is required for pilgrims going to Mecca. Detailed information is available on the CDC site. Malaria prevention consists of preventing or reducing exposure to mosquitos by using screened rooms, air-conditioning, and nets, and use of repellents (usually DEET). In addition, chemoprophylaxis is started before travel, during the time of potential exposure, and for four weeks (chloroquine, doxycycline, or mefloquine) or seven days (atovaquone/proguanil or primaquine) after leaving the risk area. Medication kit The traveler should have a medication kit to provide for necessary and useful medication. Based on circumstances, it should also include malaria prophylaxis, condoms, and medication to combat traveler's diarrhea. In addition, a basic first aid kit can be of use. Studies have shown there are four main medical problems that travellers develop—diarrhoea or gut problems, respiratory problems, wounds and pain. The medical kit should at least address these common things. Research has also shown that the best treatment for travellers diarrhoea is to take an antibiotic (e.g. ciprofloxacin) plus a stopper (e.g. loperamide). Due to bacterial resistance, different parts of the world require different antibiotics. It is best to consult a travel doctor to sort out the best medical kit for the exact destination and medical history of the person travelling.
