Although the weather is getting cold,  some districts in Macao are still affected by mosquitos. If we travel to tropical regions in Christmas break, we have to be extra careful with mosquitos too. Therefore we have featured Malaria in the round.

What is malaria?

Malaria is a mosquito-borne infectious disease affecting humans and other animals caused by parasitic single-celled microorganisms belonging to the Plasmodium group.

Clinical features

Symptoms of malaria include intermittent fever, chills, sweating, headache, tiredness, poor appetite and muscle pain. In typical cases, the fever comes, then subsides for 1-3 days and then comes again in a cyclical pattern. Complications include anaemia, liver and kidney failure, seizures, mental confusion, coma, and death if the disease is not treated promptly.


You can lower your risk of having MALARIA:

  1. By avoiding the bite of mosquito is the first line and the best defense against contracting malaria.
  2. There is no vaccine against malaria though development of malaria vaccine is underway. If you travel to areas where malaria is common, consult your doctor beforehand for preventive measures and obtain anti-malarial drugs for prophylaxis if necessary. The commonly used drugs include chloroquine, proguanil, mefloquine, doxycycline and malarone. The choices are based on the particular destinations you are going to visit, the risks as determined by your travelling behaviour and your previous health status. They should only be taken after consulting a doctor. If you decide to take such medication you should start it before the trip, continue throughout the trip and after leaving the malarious area according to the instruction of the doctor.
  3. During your visit abroad or after coming back to Macao, if you have symptoms of malaria, seek medical advice immediately and inform the doctor of the places you have visited.
  4. Pregnant women should try to avoid going to areas where malaria is endemic.



There are effective drugs against malaria but early diagnosis and prompt treatment are crucial. The doctor would prescribe a course of anti-malarial drugs with other supportive measures. The patient should complete the whole course of medication to ensure clearance of the malaria parasites.
