The 12 deadliest viruses in human history
By the way, scientists have identified millions of types of viruses, but scientists have confirmed 12 of these viruses as deadly viruses.
1) Marburg virus:
It was first discovered in 1967 when some German scientists were experimenting on infected monkeys brought from Uganda. The virus was transmitted from monkeys to scientists. Symptoms include meningitis, hemorrhage, which eventually leads to shock, organ failure, and death.
2) Ebola virus
The virus first appeared in Sudan and Congo in 1976. Mortality rates range from 50 to 71 percent. The virus is spread by exposure to the infected person’s blood or other body fluids.
The rabies vaccine almost completely eradicated the virus from developed countries in 1920, but it is still present in India and parts of Africa. The virus is spread by the bite or injury of an infected animal. According to the National Health Service (NHS), once infected with the virus, death is almost certain.
4) HIV (AIDS)
This is probably the most dangerous virus in the world today. More than 320 million people have lost their lives since the discovery in 1980. Sadly, no vaccine has yet been developed for this virus, and there is no cure for it.
5) Small packs
In 1980, the World Health Organization (WHO) declared the world free of smallpox, but before that one in every three victims had to die. And those who recovered from it developed chronic medical problems, including loss of sight.
The virus is spread by rat waste. Within a few days, the victim develops severe breathing difficulties, which can lead to death. The virus has so far killed 600 people in the United States.
The influenza virus caused the worst epidemic in human history, also known as the Spanish flu. The epidemic broke out in 1918 and consumed 40% of the world’s population.
Dengue has been reported in the Philippines and Thailand. According to Clinical Microbiology Reviews, 40% of the world’s population currently lives in places that are severely affected by dengue. About 100 to 400 million people are infected with dengue every year.
There are 2 rotavirus vaccines available to protect children. It is the leading cause of diarrhea in newborns. In developed countries, it is now rare for a child to die from the virus, but in developing countries it is still a major problem because in such countries there are medical means to compensate for the dehydration of children during the disease. Are very limited.
The virus, which can severely affect respiratory respiration and cause pneumonia, emerged in 2003. The epidemic began in China and spread to 26 countries. 8,000 people were affected and more than 770 people died in just a few months.
11) SARS-CoV2 (coronavirus)
The virus, belonging to the Sarsco family, became the epicenter of the epidemic in China, forcing authorities to shut down the entire province and surrounding cities, but in a short time it spread to almost every region of the world. Its symptoms are similar to those of the stork, but the death toll has risen to more than 5 million.
12) Mers Kovo
The virus spread to Saudi Arabia in 2012, then to South Korea in 2015. The virus is also linked to the coronavirus and the stork cobra. According to the WHO, camels are the first to be infected with the virus, after which it is transmitted to humans. Symptoms include fever, cough, and difficulty breathing.
