Touring overseas, mainly to regions with mostly emergent population, may perhaps have particular health hazards associated with them. For that reason, all those who want to tour abroad, must know about these conditions, regardless of having taken the proper vaccinations and medical courses for touring.
In this article, we are discussing about the health hazards found in South, Southeast and East Asia for tourists. You must read the below information:
The health hazards in these different areas do not vary considerably. But, several forms of diseases may be more general that others in particular countries.
Health Hazards for Tourists
South Asia includes India, Pakistan, Bangladesh and Sri Lanka. Some of the main contagious health hazards for tourists to this region contain malaria, dengue fever, filariasis, leishmaniasis, Japanese encephalitis, leptospirosis, polio, measles, avian influenza (H5N1) and rabies.
Southeast Asia includes Burma, Cambodia, East Timor, Indonesia, Laos, Philippines, Singapore, Thailand, and Vietnam. Some of the main contagious health hazards for tourists to this region contain malaria, dengue fever, chikungunya, filariasis, Japanese encephalitis, plague, avian influenza (H5N1), schistosomiasis, leptospirosis, measles and polio.
East Asia includes China, Hong Kong, Japan, Macau, Mongolia, North Korea, South Korea and Taiwan. Some of the main contagious health hazards for tourists to this region contain malaria, dengue fever, chikungunya, filariasis, Japanese encephalitis, leishmaniasis, plague, tickborne encephalitis, avian influenza (H5N1), measles, schistosomiasis (Schistosoma japonicum), leptospirosis and rabies.
Below is a brief summary of some of the most general contagious diseases that are found in particular regions within South, Southeast and East Asia.
Dengue fever is a contagious disease which is caused by one of four serotypes of a’flavivirus’ that is spread by mosquitoes. Aedes aegypti mosquito is the most harmful one, and it may even lead to rigorous problems for example dengue hemorrhagic fever and dengue shock disorder which are most likely to cause DEATH. Dengue fever is more widespread in metropolitan and semi-urban locales.
Dengue fever symptoms
Avian flu, which is usually recognized as ‘bird flu’, is caused by the H5N1 germ. It is hardly ever found in humans but is extremely fatal. It is observed in both untamed birds and can even affect domestic birds. The disease is spread by making contact with the bird’s feces, saliva or other discharges. This usually takes place in open-air markets where these types of birds are kept in packed and unclean environment.
NOTE: Eating the meat of affected animals does not cause Avain/Bird flu.
The other two more general kinds of ‘encephalitis’ that you must be aware of includes ‘Japanese encephalitis’ and ‘tick-borne encephalitis’. The word ‘encephalitis’ means irritation of the brain. And is generally caused by viruses. ‘Japanese encephalitis’ is caused by a flavivirus (JEV) that is spread by bite of mosquitoes which are carrying the virus in them. Mosquitoes which belong to Culex category are the most dangerous. ‘Tickborne’ encephalitis is also caused by a flavivirus (TBEV) which is spread from the bite of a contaminated tick. Ixodes class tick is the most dangerous in its class
‘Chikungunya’ is a viral disease. W
Aedes aegypti mosquito
‘Filariasis’ is a sponging/parasitic disease that mostly influences the lymphatic system of humans. This disease is caused by a kind of parasitic worm named ‘nematode’. The major filarial nematodes are Brugia malayi, Wuchereria bancrofti, and Brugia timori. This viral disease is spread from the bite of numerous different class of mosquitoes. It is ‘asymptomatic’ originally and for that reason remains undiagnosed for quite some time. This disease causes extended damage to the lymphatic system.
‘Leishmaniasis’ is a disease, which is caused by one of the several kinds of Leishmania group of protozoal fleas that are spread from the bite of ‘sand flies’. This disease can sometimes be spread because of blood exchange or when ‘IV’ medicine users share their needles. There are mainly 2 kinds of ‘leishmaniasis’, one is cutaneous leishmaniasis (CL) and another is visceral leishmaniasis (VL). ‘Cutaneous leishmaniasis’ is mostly sheltered to the skin and is the more general form. The latter may perhaps affect any organ in the human body.
‘Malaria’ is an infection, which is caused by a disease with the Plasmodium class of protozoal parasites and spread by mosquitoes. Malaria is one of the main health hazards found in the regions of South, Southeast and East Asia. It is spread through the bite of the infected ‘female Anopheles mosquito’. This disease devastates ‘red blood cells’ at a rapid rate, while it also influences the cells of different organs all over the body.
NOTE: If no proper vaccination given to the affected person, he/she may die. Particular treatments may perhaps provide temporary protection/relief but the solution is to reduce the contact to mosquitoes.
‘Rabies’ is a contagious disease caused by the ‘Lyssavirus’ which is spread from animals. It may perhaps penetrate the human mass through the saliva of an infected animal, typically because of a bite. This disease is observed all over the world and is generally spread through dog and bat bites, albeit may other animals may perhaps also be infected. Immunization of animals against ‘rabies’ has been a successful method to lessen the diffusion but there is still a BIG hazard associated with it.
Numerous Rabies Virions
Leptospirosis is an infection with the Leptospira bacteria which may be contracted through cuts in the skin caused by certain animals like rats, skunks, raccoons, foxes and other vermin. It can also be passed on through contact with impure water and soil that may perhaps also penetrate through the mucous membranes in the body and conjunctiva. Less likely it takes place because of bites or transmission from one human to another. Following the severe contagious period, leptospirosis may cause septicemia which can be deadly.
Plague is an infection caused by the ‘Yersinia pestis’ bacteria that is transmitted though fleas. It is more likely associated with the bites of infected fleas on rodents.
The infection is not widespread these days but was conscientious for the deaths of around one-3rd of the European residents in medieval period when it was recognized as the ‘Black Death’. Basically the microorganisms multiples within particular kinds of invulnerable cells and then transmits all over the body through the blood flow. This disease is easily cured but can be deadly if remain uncured.
