Complete Course of Anti-Malarial Drugs

QUESTION

Hi, I am in Goa and so far have not been bitten by anything. I am taking anti malaria tablets which I do not like. My question is this. If I do not receive any bites do I need to complete the course when I get home?

ANSWER

It is always better to complete the course of anti-malarials, just in case you actually did get bitten but just did not notice it. However, in some cases, the side-effects of anti-malarials can be uncomfortable and unpleasant, so I understand your dilemma. Just remember that there is always a risk of contracting malaria if you stop your anti-malarials early.

Causes of Malaria

QUESTION

What are the causes of malaria?

ANSWER

Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Usually, people get malaria by being bitten by an infective female Anopheles mosquito.

Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken on an infected person. When a mosquito bites an infected person, a small amount of blood is taken in which contains microscopic malaria parasites. About 1 week later, when the mosquito takes its next blood meal, these parasites mix with the mosquito’s saliva and are injected into the person being bitten.

Following the infective bite by the Anopheles mosquito, a period of time (the “incubation period”) goes by before the first symptoms appear. The incubation period in most cases varies from 7 to 30 days. The shorter periods are observed most frequently with P. falciparum and the longer ones with P. malariae.

Because the malaria parasite is found in red blood cells of an infected person, malaria can also be transmitted through blood transfusion, organ transplant, or the shared use of needles or syringes contaminated with blood. Malaria may also be transmitted from a mother to her unborn infant before or during delivery (“congenital” malaria).
