Questions & Answers

Q: How is malaria transmitted?

Malaria is transmitted through the bite of a female anopheles mosquito that carries the parasite. The mosquito becomes infected by biting someone with malaria and then passes it on to the next person it bites.

Q: Which population is most affected by malaria?

Malaria affects primarily people living in malaria-endemic areas, with sub-Saharan Africa having the highest burden. Children under five are particularly vulnerable, accounting for almost 80% of malaria deaths.

Q: What are the health consequences of malaria in pregnancy?

Pregnant women with malaria are at high risk of adverse outcomes, including low birth weight, spontaneous abortion, stillbirth, premature delivery, and severe anemia in both the mother and baby.

Q: What are the economic consequences of malaria?

Malaria has significant economic consequences, with individuals experiencing multiple bouts of illness per year and losing work days. The indirect costs of lost work and wages often exceed the direct cost of treatment. It also impacts healthcare systems and economies in malaria-endemic countries.

Q: Are there effective vaccines against malaria?

Currently, there is no approved or widely available malaria vaccine. However, significant progress has been made in vaccine development, and efforts are underway to develop a safe, effective, and affordable vaccine.
