Risk of malaria is very high particularly for travellers going to Asia, Africa and South America. Malaria is caused by a bite from an infected mosquito. Malaria can be fatal if not treated promptly. It is important for travellers to take chemoprophylaxis anti-malarial drugs to prevent the malaria infection. Malaria in most countries is resistant to commonly used drugs such as chloroquinine.
It is important to visit a travel clinic so that you get the appropriate anti-malarial drugs to prevent the malaria infection. It is equally important for travellers to use mosquito repellents medications such as DEET and clothes treated with anti-malarial sprays (premethrin) to prevent the mosquito bites.
