Since January 2011 I got three times malaria. Is it come regularly? Last week also I got maleria and I took medicine but still I have mild headache and sweating feeling tiredenes in between..
The timing of the repeated malaria episodes you have experienced means that it could be recrudescence (where treatment does not completely kill all the malaria parasites in your blood), relapse (where the malaria goes dormant in your liver, then comes back—this is only caused by Plasmodium vivax and Plasmodium ovale malaria) or even re-infection.
However, first of all, the most important thing is to make sure you are properly diagnosed with malaria and secondly, that you receive the right type of treatment for the kind of malaria that you have.
The symptoms of malaria are very general (fever, chills, nausea, tiredness, aches) and can also be caused by many other illnesses and diseases. As such, in order to confirm you actually have malaria, you should have a blood test (thick and thin blood smear, looked at under the microscope by a trained technician, or a rapid diagnostic test (RDT). In some places you can buy these RDTs from local pharmacies and do the test yourself at home).
Depending on where you live, there may be different types of malaria present; in this case, if you do have malaria, it is important to find out which one you have.
P. falciparum is the most common kind in sub-Saharan Africa and first-line treatment is an artemisinin-based combination therapy, such as Coartem – most areas have P. falciparum that is resistant to chloroquine, so this is not appropriate as treatment, nor are sulfadoxine and pyrimethamine combinations (such as Fansidar).
If you have P. vivax or P. ovale, chloroquine may be used, again depending on where you are and whether resistance is known from your area or not. In addition, you might also talk to your doctor about taking primaquine to prevent future relapse and recurrence of the infection.
Repeated re-infection can be prevented by protecting yourself more thoroughly against getting bitten by an infected mosquito. For example, you should sleep under a long-lasting insecticide treated bednet, screen your windows and doors and wear long-sleeved clothing at night and in the evenings. Indoor residual spraying, which coats your walls with insecticide, can also prevent mosquitoes from persisting inside your home.
