Dengue is a viral disease caused by the dengue virus (DENV), which has four different serotypes (DENV-1 to DENV-4). A person can get infected more than once because infection with one serotype does not provide lifelong immunity against the others. A second infection may increase the risk of developing severe dengue.
Causes of Dengue
Dengue spreads through the bite of an infected female Aedes mosquito. The disease does not spread directly from person to person.
Common factors that increase the risk include:
-Stagnant water around homes
-Poor sanitation
-Monsoon and humid weather
-Living or traveling in dengue-prone areas
-Inadequate mosquito control measures
Dengue is a preventable disease that requires awareness, early diagnosis, and timely medical care. Recognizing symptoms early, staying well hydrated, avoiding self-medication with NSAIDs, and eliminating mosquito breeding sites can greatly reduce the risk of severe illness. During the monsoon season, taking preventive measures at home and seeking prompt medical advice for persistent fever can make a significant difference in recovery.
