Four Viruses For Which No Vaccine Has Yet Been Discovered

Millions of people around the world are waiting for the vaccine to cure the corona epidemic. Experts warn that no matter how fast the vaccine development process may take time, it may take time and the vaccine may not be discovered if the situation worsens.

“We may have to deal with this virus,” said Michael Ryan, director of a health emergency at the World Health Organization (WHO).

However, the chances of living with the virus can be devastating. About 7 million people have been affected so far and more than 400,000 people have died from the infection.

The search for a vaccine can go on for years or decades.

These efforts may be wasted and may yield good results, as seen in the case of Ebola.

Ebola was first reported in 1976. At the time, the death toll was 50 percent. As of the beginning of this year, no vaccine had been developed. The World Health Organization and some other countries have finally approved a vaccine to prevent it.

But here are four other deadly viruses that have not yet been vaccinated.

HIV-AIDS

It has been more than thirty years since the HIV virus was discovered. AIDS is caused by the HIV virus. According to the World Health Organization, 32 million people worldwide have been diagnosed with AIDS so far.

HIV has a significant impact on people’s lifestyles. People have been forced to change their sexual habits because the main cause of HIV infection is sex.

Early cases of AIDS were found in gay people. That’s why the disease was associated with a sense of stigma. In some parts of the media, it has also been called ‘gay cancer’

Today, almost four decades later, no medicine has been developed. Forty million people worldwide have been affected.

The virus’s elimination seems to be far away.

However, it can be avoided by caution and treatment can reduce its impact so that the affected person can live a normal life.

Recently, two cases have been reported in which HIV-infected people were treated with stem cells. Experts warn that the treatment can be dangerous and cannot be tested in all cases of HIV infection.

Avian Influenza

Two types of avian influenza have been reported since the late 1990s and many people have died from the infection.

The virus is transmitted to humans by the waste of birds. H5N1 virus was first detected in Hong Kong in 1997. This led to the mass killing of chickens there.

So far, the virus has reached more than 50 countries in Africa, Asia, and Europe. The death rate from this virus is 60%. In May 2013, the H5N1 virus was detected in China, where various cases of H. pylori infection were reported.

According to the WHO, a total of 1,565 infections were reported between 2013 and 2017, of which 39% died.

The spread of the virus from human to human is unusual, according to the World Health Organization. Once proven, it’s easy to stop.

SARS

SARS is a kind of coronavirus. It was first revealed in 2003. Based on the discovery of the so far, it is believed that it came from the skins of man.

The first case of the infection was reported in 2002 in the Chinese province of Guangzhou. The virus causes severe difficulty breathing. In 2003, more than 8,000 people in 26 countries were affected.

Since then, fewer cases of infection have been reported.

Unlike avian influenza, the virus is transmitted primarily to humans. This is the reason for the high incidence of infections in health centers because no significant precautions were taken to prevent it.

According to the World Health Organization, as soon as precautionary measures were taken to prevent the infection, the infection stopped in July 2003.

There were more than 8,400 cases of the virus, in which 916 people died. The death rate is 11%.

MARS

MARS is also a type of coronavirus. It was first revealed in 2012. It causes a disease called MARS. The disease has a high mortality rate. By November 2019, 2,494 people worldwide had been infected with the virus, and 858 of them had died.

The virus was first reported in Saudi Arabia but has since been found in 27 countries. These include 12 countries in the Middle East.

According to the World Health Organization, countries outside the Middle East, where these infections have been found, have actually come from the same region.

The virus is mainly transmitted from animals to humans. The Arabian camel is thought to be the primary source of the virus.

Human-to-human infection is rare. Efforts to develop the vaccine were postponed after the situation in both MARS and SARS was brought under control.
