What is Malaria? It's Symptoms, Causes and Prevention:

Malaria is caused by a parasite spread through mosquito bites, leading to symptoms like fever, chills, and nausea.

It is prevalent in tropical and subtropical regions, with nearly 290 million cases annually.

The World Health Organization recommends preventive measures, including bed nets and vaccines for children in high-risk areas.

Symptoms often begin weeks after a mosquito bite but can lie dormant for up to a year in some cases.

Malaria transmission involves mosquitoes biting infected people and spreading parasites to others.

Besides mosquito bites, malaria can be transmitted through blood transfusions and from mother to child.

High-risk regions include Sub-Saharan Africa, South Asia, and parts of Central and South America.

Serious complications of malaria include cerebral malaria, organ failure, and anemia.

To prevent malaria, use insect repellent, wear protective clothing, and sleep under treated bed nets.

A malaria vaccine is recommended for children in high-incidence countries, with ongoing research to improve prevention.
