The high density of populations and insufficient sanitary conditions increases the risk to acquire viral diseases in tropical areas. This holds true for ubiquitous as well as for regional viral infections. Hepatitis and AIDS are found worldwide, but play a dominant role in tropical areas. Classical tropical viral infections are zoonoses. They are primarily infections of nonhuman vertebrates (e.g. rodents) and of arthropod vectors and can be transmitted to man. According to the clinical outcome these viral infections can be divided into three groups: influenza-like disease with arthralgia, encephalitis and hemorrhagic fevers. The majority of infections belong to the first group, followed by encephalitis cases. Viral hemorrhagic fevers are rare in visitors of tropical areas. Antibody detection is the method of choice in the diagnosis of tropical viral infections. In special situations (e.g. Lassa fever) the direct detection of the virus by PCR can be helpful. Tests for the detection of arboviruses, filoviruses and arenaviruses are only performed at a few centers worldwide.
