Sexually transmitted diseases Sexually transmitted diseases including HIV are acquired through casual sex and contact with commercial sex workers during travel. The only absolute protection is abstinence and the avoidance of alcoholic intoxication. The proper use of the condom gives good but not absolute protection. Many diseases in developing countries are borne by insects including malaria for which the mosquito is the vector. Prevention of insect bites through the use of insect repellents and other measures are necessary in addition to taking anti-malaria pills.
Vaccines are available against mosquito-borne diseases like yellow fever and Japanese encephalitis.
In general, we advise that you consult your doctor at least 4-6 weeks before you leave to give yourself time to complete the vaccinations and allow the body time to make protective antibodies. The lead time also allows the doctor to identify patients with side effects to anti-malaria pills and switch to alternatives. All rights reserved.
