Chloroquine-resistant malaria is now found in all malarious areas of the world with the exception of The Middle East, Haiti and Central America. Personal measures such as DEET- containing repellents and mosquito nets are extremely important in preventing malaria. Malaria is often misdiagosed and mistreated in travellers who return home. It is a myth that once you have malaria, you have it for life. There are two strains of malaria which may persist in the liver and recur, Plasmodium vivax and Plasmodium ovale .
Malaria is usually a preventable infection.
There are good drugs to prevent malaria. Unfortunately, there are no perfect ones. Many people say that antimalarials are worse than the disease. They only suppress it. But with personal measures, the risk of infection can be greatly reduced.
