Dengue fever, a mosquito-borne viral illness, has emerged as a significant global health concern, particularly in tropical and subtropical regions. Understanding its causes, symptoms, prevention, and treatment is crucial for safeguarding your health and the health of your community. What is Dengue Fever? Dengue fever is caused by the dengue virus, transmitted primarily by the Aedes aegypti mosquito. This virus comes in four different serotypes (DENV-1, DENV-2, DENV-3, and DENV-4), which means an individual can be infected up to four times. How is Dengue Fever Spread? Dengue fever is not directly transmitted from person to person. Instead, it spreads through the bite of an infected Aedes mosquito. When a mosquito bites an infected person, it picks up the virus and can then transmit it to others through subsequent bites. Recognizing Dengue Fever Symptoms Dengue fever symptoms typically appear 4-10 days after the mosquito bite and can last up to 10 days. Common symptoms include:  * Hi...

Malaria: A Global Health Challenge Introduction: What is Malaria? Malaria is a life-threatening disease caused by Plasmodium parasites, transmitted to humans through the bite of infected female Anopheles mosquitoes. It remains a major public health concern, especially in tropical and subtropical regions. --- How Does Malaria Spread? The transmission cycle begins when an infected mosquito bites a person, injecting parasites into the bloodstream. These parasites travel to the liver, multiply, and re-enter the bloodstream, where they invade red blood cells and cause the typical symptoms of malaria. Lifecycle of Malaria Parasite: 1. Mosquito bite injects parasites into the blood. 2. Parasites multiply in the liver. 3. Infected red blood cells rupture, causing illness. 4. A new mosquito bite carries the parasite to another host, continuing the cycle. --- Common Symptoms of Malaria Fever and chills (cyclic fevers are a hallmark of malaria) Headaches Nausea and vomiting Sweating and muscle pa...
