Some general health tips while travelling, anywhere

Take a medical kit
Practice safe sex
Be careful what you eat and drink – avoid uncooked foods and salads, peel your own fruit, be suspicious of buffet style meals, if the water in the country is unsafe to consume, so is the ice in your drink.
Make sure your vaccinations are current
Limit your consumption of alcohol to safe levels
Avoid close contact with animals, including domestic pets
Use mosquito repellent and take anti-malarial medication if in a malarial area
Be especially careful when driving
Protect yourself from overexposure to the sun
Ensure that you have enough medical and personal essentials to last the trip. In some countries the supply of feminine hygiene products and condoms may be unreliable.
Use medicated hand wash before eating.
Get adequate rest during your travels
AND MOST IMPORTANT – take out adequate travel insurance.
