Are there any tropical diseases I should be worried about?
Every year in Belize there are a couple dozen isolated cases of Malaria and Dengue Fever, but these are usually confined to areas of dense jungle near the Guatemala border. 2007 saw a small “outbreak” of about 40 cases of Dengue Fever in Orange Walk and Cayo, but normally Belize does not experience any serious outbreaks of these diseases.
There are no required vaccinations to enter Belize, although most health professionals would recommend you have your Tetanus, Hepatitis A and B shots up to date. The best practice is to consult with medical travel specialists to see what they recommend for the part of the world you will be travelling in.
It is recommended to take anti-malarial medication if you are planning on spending an extended period of time in the remote jungle regions of Belize, otherwise you shouldn’t have to worry about it.
