Yellow Fever is a serious but relatively rare tropical disease caused by infection with the yellow fever virus. The virus enters the bloodstream through mosquito bites and can then spread throughout the body. Vaccination is the only effective protection against Yellow Fever. It is given in the form of an injection which gives protection for at least 10 years. The vaccination is effective 10 days after the injection is given.
Information about DTP (Diphtheria, Tetanus and Polio). Persons born after 1950 have almost all received vaccinations as a child. In general a booster-injection is sufficient. Older persons who have not been vaccinated, or where this is not known, should have the full series of three injections.
Hepatitis A is a highly contagious disease which occurs as a childhood disease in tropical countries. Dutch nationals who were born after the war will probably not have experienced the disease. The Hepatitis A virus is transferred through food and is often found in seafood and raw vegetables. Adults can become very ill and take a long time to recover. Vaccination offers very good protection.
Hepatitis B is one of the most serious infectious diseases in the world. It is caused by the Hepatitis B virus. Hepatitis B is transmitted through blood and sexual relations. Hepatitis B is very contagious. A vaccine can be given in a series of three injections. The blood can then be tested to show the level of anitbodies. If this is sufficient then protection is lifelong.
Information about Rabies
Rabies is a viral infection which is always fatal if symptoms are present. The virus is transmitted through infected mammals' salvia (a dog, cat, monkey or other small mammal; bats can also transmit the disease). Humans can be infected if bitten, scratched or licked by an infected animal. The virus penetrates the body through small wounds in the skin or through mucous membranes in the eyes or mouth. The first visible symptoms can appear a few weeks or even several months after infection. If bitten by an animal suspected of having Rabies, you should immediately (and in any case within 1 week) receive treatment with an immunoglobulin. In addition you should be vaccinated. If you are taking a trip where the risk of being bitten is relatively high, for example if you are going trekking or on a cycling-trip, vaccination against rabies is recommended. If you are then bitten you will not need immunoglobulin, which may in any case be difficult to get hold of in developing countries and treatment with additional vaccinations will be sufficient. Discuss with the vaccination clinic whether a vaccination against Rabies is advisable in your individual case.
