Without frequent exposure to malaria parasites, your immune system has lost its ability to fight malaria. Please consult with your health-care provider or a travel clinic about precautions to take against malaria preventive drugs and protection against mosquito bites and against other diseases. Buying medications abroad has its risks. The drugs could be of poor quality because of the way they are produced. The drugs could contain contaminants or they could be counterfeit drugs and therefore may not provide you the protection you need against malaria.
In addition, some medications that are sold overseas are not used anymore in the United States or were never sold here. These drugs may not be safe or their safety has never been evaluated. It would be best to purchase all the medications that you need before you leave the United States.
As a precaution, note the name of the medication s and the name of the manufacturer s. That way, in case of accidental loss, you can replace the drug s abroad at a reliable vendor. Attempts at producing an effective malaria vaccine and vaccine clinical trials are ongoing.
The malaria parasite is a complex organism with a complicated life cycle. The parasite has the ability to evade your immune system by constantly changing its surface, so developing a vaccine against these varying surfaces is very difficult. In addition, scientists do not yet totally understand the complex immune responses that protect humans against malaria.
However, many scientists all over the world are working on developing an effective vaccine. Because other methods of fighting malaria, including drugs, insecticides, and insecticide-treated bed nets, have not succeeded in eliminating the disease, the search for a vaccine is considered to be one of the most important research projects in public health.
Yes, but not all types of malaria drugs. Children of any age can get malaria and any child traveling to an area where malaria transmission occurs should use the recommended prevention measures, which often include an antimalarial drug.
However, some antimalarial drugs are not suitable for children. CDC advises women who are pregnant or likely to become pregnant not to travel to areas where malaria transmission occurs, if possible. Malaria in pregnant women can be more severe than in women who are not pregnant. Malaria can increase the risk for serious pregnancy problems, including prematurity, miscarriage, and stillbirth.
If travel to a malarious area cannot be postponed, use of an effective chemoprophylaxis regimen is essential. However, no preventive drugs are completely effective. Please consider these risks and other health risks as well and discuss them with your health-care provider.
Because there is no evidence that chloroquine and mefloquine are associated with congenital defects when used for preventing malaria prophylaxis , CDC does not recommend that women planning pregnancy need to wait a specific period of time after their use before becoming pregnant.
However, if women or their health-care providers wish to decrease the amount of antimalarial drug in the body before conception, the below table provides information on the half-lives of selected antimalarial drugs. There are limited data available about the safety of antimalarial drugs while breastfeeding. However, the amount of antimalarial drug transferred from the nursing mother to her infant is not thought to be harmful to the infant.
Very small amounts of the antimalarial drugs chloroquine and mefloquine are excreted in the breast milk of women who are breastfeeding. Although there is limited information about the use of doxycycline in breastfeeding women, most experts consider it unlikely to cause any harm.
No information is available on the amount of primaquine or tafenoquine that enters human breast milk. The mother and infant should be tested for G6PD deficiency before primaquine is given to a woman who is breastfeeding.
Because there is no information on the use of tafenoquine in infants, tafenoquine is not recommended during breastfeeding. It is not known whether atovaquone, which is a component of the antimalarial drug Malarone, is excreted in human milk. Proguanil, the other component of Malarone, is excreted in human milk in small quantities.
Based on experience with other antimalarial drugs, the quantity of drug transferred in breast milk is not likely to be enough to provide protection against malaria for the infant. You and your family can most effectively prevent malaria by taking all three of these important measures:. Any traveler who becomes ill with a fever or flu-like illness while traveling, and up to 1 year after returning home, should immediately seek professional medical care. You should tell your health-care provider that you have been traveling in an area where malaria transmission occurs and ask to be tested for malaria infection.
It depends on what areas of that country you visited, how long ago you were there, and whether you ever had malaria. In general, most travelers to an area with malaria are deferred from donating blood for 1 year after their return. People who used to live in countries where malaria transmission occurs cannot donate blood for 3 years. People diagnosed with malaria cannot donate blood for 3 years after treatment, during which time they must have remained free of symptoms of malaria.
Blood banks follow strict guidelines for accepting or deferring donors who have been in malaria-endemic areas. They do this to avoid collecting blood for transfusions from an infected donor. In the United States during the period , there were 97 cases reported to CDC where people acquired malaria through a transfusion.
Because of these control measures, transfusion-transmitted malaria is very rare in the United States and occurs at a rate of less than 1 per million units of blood transfused. The disease should be treated early in its course, before it becomes serious and life-threatening. Without prompt treatment, this type could lead to you quickly developing severe and life-threatening complications, such as breathing problems and organ failure. Seek medical advice immediately if you develop symptoms of malaria during or after a visit to an area where the disease is found.
You should still seek medical help even if it's several weeks, months or a year after you return from travelling. Page last reviewed: 22 August Next review due: 22 August The initial symptoms of malaria are flu-like and include: a high temperature of 38C or above feeling hot and shivery headaches vomiting muscle pains diarrhoea generally feeling unwell These symptoms are often mild and can sometimes be difficult to identify as malaria.
You may be prescribed medications to prevent the disease. These medications are the same as those used to treat the disease and should be taken before, during, and after your trip.
Talk to your doctor about long-term prevention if you live in an area where malaria is common. Sleeping under a mosquito net may help prevent being bitten by an infected mosquito.
