5 'extremely dangerous' diseases can be deadly

When global warming, scientists warned of potentially dangerous problems such as melting ice, rising sea levels and extremely harsh weather . There is still another threat emerging, which is the " strange " new diseases spreading in places that are considered safe.

Melted permafrost can cause " scary pathogens ", while warming temperatures will help insects carry the disease to spread far and wide. Here are 5 " extremely dangerous " diseases that can be lethal:

1. Anthrax (Anthrax)

In late July 2016, an anthrax outbreak returned to the reindeer herds in Siberia, killing more than 2000 children. Some people there also suffer from this disease. According to local officials, who is the " main culprit "? 75 years ago, a reindeer died in the frozen ground. Until summer, when the temperature warms again, the frozen soil melts and the dead body inside is also discovered.

George Stewart - a bacteriologist who studied at the University of Missouri's Veterinary Department, replied to Live Science, saying: " Anthrax is an acute bacterial infection, it originates from animals spread to humans caused by anthrax. The infectious spore is covered by a protein shell that can keep it safe in the animal body 'temporarily dying' in the soil layer for centuries . "

Over the years, researchers have argued that Siberia's burying ground for cattle and carcasses has been enough to trigger new epidemics as the frozen ground of Siberian people melts.

2. Zika virus

Zika - a typical virus that does not cause any symptoms or only mild fever and rash in adults but is very dangerous when infected with pregnant women, causing miscarriage and microcephaly in the fetus. The main organisms that cause Zika disease are caused by the bite of an infected Aedes mosquito, carrying dengue fever and Chikungunya fever .

According to the Centers for Disease Control and Prevention, A. aegypti is a mosquito species that usually burns during the day, reproducing quickly in rainwater bottle caps. Currently, most of these mosquitoes are found in tropical regions, especially in South and Central America, Southeast Asia, Africa and the United States , but are more limited in the southeastern states.

The earth is getting warmer, so diseases that are contagious are spreading. A 2014 article in the journal Geospatial Health wrote: " Some tropical regions are rarely visited by the A. aegypti, while the supposedly safe places are now as inland Australia and the south. Iran, the Arabian Peninsula and many parts of North America only have 'friendly' mosquitoes . "

According to the Intergovernmental Panel on Climate Change, the reason we think: " How the spread of A. aegypti is not the cause of haemorrhagic disease and other diseases in the region. temperate climate, while many developed countries can control mosquitoes on the spot.

According to a joint stock company studying the atmosphere, even simple tools such as window blinds can be used to prevent this disease. On the other hand, areas that are affected by global warming that cause drought can show a rapid increase in mosquito A. aegypti. Because people here often catch rainwater in the yard to use and water containers will be a convenient place for mosquitoes to breed.

3. "Dead body" disease

Anthrax is a pathogen that lies hidden beneath the frozen soil. In 2015, researchers introduced a " giant " virus that they discovered in Siberia's permafrost, which needs to be able to infect after 300,000 years. Fortunately, the virus only infects amoeba without harming humans, but their existence raises many concerns that: " Deadly pathogens like smallpox or unknown viruses are extinct." or may not be hidden in the permafrost . "

Human activities such as oil drilling and mining in the frozen areas of Siberia could previously affect the millennium's " sleep " of microorganisms.

4. Diseases spread by ticks

According to an article in the Infectious Disease Clinics of North America magazine : "Like mosquitoes, ticks have found a new habitat like warm climate and on the move, they are causing us very much. A good example is Babesiosis - a rare disease - caused by a parasite that infects red blood cells, which is found mainly in the Northeast and above the Midwest. In addition, the disease is mainly transmitted in the summer when the ticks and humans are most active, and the hot and longer summers are likely to be a good opportunity for the bacterium Babesiosis to transmit. growing ".

Similarly, Lyme disease can also spread to other areas in the North. In a 2008 article in Ecohealth magazine, " The tick is the Lyme disease-causing organism, predicted by 2080 it will be present in 213% of Canada's living environment if climate change continues to move. move along its trajectory ". The researchers concluded: " Mites can move out of the southern United States and the number will increase greatly in the center of the country."

5. Cholera cholera

Cholera diarrhea can be fatal because of contaminated water. The next time, when the earth gets warmer, researchers think that cholera outbreaks may rise.

A study presented in 2014 at the annual meeting of the American Geophysical Union found that: " The increase in temperature and flooding caused by climate change may be the cause of disease. cholera epidemic in areas is increasing due to poor sanitation . " Researchers say: " Flooding can spread contaminated water to nearby areas, while drought-prone areas are often concentrated in cholera bacteria (Vibrio cholera bacteria) in these areas. Small waters, although the two environmental conditions are different, they are harmful to public health .

David Morens - senior scientific advisor at the Institute of Allergy and Infectious Diseases said at Think Progress in 2015: " I put cholera at the top of the list of diseases that made me most worried when Climate change is suitable to develop in warm weather areas. So when the Earth warms, the water will warm up, it will be more favorable for it to develop and climate change will make the disease much worse . "
