Dengue fever is a mosquito-borne disease caused by dengue virus, prevalent in tropical and subtropical areas. It is frequently asymptomatic; if symptoms appear they typically begin 3 to 14 days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin itching and skin rash. Recovery ...
The origins of the word "dengue" are not clear, but one theory is that it is derived from the Swahiliphrase Ka-dinga pepo, which describes the disease as being caused by an evil spirit. [40] The Swahili word dinga may possibly have its origin in the Spanish word dengue , meaning fastidious or careful, which would describe the gait of a person ...
Accordingly, while primary (first) infections cause mostly minor disease (dengue fever) in children, re-infection is more likely to be associated with dengue hemorrhagic fever and/or dengue shock syndrome in both children and adults. [37] Dengue encompasses four antigenically different serotypes (dengue virus 1–4). [38]
Those that do develop symptoms typically recover after about one week, said the Florida Department of Health in Miami-Dade. About 1 out of 20 people who initially get sick with dengue will develop ...
Dengue fever is on the rise in Puerto Rico, and island officials have declared it an epidemic. At least 549 cases have been reported so far and more than 340 people have been hospitalized ...
The plaque reduction neutralization test is used to quantify the titer of neutralizing antibody for a virus. [1] [2] The serum sample or solution of antibody to be tested is diluted and mixed with a viral suspension. This is incubated to allow the antibody to react with the virus. This is poured over a confluent monolayer of host cells.
Other children then became victims to the new symptom. [4] Epidemic dengue has become more common since the 1980s. By the late 1990s, dengue was the most important mosquito-borne disease affecting humans after malaria, with around 40 million cases of dengue fever and several hundred thousand cases of dengue hemorrhagic fever each year ...
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
