Dengue is a viral infection transmitted by the female mosquito belonging to the Aedes aegypti species. The same species are also responsible for spreading other infections such as chikungunya, yellow fever and Zika viruses.
Geographically,dengue is widespread throughout the globe, with risk influenced by rainfall, temperature, relative humidity and unplanned rapid urbanization. In tropical regions like India where rainfall is a seasonal phenomenon, dengue fever is synonymous with the monsoon, being one of the common most monsoon fevers.
Dengue is manifested usually as rise of temperature. Although fever could be serious, dengue is not very commonly fatal.
Dengue should be suspected when a high fever (40°C/104°F) is accompanied by any 2 of the following symptoms:
Severe dengue warning signs that suggest a severe dengue infection are as follows:
Although dengue is not potentially fatal, a rise in temperature should be a sign to see your doctor especially during monsoon.
Simple measures like prevention of mosquito breeding and use of mosquito repellents could serve the purpose.
Covering, emptying and cleaning of domestic water storage containers, applying appropriate insecticides to water storage outdoor containers and personal protection from mosquito bites.
Most importantly, early diagnosis is the key. Especially with monsoon fevers where fever could mean anything from malaria to dengue to chikungunya.
A doctor may order one or more tests to diagnose dengue:
Other blood tests are also done to monitor dengue fever like CBC, ESR, LFT, KFT etc.
Monsoon fevers are often a challenge to diagnose and treat.In such cases, PCR tests should be preferred for early diagnosis.FD-5 or Fever Detect 5 in 1 is a PCR based test which can detect 5 common monsoon fevers namely; Dengue, Chikungunya, Malaria, Leptospirosis and Typhoid with a single blood sample.
