Travel health depends on your pre-departure preparations, your daily health care and the way you handle any medical problem that does develop. While the potential dangers can seem quite frightening, in reality few travellers experience anything more than an upset stomach.

Inoculation is recommended for cholera, typhoid, hepatitis and malaria.

Even though potable water is available in plenty, as a traveller it is advisable to stick to brand bottled water or beverages. If bottled water is not available, try to use only boiled water.

Modern health facilities are available in most of the areas. But sufficient services are available more in urban areas than the rural areas. Medical facilities are expensive but are much cheaper when compared to that of the developed countries.
