Everyone entering Kenya must be in possession of a valid International Certificate of Vaccination against yellow fever. It is imperative that you obtain malaria prophylactics before entering Kenya . When purchasing these, please tell your doctor or pharmacist that you intend visiting Kenya . It is important to note that the Kenyan authorities have banned the use of chloroquine combinations as prophylaxis, and instead recommend the use of either mefloquine (Lariam/Mefliam) or doxycycline. Start your course at least one week before entering Kenya and continue taking the pills for six weeks after leaving the country. If you suffer from side effects, try taking your malaria prophylactics at night, after dinner. Precautionary measures that you can take to prevent contact with mosquitoes are: sleeping under a bed net or in room/tent with mosquito proofing (remember to keep the flaps zipped at all times), spraying your accommodation with insecticide, making use of a mosquito repelling lotion or stick and wearing long sleeve clothes, trousers and socks when outside at night. Immunisation against typhoid, tetanus, tuberculosis, polio, & meningococcal meningitis are recommended.

MALARIA                              
If you're travelling to a malaria area, you'll need to take the following precautions:
Apply insect repellent to exposed skin - recommended repellents contain 20%-35% DEET, and there are a number of brands on the market.
Wear long-sleeved clothing and long pants if you're outdoors at night.
Use a mosquito net if your tent or room isn't screened or air-conditioned; and spray insecticide or burn a mosquito coil before going to bed.
Take the malaria tablets recommended for the region you're travelling to, and keep taking them until the course is complete.
British Airways Travel Clinics provide a comprehensive malaria avoidance programme. You can also visit www.malaria.org.za .
If you come down with flu-like symptoms either during, or within four to six weeks after, your visit to a malaria area, seek a doctor's advice immediately.

HEALTH PRECAUTIONS                                 
Besides malaria, there are other insect-borne diseases such as dengue and sleeping sickness. However, these are less common and using the same precautions as you would against mosquito bites, namely long-sleeved clothes and trousers, repellents and mosquito nets, will help prevent them.

In countries where drinking water isn't properly regulated, stick to bottled or boiled water and avoid tap water, water fountains and ice cubes. Ask your travel consultant about the safety of drinking water in the areas you'll be visiting.
Use common sense when it comes to food and beverages. If you're unsure of their origin, don't touch them.
If you're walking, it's best to wear shoes at all times.

AIDS is rife throughout Africa , so if you're planning to have intimate contact with the locals always use condoms to reduce the risk of HIV and other sexually transmitted diseases.
Avoid handling strange animals, especially monkeys, dogs and cats.
Avoid swimming in stagnant water.
