Tropical Illnesses -- Malaria is responsible for more than one million deaths in Africa each year, so it is imperative to take malaria precautions seriously. The threat of infection -- the result of a bite from a disease-carrying mosquito -- is present throughout the country, though the risk reduces at higher altitudes such as the Kenyan Highlands and Nairobi. Besides using prophylaxis medication, such as Malarone or Larium, arm yourself with strong mosquito repellents that can be safely sprayed or rubbed onto exposed skin, and make use of mosquito nets (these are a standard feature of nearly every property we've reviewed in this book) when you retire at night. Mosquitoes generally appear the moment the sun goes down, and just because you cannot see or hear them does not mean that they aren't buzzing around your ankles -- stay alert and do everything in your power to prevent being bitten (even if you have taken medication). Bear in mind, too, that children are more at risk of contracting the disease. Note that prophylactics have intense side effects on a small percentage of people, including forms of psychosis and depression -- it's worth taking the medication a few days before you leave. If you become ill with either a fever or flulike symptoms while traveling -- or up to 1 year after returning home -- you should seek medical attention at once and let your physician know the details of your travel history, along with details of the prophylactics you've been taking. For additional information on malaria, protection from insect bites, and antimalarial drugs, visit the CDC Travelers' Health website at www.cdc.gov/malaria.
Although mosquito bites are responsible for the greatest number of deaths in Africa, HIV/AIDS is obviously a major health concern in both countries, and you should remain cautious of this fact if you intend to have sexual relations with locals or if you come into contact with human blood.
Less prominent, but occasionally reported, risks in Kenya include tick bite fever, Rift Valley fever, typhus (usually the result of a tick bite), African sleeping sickness, plague, and relapsing fever. None of these pose as great a threat as chloroquine-resistant malaria, but it pays to be vigilant and try to protect yourself against bites.
Cholera has been reported in certain parts of Kenya and Tanzania, but you are unlikely to encounter it on safari. Bilharzia or schistosomiasis (which spends part of its life cycle in snails and the other part in humans) is a concern in and around Lake Victoria, so it's best not to swim there or in any other lakes. Rabies is prevalent in Kenya. Avoid touching any feral animals; if you are bitten by a domestic or wild animal, clean the wound immediately and seek medical treatment. This involves taking a vaccine, and the dose depends on whether you have already been vaccinated against rabies -- not necessary for a one-off visit, but it should be considered for lengthy stays in developing countries.
For general information about outbreaks of infectious diseases abroad, consult the website of the World Health Organization (www.who.int/en), and get more health information for travelers from www.who.int/ith/en.
Dietary Red Flags -- Never drink water from any tap unless you have been assured that it is completely safe to do so (and only if the assurance comes from someone you can trust). On the whole, at every single lodge and camp you'll encounter while on safari, you'll be briefed on the quality of the water and whether it's drinkable. Most places will provide bottled or filtered water in your room or tent; this may be free or chargeable. Most food in Tanzania is safe to eat, but be wary of ice in drinks and washed salads and fruits, and always ask where the water has come from. Also avoid reheated food or food that has been sitting around for awhile -- equally relevant to a street stall and a hotel buffet.
Tanzanians are big meat-eaters, but that doesn't mean that vegetarians should go hungry. When making reservations for safari lodges and camps, make your hosts aware of your dietary predilections. You can do this either directly or through your operator or travel agent. Bear in mind that many of these lodges are a great distance away from towns where special foodstuffs can be purchased, so supplies need to be purchased in advance. If there are vegetarian guests, they need to make adjustments to their shopping list ahead of schedule, and you'll enjoy a more exciting culinary experience if you give prior warning.
Bites & Other Wildlife Concerns -- Although unlikely while on safari, there is a chance of encountering snakes, spiders, or scorpions, and on the coast a variety of sea creatures that can sting. Most snakes will clear off before you have a chance to tread on them, and the old tale that snakes are more scared of humans is generally true. The most worrisome snake is the puff adder, considered too lazy to move off when they sense you coming. In the event that you are bitten, stay calm and seek medical assistance immediately. Remember, the majority of snake bites are not poisonous. Spiders and scorpions may be spotted but are unlikely to pose a threat; the general rule is to leave them alone. At the coast, certain tropical sea creatures can inject venom into bathers' feet, which can be very painful. Wear plastic shoes if such creatures are reported in the area.
High-Altitude Hazards -- Altitude sickness can be a risk for anyone heading to altitudes above 3,000m (9,840 ft.) above sea level, so hikers and climbers tackling Mount Kenya and Kilimanjaro should take adequate precautions and prepare properly for the ascent. Symptoms include shortness of breath, nausea, vomiting, headaches, and dizziness. Mild altitude sickness requires rest before ascending higher; severe altitude sickness requires medication and a slow descent in stages. It's best not to attempt a climb if you have a bad cold or chest infection, or within 48 hours of going scuba diving. It's also a good idea not to go straight from the coast to Mount Kenya or Kilimanjaro, but to acclimatize at a midway altitude, such as Nairobi or the foothills around Moshi, for a couple of days.
Sun/Elements/Extreme Weather Exposure -- It can get incredibly hot under the African sun -- particularly in arid and semi-arid areas. Arm yourself with a high-factor sunscreen, a hat that will protect your face, and good sunglasses, and be vigilant to prevent overexposure to the sun. Be especially cautious of children. At the other extreme, many people are surprised by the prevalence of extreme cold in certain parts of the country. Mount Kenya and Kilimanjaro may lie on the equator, but temperatures, particularly at higher altitudes, are freezing. If you're going to climb, you'll need special protective clothing. Temperature fluctuations are known to take travelers by surprise; because the countries are on the equator, the sun disappears rather suddenly (at more or less the same time throughout the year), and nightfall can bring quick temperature changes.
What to Do If You Get Sick Away from Home
While in the tourist areas, you'll have access to good medical facilities. The coast, too, has top-class facilities, which in some cases even offer cosmetic procedures to vacationers. If you are going to more remote regions, be aware that medical facilities (including drugstores) are few and far between. There may be occasional clinics, but these are poorly equipped and may not be able to dispense medicines that you might require. For minor ailments, pharmacists can assist and recommend a doctor, if necessary. Expect to pay for any medical services either upfront or immediately after treatment. If you have international medical insurance, keep the receipts so your company can reimburse you. However, if you become seriously ill and require advanced medical attention or surgery, you should definitely fly home, as local equipment and training standards are still far below those in the West. Your travel insurance should include repatriation to your home country in an emergency. Within Kenya and based at Nairobi's Wilson Airport, the Flying Doctor's Society of Africa (www.amref.org) provides evacuation from remote areas in both Kenya and Tanzania to the nearest hospital. You may want to consider a temporary membership ($50) if you are going off the beaten track, but for the more popular parks and reserves, there are adequate medical provisions in case of an emergency.
