The synthesis of viruses can be harmful to humans. How to prevent and treat

 1. Marburg Virus

                                                                
                                                                                 Illustration of the Marburg virus.

According to the World Health Organization (WHO), the Marburg virus was first identified by scientists in 1967, when small outbreaks occurred among laboratory workers in Germany. They contracted the virus after coming into contact with monkeys from Uganda. 

According to the Mayo Clinic, the symptoms of the Marburg virus are similar to Ebola in that both can cause dengue fever. Infected people will have a high fever and bleeding throughout the body leading to shock, organ failure and death.

The death rate in the first outbreak in 1967 was 24%, but rose to 83% during the 1998-2000 outbreak in congo and 100% during the 2017 outbreak in Uganda, according to the WHO.

2. Ebola virus

In 1976, the first known ebola outbreak in humans occurred simultaneously in Sudan and congo. Ebola is spread through blood or other bodily fluids, or the tissues of an infected person or animal.

Ebola virus expert Elke Muhlberger, an associate professor of microbiology at Boston University, said different strains have different levels of danger.

According to Essential Human Virology (2016), the Reston Ebola virus does not even make people sick, but the Bundibugyo strain has a mortality rate of up to 50% while the Sudan strain reaches 71%.

3. Rabies virus

Although the pet rabies vaccine has made the disease extremely rare in developed countries, it remains a serious problem in India and some parts of Africa.

We become infected with rabies virus after being bitten or scratched by an animal with rabies. It affects the brain and nerves.

According to the National Health Service (NHS), once symptoms begin to appear, death almost always occurs afterwards.  

Muhlberger said that if left untreated, the chances of dying are 100%

4.HIV

The HIV virus (green) is infecting a cell.

Today, the most dangerous virus appears to be HIV. An estimated 32 million people have died from HIV since it was first discovered in the early 1980s.

Powerful antiretroviral drugs have helped people with HIV extend their lives, but the virus is still wreaking havoc on many low- and middle-income countries that account for 95 percent of new HIV infections.

Nearly one in 25 adults in Africa is HIV positive, according to the WHO. In 2020, there were 680,000 HIV-related deaths worldwide.

5.Dengue virus

The dengue virus first appeared in the 1950s in the Philippines and Thailand, and since then, it has spread throughout tropical and subtropical regions across the globe, according to Clinical Microbiology Reviews.

According to the journal Nature, up to 40% of the world's population lives in areas where dengue fever is endemic. The disease is likely to spread further as the Earth warms.

The WHO says about 100-400 million people get dengue fever each year with a lower mortality rate than some other viruses. The dengue virus can cause an Ebola-like disease called dengue fever, which has a mortality rate of 20% if left untreated.

6.Virus SARS-CoV

Sars-CoV was first identified in 2003 during an outbreak in China. SARS then spread to 26 countries around the world, infecting more than 8,000 people and killing more than 770 in a matter of months, according to History.com.

According to the CDC, SARS causes fever, chills, body aches and pains and often progresses to pneumonia — a severe condition that causes the lungs to become inflamed and filled with pus. The virus has an estimated mortality rate of 9.6%.

7.Virus SARS-CoV-2

SARS-CoV-2 was first identified in December 2019 in Wuhan, China. The virus can originate from bats and be transmitted through intermediate animals before infecting humans.

Since its inception, the virus has caused more than 5 million deaths worldwide.

According to who, SARS-CoV-2 causes COVID-19. Symptoms include fever, cough, loss of taste, loss of sense of smell, shortness of breath, chest pain and loss of mobility.
