Malaria is a disease transmitted through the bite of a contaminated mosquito. The first symptoms usually appear between 7 and 30 days after the infecting bite, but in some cases, it can take up to 1 year for the disease to develop. Among the signs of malaria, an acute fever, chills and flu-like symptoms can be quoted. Without adequate treatment, malaria can be fatal. 


All the travelers going to Africa, to Asia, to Central America, to Eastern Europe, to South America, to the Caribbean and to South Pacific islands are at risk for malaria. This risk considerably increases if they spend a lot of time outdoors or if they sleep outside. Every year, more than 1 500 cases of malaria, including 5 deaths on average, occur among international travelers in the United States. 


If you intend to travel to a country at risk for malaria, you should take some precautions to avoid being infected with the disease and to protect yourself efficiently against mosquito bites.

  • Before your departure, you should see a doctor. He will help you to evaluate your risk of exposure to malaria and, if necessary, he will prescribe you medicines to prevent the disease. Note that these drugs must be taken before, during and after your trip without interruption.
  • While traveling, protect yourself efficiently against mosquito bites, especially between sunset and sunrise. Wear protective clothes, such as trousers, long-sleeved shirts and hats. Apply mosquito repellent on exposed skin. Preferably choose a repellent providing long lasting protection and containing a high percentage of active ingredients, such as DEET, Picaridin and IR3535. Always use repellents with caution and follow product instructions. Avoid applying repellent in your eyes, in your mouth and on your hands. When using sunscreen, apply the sunscreen first and the repellent right after. You can also use Permethrin-treated clothing and gear, which provide optimal protection against mosquitoes, even after several washes. You can find pre-treated items in specialized shops, but it is also possible to treat your own belongings, such as pants, socks, boots and tents. Avoid direct contact with skin when handling Permethrin. Always sleep under a mosquito net, especially if your room is exposed outdoors or if you are sleeping outside.


If you have been bitten by a mosquito, avoid scratching the affected area. Immediately apply hydrocortisone-based cream or calamine lotion to reduce itching. 


If you feel sick after traveling in a country at risk for malaria, you should see a doctor as soon as possible, especially if you have a fever. Inform him/her of the areas you have visited and of your activities there.
