New treatments have been developed but they come at a high cost. An adult dose of a newer drug may be 10 to 20 times more expensive than older anti-malarials. One reason for the rise of drug resistance is that people do not finish their course of treatment but stop when they start to feel better. Poorly trained pharmacists and store owners may also allow patients to buy just a portion of a course of drugs, as that is all they can afford, which contributes to dangerous drug resistance.
Cost varies enormously, but in many of the countries most affected, the cost of treatment is unmanageable for poor and marginalised communities. Sign up to be a part of our global movement for health justice, including how you can get involved in our work through campaigning and fundraising.

Research to develop safe and effective global vaccines for malaria is ongoing, with the licensing of one vaccine already having occurred in Europe. No vaccine is yet licensed in the U. While malaria is not endemic to the U.
The Centers for Disease Control advise travelers to take the following precautions :. The WHO points out that these are not harmful for people, as the concentration of pesticide is only strong enough to kills mosquitoes. While away, travelers should, where possible, avoid situations that increase the risk of being bitten by mosquitoes. Precautions include taking an air-conditioned room, not camping by stagnant water, and wearing clothes that cover the body at times when mosquitoes are most likely to be around.
For a year after returning home, the traveler may be susceptible to symptoms of malaria. Donating blood may also not be possible for some time. Malaria happens when a bite from the female Anopheles mosquito infects the body with Plasmodium. Only the Anopheles mosquito can transmit malaria. The successful development of the parasite within the mosquito depends on several factors, the most important being humidity and ambient temperatures. When an infected mosquito bites a human host, the parasite enters the bloodstream and lays dormant within the liver.
The host will have no symptoms for an average of The liver then releases these new malaria parasites back into the bloodstream, where they infect red blood cells and multiply further. Some malaria parasites remain in the liver and do not circulate til later, resulting in recurrence.
To achieve sustainable control over malaria, healthcare professionals will need a combination of new approaches and tools, and research will play a critical role in development of those next-generation strategies. Malaria has a significant impact on the health of infants, young children, and pregnant women worldwide. More than , African children under the age of five die of malaria each year.
Malaria also contributes to malnutrition in children, which indirectly causes the death of half of all children under the age of five throughout the world. Fifty million pregnant women throughout the world are exposed to malaria each year. In malaria-endemic regions, one-fourth of all cases of severe maternal anemia and 20 percent of all low-birthweight babies are linked to malaria.
Scientists are working to better understand how malaria uniquely affects children and pregnant women and to develop new research tools, methods, and products appropriate for these populations. The development of a safe and effective vaccine against malaria will be critical in malaria control, prevention, and eradication efforts.
Check with your GP to make sure you're prescribed a medication you can tolerate. You may be more at risk from side effects if you:. If you've taken antimalarial medication in the past, don't assume it's suitable for future trips.
The antimalarial you need to take depends on which strain of malaria is carried by the mosquitoes and whether they're resistant to certain types of antimalarial medication. In the UK, chloroquine and proguanil can be bought over-the-counter from local pharmacies. However, you should seek medical advice before buying it as it's rarely recommended nowadays. For all other antimalarial tablets, you'll need a prescription from your GP. Read more about antimalarial medication , including the main types and when to take them.
You must seek medical help straight away if you become ill while travelling in an area where malaria is found, or after returning from travelling, even if you've been taking antimalarial tablets. Malaria can get worse very quickly, so it's important that it's diagnosed and treated as soon as possible. If you develop symptoms of malaria while still taking antimalarial tablets, either while you're travelling or in the days and weeks after you return, remember to tell the doctor which type you have been taking.
