World Mosquito Day: Dengue, chikungunya, malaria symptoms to watch

World Mosquito Day on August 20 highlights the need to identify mosquito-borne diseases. Dengue, chikungunya and malaria share symptoms such as fever, headache and body aches, making diagnosis difficult. Severe joint pain in chikungunya, bleeding and abdominal pain in dengue, and chills or sweating in malaria can help differentiate them. Timely testing and medical care can prevent complications.
