How do you catch malaria?

Malaria is caused by the plasmodium parasite. This is carried by mosquitoes, and is transferred to humans through bites. Once in the bloodstream, the disease spreads by infecting other cells. Symptoms can manifest at any time for up to three months after infection, or even longer in rare cases. These include fever, headache and flu-like signs in some cases, but an aggressive strain may cause organ failure, and even prove fatal, so it is important to take precautions.

How many travelers get malaria?

It is estimated that as many as 1,500 British travellers have contracted the illness during recent years. The condition is also noted for its ability to adapt to and resist certain forms of medication and vaccines. For this reason, it is essential to research the area you are travelling to well in advance, and find out which strains may be present. This will affect the type and course of treatment you use.

How does Lariam work?

Lariam is a branded medication manufactured by Roche. It contains a functioning component called mefloquine hydrochloride, which targets the parasite and stops it from reproducing. This product is adept at tackling the parasites present in regions where the disease has developed an immunity to other antimalarials, such as chloroquine. It can also be used to treat active instances of the condition, but this will need to be done under the supervision of a doctor.

There are several different strains of malaria, so before you travel, you will need to check which antimalarial medication you should take, to ensure that the treatment you have is suitable for the area you are visiting. Your GP or local travel clinic will be able to provide further advice.
