Can malaria be cured completely?

Yes, malaria can be fully cured with prompt and appropriate antimalarial treatment. However, P. vivax and P. ovale can remain dormant in the liver and cause relapses if not treated with primaquine.

Is there a vaccine for malaria?

The RTS,S/AS01 (Mosquirix) vaccine is approved for use in children in endemic regions and reduces severe malaria cases by about 30%. Newer vaccines such as R21/Matrix-M show even higher efficacy in clinical trials.

How long after a mosquito bite do symptoms appear?

Symptoms typically appear 10 to 15 days after being bitten by an infected mosquito. Some Plasmodium species can remain dormant for months before causing symptoms.

Malaria

Malaria is a life-threatening mosquito-borne disease caused by Plasmodium parasites transmitted through the bite of infected Anopheles mosquitoes. Symptoms typically appear 10–15 days after the infective bite and include high fever, chills, and flu-like illness. Without prompt treatment, severe malaria can lead to organ failure and death.
