It seems that the emergence of viruses is almost never ending, after warning virologists of the discovery of a virus similar to Corona found in bats in the depths of Russian caves.
According to the British newspaper, DAILYMAIL, the virus is called “Khosta 2”, and it can infect humans, as it is resistant to vaccines, and it is from the same family as the coronavirus.
After the emergence of this virus, here are 4 epidemics that threaten the world in the current period.
– Khosta 2
Experts affiliated with the Russian government have recognized the Khosta-2 virus, as it is classified as a branch of the coronavirus family tree, and American virologists who have conducted experiments with the Khosta-2 virus – fear it is “resistant” to vaccines circulating during the pandemic, have found that it is able to It sticks to human cells easily in the same way as corona.
University of Washington researchers in the United States also conducted tests on the virus, hoping to learn more, as Dr. Stephanie Seifert and his colleagues examined the Khosta-1 virus, and tests showed that it was able to infect human cells in a near-identical way as Corona, using a spike-like protein on its surface, attached The virus contains an entry enzyme found on the outside of human cells, called ACE-2.
The experiments also tested whether Corona vaccines or drugs could destroy it, if it could be transmitted to humans (a process known as zoonosis), and researchers confirmed that the virus was “completely resistant” to one of the antibody drugs made by Eli Lilly. Laboratory work also showed that Khosta-2 also appeared to be “resistant” to two doses of Moderna and Pfizer vaccines.
For his part, Dr. Seifert and his colleagues said that it is still possible for natural immunity to the Corona virus, or perhaps even that acquired through vaccines, to overcome the virus, adding that their findings prove that they “pose a threat to global health” and “highlight the The urgent need” to develop global vaccines for the Corona virus.
Corona and its variants
The new Corona virus “Covid-19” continues to reveal its many mutations that are almost endless, causing the virus to spread in several places around the world.
According to sciencealert, a new mutant of corona has been discovered, which is “BA.4.6”, one of the main mutant of “Omicron”.
And the latest report on Corona mutant, issued by the Health Security Agency in the United Kingdom, revealed that during the week that began on August 14, the new mutant “BA.4.6”, accounted for about 3.3 percent of infections in the United Kingdom, so that the percentage began to increase to currently constitute about about 3.3 percent. 9 percent of recorded cases.
As confirmed by the US Centers for Disease Control and Prevention, “BA.4.6” now represents more than 9 percent of recent cases recorded across the United States, and the mutated has also been monitored in many other countries around the world.
Symptoms of the new mutation
The symptoms of the new mutation are similar to those with the Omicron mutation, in the upper respiratory tract and rarely in the lower respiratory tract.
runny
muscle pain
cough
fever
Runny nose
sneezing
Headache.
– monkeypox
Monkeypox is still a threat to humans around the world, as well as in Egypt, after the Ministry of Health and Population announced, yesterday, Tuesday, the discovery of a new case of a patient infected with the virus.
The ministry said in an official statement, that through the ministry’s efforts and plan to secure, follow up and monitor the epidemiological situation at the country’s entry points to monitor suspected cases of any epidemic diseases, a patient from one of the Arab countries tested positive for the monkeypox virus coming from abroad on September 25.
Monkeypox is caused by monkeypox virus, a double-stranded enveloped DNA virus of the Orthopoxvirus genus of the family Poxviridae.
Symptoms
Skin rashes and the development of lymph nodes (enlarged lymph nodes) in several areas of the body are the main symptoms that distinguish this viral infection from others.
Fever, headache, muscle aches, chills, backache and fatigue
A few patients may also develop coughing, nausea, and shortness of breath.
– influenza
One of Britain’s top health experts has warned of a “lethal strain” of the influenza virus that is currently spreading around the world, noting that it may pose a greater threat to public health than Corona this winter.
“Covid 19 will continue to pose a significant challenge to the authorities, but the low levels of residual immunity to influenza in the general population are worrying,” said Susan Hopkins, chief medical adviser to the UK’s Health Security Agency, stressing the specific danger of the H3N2 strain.
The expert expected that “influenza and other respiratory diseases will rebound this winter, after they were largely addressed through closures and social distancing during the Corona epidemic,” according to the British “SKY News”.
And she continued: “The H3N2 influenza strain can cause particularly severe illness, if you are elderly or weak for any other reason you are at greater risk, so getting a flu vaccine makes sense and potentially saves your life.”
