Dengue / Chikungunya

 Mostly carried by Aedes aegypti mosquitoes, dengue and chikungunya are mosquito-borne viral diseases. Common in tropical and subtropical areas, these diseases sometimes flare during the monsoon season. Although dengue and chikungunya have similar transmission routes and overlapping symptoms, they are caused by separate viruses: dengue is caused by the dengue virus (DENV), while chikungunya is caused by the chikungunya virus (CHIKV). 

These diseases usually present with high temperature, severe headache, pain behind the eyes, joint and muscular pain, skin rashes, and in severe cases, bleeding and low platelet count. Conversely, chikungunya is distinguished by abrupt high fever, severe joint pain, muscle aches, tiredness, and rash. Chikungunya's joint discomfort is more disabling since it may last for weeks or even months.
For either condition, there is no particular antiviral medication. Management consists of rest, fluids, and drugs to lower fever and pain; avoid aspirin and NSAIDs in dengue to lower bleeding risk. Preventive measures centre on mosquito control—that is, removing standing water, using repellent, and dressing in protective gear.
Key to recovery and avoidance of problems are early diagnosis and supportive treatment. Controlling outbreaks depends much on public knowledge and community initiatives.
