Dengue Fever and West Nile Virus

Breakout of Dengue Fever Increases

In 2011, Key West suffered a breakout of Dengue Fever, which is spread by mosquitoes. This was the first breakout in the U.S. Puerto Rico is another place where Dengue Fever is a large problem. Now, Dengue Fever has hit the continental US, much of South America, Greece, many countries in southern Asia and Africa.This disease has become a world wide problem.

The mosquitoes pass the dengue fever to a person and to each other. At this point authorities state 5% of Key West residents have been affected. There is some chance that this fever will spread in the more tropical areas of the United States.

The female Aedes aegypti and the Aedes albopictus mosquitoes are the primary vectors for the spread of the fever. Biologists have actually created a mosquito killing bacteria to fight Dengue fever.

Key West literally placed thousands of mosquito traps, which covered hundreds of acres as they fought these mosquitoes. People are most susceptible to getting bit at dawn and dusk.
FDA Approved Test for Dengue Fever

The FDA announced on June 21, 2012, that the CDC has developed a new test to detect dengue fever. The test is called CDC-DENV-1-4 Real Time RT PCR Assay. This test will help diagnosis the fever within 7 days of when the symptoms first appear. All four types of dengue fever can be diagnosed utilizing this test.

Dengue fever Symptoms

Dengue fever is a viral infection that is debilitating but not usually fatal in otherwise healthy people. It can be diagnosed by a blood test. There is no vaccine to prevent Dengue fever at this time.

Once bitten it takes 6-7 days for the disease to develop. The symptoms are fevers as high as 104-105, severe headache behind the eyes, rash, swollen lymph nodes, vomiting muscle and joint pain with general malaise. The severity of the joint pain has given dengue the name “breakbone fever.” The rash appear 3-4 days after the beginning the fever. The illness may last up to 10 days but full recovery often takes a month. Children and young adults have about a 5% death rate
