For most people, symptoms begin 10 days to 4 weeks after infection, although a person may feel ill as early as 7 days or as late as 1 year later.

Two kinds of malaria, P. Most people, at the beginning of the disease, have fever, sweats, chills, headaches, malaise, muscles aches, nausea, and vomiting. Malaria can very rapidly become a severe and life-threatening disease. The surest way for you and your health-care provider to know whether you have malaria is to have a diagnostic test where a drop of your blood is examined under the microscope for the presence of malaria parasites.

If you are sick and there is any suspicion of malaria for example, if you have recently traveled in a country where malaria transmission occurs , the test should be performed without delay.

CDC has a list of all the places in the world where malaria transmission occurs and the malaria drugs that are recommended for prevention in each place. Many effective antimalarial drugs are available. Your health-care provider and you will decide on the best drug for you , if any, based on your travel plans, medical history, age, drug allergies, pregnancy status, and other factors.

To allow enough time for some of the drugs to become effective and for a pharmacy to prepare any special doses of medicine especially doses for children and infants , you may need to visit your health-care provider weeks before travel. Other malaria medicines only need to be started the day before travel and so last-minute travelers can still benefit from a visit to their health-care provider before traveling.

The drugs used to prevent malaria have been shown to be safe and well-tolerated for long term use. Anyone who goes to a country where malaria transmission occurs should take precautions against contracting malaria.

During the time that you have spent in the United States, you have lost any malaria immunity that you might have had while living in your native country. 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. Several good antimalarial drugs are available, and should be taken early on. The most important step is to go see a doctor if you are sick and are presently in, or have recently been in, an area with malaria, so that the disease is diagnosed and treated right away.

Malaria can be cured with prescription drugs. The type of drugs and length of treatment depend on the type of malaria, where the person was infected, their age, whether they are pregnant, and how sick they are at the start of treatment. Very rarely. Travelers who are taking effective malaria preventive drugs but who will be traveling for an extended period of time or who will be at higher risk of developing a malaria infection may decide, in consultation with their health-care provider, to take along malaria treatment medication referred to as a reliable supply in case they develop malaria while traveling.

If the traveler develops symptoms of malaria, they should immediately seek medical attention so that they can be examined and diagnosed appropriately. If they are diagnosed with malaria, they will then already have with them a reliable supply of an effective malaria treatment medicine to take. Malaria self-treatment should begin right away if fever, chills, or other influenza-like illness symptoms occur and if professional medical care is not available within 24 hours.
