Vector-borne diseases, like malaria and dengue, are transmitted through the bite of infected mosquitoes. Malaria is caused by a parasite and can lead to fever, chills, fatigue, and anemia, while dengue is a viral infection that causes high fever, severe headache, joint pain, rash, and bleeding. Both diseases are common in tropical regions and can be severe if not treated promptly. Prevention involves using mosquito repellent, bed nets, and controlling mosquito breeding sites. Treatment for malaria includes antimalarial drugs, while dengue requires supportive care to manage symptoms. For expert care and timely treatment, consult Dr. Aparna More today!
