1 Ebola Virus
The picture
The virus is mainly found in Africa and can be transmitted by physical contact with patients, with a high mortality rate of 50 to 90 percent. Currently, there is no cure for the virus.
Influenza A virus
The virus is the most dangerous flu virus, with a high mortality rate, because it can quickly evolve into new, more virulent and infectious viruses, rendering existing treatments ineffective.
3 HIV
The virus destroys the body’s T lymphocytes, causing people to lose their immunity and die from other diseases. At present, there is no cure or medicine for the virus.
4 Smallpox virus
The picture
It has the highest incidence and death toll of any viral infection, killing at least 150 million people in the 18th century. Fortunately, humans have found a cure for this virus.
5 Rabies virus
The virus is transmitted to humans by animals (dogs, cats, wolves, etc.) and causes human rabies, which has a 100% mortality rate. Rabies can be prevented by vaccination, so it is important for humans to get vaccinated in time after being scratched or bitten by these animals.
6 Hepatitis virus
People infected with the virus are more likely to develop hepatitis, which can lead to cirrhosis or liver cancer.
7 Dengue Virus
The virus, which is spread mainly by mosquito bites, first appeared in the tropics and is now found in many areas, and the outbreaks are getting bigger. For this virus, children under the age of 15 need to pay more attention because they are vulnerable.
8 SARS coronavirus
The virus is a contagious respiratory disease that causes severe acute respiratory syndrome (SARS) and can be spread by droplets in close proximity. His mortality rate averaged 9.6%, with the highest 14-15%.
Marburg virus
The picture
The virus appeared in Marburg, Germany in 19967. It is highly contagious and transmitted by body fluids. The mortality rate is also very high, about 25% to 100%.
10 West Nile virus
The virus is spread by mosquitoes, mainly birds, but can also infect people. But the virus has a relatively small impact on people, with only 0.7 percent dying from encephalitis.
