by an evil spirit.” The first outbreak is believed to have occurred in the Caribbean in 1827-1828. The dengue virus belongs to the genus Flavivirus of the family Flaviviridae. This deadly infectious disease is manifested via recurring fever, extreme headaches, rashes, and muscular pains. The rash is distinctly bright red petechia, usually appearing on the lower limbs at the beginning, and the chest later on. But in some cases of severeness, the rashes can spread all over a patient’s body. Other signs like gastritis, abdominal pain, diarrhea, nausea, and vomiting can also be observed. A typical dengue fever will last about six up to seven days. The fever will peak before it ends. When a patient is suffering from a dengue case, the platelet count in the blood drops, resulting in further health hazards. As of now, there is still no commercially available vaccine for the flavivirus. The Pediatric Dengue Vaccine Initiative (PDVI) initiated in 2003 is yet the farthest scientists have gone in coming up with a vaccine to directly combat the virus causing dengue fever. The current measures being undertaken to cure dengue-inflicted people are mainly of supportive measures only. High oral intake of fluids or the supplementation of intravenous fluid are prescribed to prevent dehydration. In worst cases where in the platelet count is alarmingly low, blood transfusion is the last resort. Still, as a cliche goes, prevention is still better than cure. This is especially true in the absence of a specific cure as in the case of the deadly dengue. Basic prevention measure is the elimination of hubs, where mosquitoes thrive. This will not only deny existence for dengue-carrying mosquitoes but it will also affect those that carry malaria virus. Individual, community, and governmental efforts should play hand-in-hand to ensure the effectiveness of this basic measure. Spraying of insecticides in public areas, cleaning of clogged drainage systems in the community, and keeping each household free of breeding spots are the most practical steps in protecting the community from dengue. Personal prevention may be in the form of using mosquito nets, applying repellents, covering of exposed skin, using bed nets, and avoiding endemic areas. Other governments can also come up with innovative measures like what Singapore initiated. Published at: https://www.isnare.com/?aid=83058&ca=Wellness%2C+Fitness+and+Diet

Dengue and Swine Flu Causes and Symptoms and Natural Treatment of Dengue and Swine Flu

Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes. It is an acute illness of sudden onset that usually follows a benign course with symptoms such as headache, fever, exhaustion, severe muscle and joint pain, swollen glands (lymphadenopathy), and rash. The presence (the “dengue triad”) of fever, rash, and headache (and other pains) is particularly characteristic of dengue. Other signs of dengue fever include bleeding gums, severe pain behind the eyes, and red palms and soles. What Causes Dengue Fever? Dengue fever can be caused by any one of four types of dengue virus: DEN-1, DEN-2, DEN-3, and DEN-4. Infection with one virus does not protect a person against infection with another. A person can be infected by at least two, if not all four types of the dengue virus at different times during a life span, but only once by the same type. Symptoms of Dengue 1.Severe headache 2.Pain behind the eye 3.Severe joint pain 4.Severe muscle pain 5.Nausea 6.Rash Treatment of Dengue The first step in treating dengue fever is prevention. Prevention measures include controlling mosquito populations in warm sub-tropical and tropical areas of the world. This includes draining areas and objects that can hold standing water and become a breeding ground for mosquitoes, such as old tires, puddles, and bird baths. Wearing insect repellent that contains DEET, picaridin, or oil of lemon eucalyptus and wearing protective clothing that covers the whole body are also important preventive measures. There is no definite treatment for or vaccine to prevent dengue fever. Most people who get dengue fever will recover in about 2 weeks to a month by getting plenty of rest, increasing fluid intake and taking acetaminophen (Tylenol) for fever and body aches. People with dengue fever should not take aspirin or medications that contain aspirin because it increases the risk for severe bleeding. Swine Flu Swine flu has been creating a terror effects all round the globe and has been declared epidemic in most part of the world. This is caused by influenza A (H1N1) virus. Swine Flu is H1N1, or pig influenza – an acute respiratory infection, usually affects pigs, but the ability to pounce and man. Presumably, the disease appeared after the animal is picked up one of several varieties of the virus – a new strain, scientists have found traces of the North American pig flu or swine flu, the North American avian influenza, and swine and human virus commonly found in Asia and Europe. The first cases of human infection by virus reported on 18 March in Mexico.

Dengue Fever: Prevention, Symptoms and Treatment

With the arrival of monsoons, the threat of another dengue fever outbreak looms large particularly in tropical regions like India etc. Though efforts are on by the governments to raise awareness and take necessary steps to manage dengue fever cases better this time, but every individual will also need to do his/her bit to ensure that we do not witness a repeat of last year. In this blog post, we’ll share some information about dengue virus and steps which should be taken to prevent as well as manage it effectively. How is dengue virus transmitted? What are the important preventive measures? Dengue virus is a mosquito-borne virus which is transmitted by female mosquitoes primarily of the species Aedes aegypti. Aedes mosquito is a small, dark mosquito with white lyre shaped markings and banded legs. This mosquito ususally bites indoors and primarily bites during the day time (though it can bite at night as well in well lit areas). It is extremely common in areas without piped water systems as these mosquitoes depend largely on water containers to lay their eggs. An important point which is unfortunately largely ignored is that Aedes mosquito breeds in fresh clean water as opposed to standing water or dirty drains which we normally associate with mosquitoes. Thus, it extremely important to ensure that there are no water filled containers e.g. old broken goods kept at rooftops, water coolers, pet-watering dishes etc in our surrounding areas. Apart from that, it is recommended to wear full sleeve shirts, long pants, shoes during the day time when these mosquitos are active and apply mosquito repellent over the exposed skin. What are the symptoms of Dengue Fever? Symptoms of dengue fever usually begin 4-10 days after one has been bitten by an infected mosquito. The symptoms may range from no signs (during mild cases of dengue fever) to bleeding from nose, mouth, severe abdominal pain etc. The principle symptoms though are: High feve Severe joint and muscle pain Swollen lymph nodes, headaches Exhaustion Rashes Symptoms may rarely include minor bleeding from gums or nose as well. Is there any treatment? There is no defined treatment for a dengue infection. Typically, it is recommended that patients should avoid ibuprofen, asprin or asprin containing drugs as these medicines increase the risk of bleeding. Patients should rest and keep themselves hydrated and should be in contact with their physicians. You may ask why keep in touch with physician when there is no treatment? A valid question but dengue requires symptomatic treatment i.e. treatment is concerned with relief of the symptoms. If ignored, in certain cases dengue fever can prove to be fatal. The key for effective management of dengue fever is early recognition and understanding of the clinical problems during the different phases of the disease. Why are diagnostic tests needed then? The difficult part in early detection of dengue is that frequently, the symptoms of dengue fever are not very different from other types of fevers also prevalent during this season. This problem is addressed through diagnostic tests available in laboratories. A common misconception is that dengue fever is extremely dangerous and can lead to fatality in majority of the cases. You’ll be surprised to know that only a very small fraction (0.37% last year [1]) of dengue fever cases result in a fatality. In most of the cases even an admission into a hospital is not needed. Only thing needed from our side is that we need to be extra cautious particularly during the months of August – November and visit a physician immediately in case of fever.
