Tourists may be exposed to certain diseases when they travel to tropical, tropical or Latin American countries, such as diarrhea, malaria and dengue fever. You must therefore learn about vaccines before traveling to these areas.
Although vaccines are not available for all dangerous diseases, taking precautions is a useful precautionary measure before traveling.
The German Institute Robert Koch stressed that tourists should receive the advice of a specialist in tropical medicine at least five weeks before they can be vaccinated in time.
There is no single vaccination for all travel-related illnesses, so elderly tourists, pregnant women, diabetics and people with chronic illnesses should consult their doctor about their trip. Travelers from the tropics should also be aware of the following diseases:
1- Travel diarrhea
According to Professor Frank Mockenhaubt of the Institute of Tropical Medicine at Charette Hospital in Berlin, Germany, travel-related diarrhea is one of the most common diseases. In addition, nearly a third of travelers travel to Africa, Asia or Latin America.
Diarrhea can be caused by a variety of pathogens and the symptoms often disappear within a few days without any complications.
Once symptoms are present – such as fever or stomach and intestinal cramps – the doctor should take a stool sample to identify the cause of the disease.
In order to avoid any infection, avoid the ingestion of uneaten or unsweetened foods, it is best to drink water from closed bottles without using ice cubes, as well as from wash hands thoroughly and repeatedly.
2 – Hepatitis "all"
The hepatitis A virus is spreading worldwide and the Robert Koch Institute has reported an increase in its incidence of 40 to 50% during travel over the last 10 years.
The virus is transmitted primarily through the supply of water and contaminated food. The German Institute recommends pre-vaccination in areas where the virus spreads, not only in the tropics, but also in the Mediterranean and Mediterranean countries. Eastern Europe.
3. malaria
German Professor Frank Mockenhaubt said that malaria is a serious disease if you ignore it and that it can be easily treated and cured quickly if it is detected in time.
It is best to wear long, loose clothing in the dark when mosquitoes activate the wearer, and spray a mosquito-activated spray that activates the night.
When traveling to certain countries, consult a specialist in tropical medicine. It may be useful to take preventive tablets for malaria and there is always a trade-off between the side effects and the risks of malaria.
The preventive use of the disc is limited to travel to high-risk areas, such as sub-Saharan African countries.
There is still no vaccine approved for malaria.
4- dengue
Dengue fever is transmitted by active mosquitoes during the day and is common in Southeast Asia, Africa, India, Central America and South America.
Symptoms often occur two to 10 days after mosquito bites, and symptoms of dengue and influenza, including severe fever, joint pain, and severe headaches, are often confusing.
When such symptoms appear, it is best to consult a doctor immediately and consult a doctor specialized in tropical medicine in the severe stages of the disease.
Due to the lack of vaccination against dengue, preventive measures must be observed by wearing long clothes and using methods of elimination of mosquitoes.
5- Rabies
Elmer Elzner, director of the Vaccine Office at the German Armed Forces Hospital in Berlin, said rabies remains dangerous in many tropical countries, especially in rural areas.
As the disease is mainly transmitted by dogs, it is advisable for a German specialist in tropical medicine to be vaccinated appropriately before traveling to countries where rabies is endemic, especially in case of close contact with animals. .
If the traveler is bitten by a dog and he has not been vaccinated before, he must go immediately to the hospital, the subsequent prevention being carried out immediately. It is best to be vaccinated 24 hours after the bite of the dog. The vaccine is available in the country of destination.
6 Japanese encephalitis
Japanese encephalitis is transmitted by the bite of some mosquitoes, especially in Asia and can lead to serious complications that can lead to unconsciousness or paralysis, but it rarely worsens.
Tourists wishing to visit the areas affected by the virus or its residents are advised to be vaccinated because there is no effective treatment for Japanese encephalitis.
7- Yellow fever
Yellow fever is a relatively rare disease among tourists. The World Health Organization (WHO) has confirmed that vaccination once provided lifesaving protection against yellow fever, but that vaccination should not be used in people with yellow fever. Or pregnant women.
