Experts found Khosta-2 very similar to Covid-19

After the pandemic generated by Covid-19, the scientific community has deepened its research on these organisms in recent months and there have been several unpleasant surprises.

A group of American researchers from the Paul G. Allen School of Global Health at Washington State University (WSU) has for several years devoted itself to researched possible new viruses and recently found that a variant of SARS-CoV-2 from Russia can infect humans.

According to experts, it is the virus known as Khosta-2, which is a sarbecovirus of the same type that unleashed SARS-CoV-2 covid-19, which became a pandemic. This virus, which is the second discovered in the last two years, unlike the first identified in 2020, is capable of infecting human cells. But that’s not the worst of it.

Although the virus is similar in composition to covid-19, it appears, according to the study written and published by Michael Letko, a WSU virologist in the journal PLoS Pathogens, It is resistant to the serum of the vaccines made to fight covid, so if it reaches people, it could cause another health crisis.

What is Khosta-2 virus?

“Our research further shows that sarbecoviruses circulating in the wild outside of Asia, including in places like western Russia, where the Khosta-2 virus was discovered, also pose a threat to global health and prevention campaigns.” current vaccination against SARS-CoV-2,” explains Michael Letko, author of the study.

According to the scientist “there are groups right now trying to find a vaccine that not only protects against the next variant of SARS-2, but actually protects us from sarbecoviruses in general”considering that there may be many more of this type of virus that are similar to covid but stronger.

“Unfortunately, many of our current vaccines are designed for specific viruses that we know infect human cells, or those that appear to pose the greatest risk of infecting us. But this is an ever-changing list. We need to expand the design of these vaccines to protect against all sarbecoviruses“, says the expert.

On how it works, the researchers highlight this Khosta-2 has spiked proteins that are used to enter human cells by binding to the angiotensin 2 (ACE2) protein found in the human body.

“Genetically, these strange Russian viruses resembled some of the others that had been found in other parts of the world, but because they didn’t look like SARS-CoV-2, no one thought they were really anything to get too excited about. “, Letko emphasizes, adding that “this changes a little bit our understanding of these viruses, where they come from and which regions are important.”

US health authorities are warning of a virus linked to muscle weakness

On the other hand, health authorities in the United States have released an alert about the spread of a common childhood virus that can cause muscle weakness or paralysis in rare cases. The Centers for Disease Control and Prevention (CDC) has called for priority attention to enterovirus D68, which often warns It causes a respiratory illness in children, with symptoms that are often mild but can become severe.

The agency explained that the family of enteroviruses is large and polio is in it, after pointing out that both EV-D68 and poliovirus can invade the nervous system and cause muscle weakness.

He also pointed out that sometimes V-D68 can lead to a condition known as acute flaccid myelitis, or AFM, which is characterized by inflammation in the region of the neck of the spinal cord.

As reported, some people who experience AFM have difficulty moving their arms, while others experience weakness in all four limbs.
