Asia - tangible risks from mosquitoes
Since 2013 the bird flu H7N9 in China is a danger to travelers. The disease includes high fever, cough, shortness of breath, and, if necessary, a rapidly progressive, severe pneumonia. In order to minimize the risk of contamination, travelers should avoid contact with poultry and, in the case of known cases of disease, keep distance from infected persons.
In addition, the dengue fever in Asia as well as the Pacific area plays an important role. The main areas of distribution were, for example, India and Nepal. Likewise, the number of cases rose recently in Vietnam and Thailand, which are very popular with German holidaymakers. Also in parts of the Pacific - like the Solomon Islands - the authorities reported more cases. In the South-East Asian region travelers are also confronted with the Chikungunya fever. Here some symptoms resemble the dengue fever - like fever and limb pain - but there are also skin rashes, eye infections and gastrointestinal problems.
The risks on the "Fifth Continent" are far less well known to travelers. In Australia, for example, cases of the so-called Ross River fever occur. Affected areas are, in particular, the federal states of South Australia, Northern Territory, Queensland, Victoria and New South Wales. The disease is also spread by mosquitoes. Comparatively harmless for travelers is presented in the Asia-Pacific region Japan.
Americas: Zika on the retreat - other risks continue
For the American continent, it is necessary to take increased safety precautions against infection by mosquito bites, especially in Peru and Brazil, before the dengue or chikungunya fever or also before malariato protect. Apart from this, traveling to North America is largely unhealthy. The cases of Zika in Florida have recently declined to zero.
In Brazil, the Zikavirus, through which the South American country made headlines in recent years, is also largely on the retreat. Brazil is currently suffering from an increase in yellow fever. Countries such as Argentina, Uruguay, Paraguay and Bolivia are relatively safe for travelers of health.
Africa: malaria cases in the Kruger National Park - rare diseases in Madagascar and Togo
In Central Africa there may be isolated cases of Dengue or Chikungunya. Here, however, other infectious diseases such as malaria or yellow fever are at greatest risk. Malaria plays an important role in South Africa, for example in the Kruger National Park, which is very popular with safari tourists.
The bacterial infectious disease cholera also spreads in Central Africa. It is mostly caused by contaminated drinking water or infected food in the form of a bacterium and leads to severe diarrhea. Cholera often occurs in countries where drinking water and sewage systems are not separated. In addition, fish and other food from rivers and the sea can be contaminated. Among the more touristic countries, Mozambique and Ghana are among the affected areas. In Madagascar last autumn, cases of an almost almost extinct disease occurred with the plague. In the small West African country of Togo, in the spring of 2017, cases of the rare Lassafieber caused diarrhea. It is transmitted by excretion of mice and contaminated foods.
The North African region, outgoing from Morocco and along the Mediterranean coast, is as safe as possible for travelers from a health perspective. No serious epidemics have been recorded in the last 12 months.
On the Arabian Peninsula, or more precisely in the United Arab Emirates or Oman, the danger of being infected with an infectious disease is low.
Europe: measles experiencing sad renaissance
Even in nearby countries, there are risks to be considered. The measles is a highly contagious infectious disease affecting children in particular. In countries with a vaccination obligation or after correspondingly large-scale vaccination campaigns, authorities could largely eradicate the disease. Due to a lack of precaution, however, the disease appears again more frequently, especially in Eastern European countries. In Romania since the end of 2016 thousands of new infections have been registered. Travelers are therefore strongly advised to refresh their own immunization. Recently, it has also become a case of cases in many parts of Italy.
As a matter of principle, however, Europe is still one of the safest destinations in the world due to high hygienic and medical standards.(pm)
