What Is Malaria Prophylaxis?

What is malaria prophylaxis?

Malaria prophylaxis refers to preventive medication, known as antimalarial drugs, taken to protect against malaria when traveling to areas where the disease is present. Malaria is a serious and potentially fatal illness spread by the bite of infected mosquitoes, and it occurs in many tropical and subtropical regions. According to the CDC, travelers can prevent malaria by taking antimalarial medication and avoiding mosquito bites, and there is currently no malaria vaccine available in the United States for general travel use. Prophylaxis means taking the medicine on a schedule around your trip to keep protective levels of the drug in your body. Because malaria can be life-threatening, taking recommended prophylaxis for high-risk destinations, together with bite-prevention measures, is an important part of preparing for travel to affected areas.

How does malaria prophylaxis work?

Malaria prophylaxis works by maintaining a protective level of antimalarial medication in your body so that if an infected mosquito bites you, the drug helps prevent the malaria parasites from establishing an infection. To do this, the medication must be taken on a specific schedule that typically begins before you enter the malaria area, continues throughout your stay, and importantly continues for a period after you leave, since some regimens require ongoing doses to remain effective; the exact timing depends on the drug. Taking the medicine exactly as prescribed, without missing doses, is essential for it to work. Prophylaxis is highly effective but not 100 percent guaranteed, which is why it is always combined with measures to avoid mosquito bites, such as repellent, covering skin, and sleeping under treated nets, for the best protection.

Do you need malaria prophylaxis?

Whether you need malaria prophylaxis depends on your destination and itinerary, and this is a decision to make with a healthcare professional. Malaria risk varies widely by country and even by region within a country, by the time of year, and by the type of travel, so some destinations warrant prophylaxis while others, with little or no malaria, call only for mosquito-bite precautions. The specific medication recommended also depends on the destination, because malaria parasites in some areas are resistant to certain drugs, as well as on your health, other medications, and personal factors. Because of this complexity, you should not decide on your own; a doctor or travel clinic assesses your risk based on your exact plans and health and advises whether you need prophylaxis and which drug is appropriate for you.

How do you get malaria prophylaxis?

You get malaria prophylaxis by consulting a doctor or a travel clinic, ideally well before your trip, since some regimens must be started days or weeks in advance. The healthcare professional will assess your destination, itinerary, and medical history to determine whether you need antimalarial medication and, if so, prescribe the most suitable one, along with instructions on exactly when to start, how to take it, and when to stop. It is important to obtain your antimalarial drugs before you travel, in your home country, rather than buying them abroad, since medications sold in some destinations can be counterfeit or substandard and may not work. Take the medication precisely as prescribed, keep up mosquito-bite prevention, and seek medical care promptly if you develop a fever during or after travel, mentioning where you have been, as malaria requires urgent treatment.
