Sarbecovirus

For the third year Greeks will celebrate Easter with care and personal protection measures, but closer to normal than the previous two years. SARS-CoV-2 is persistent and through its variants reminds us that it is still with us.

The advent and rapid prevalence of the Omicron strain demonstrates the potential of SARS-CoV-2 to evolve its ability to transmit and cause disease. What is particularly surprising, however, is that the origin of the Omicron strain does not appear to have originated from any of the dominant SARS-CoV-2 variants such as the Alpha, Beta, Gamma or Delta strains.

Co-infection between influenza strain A (H3N2) and SARS-CoV-2 proved by National Center for Infectious and Parasitic Diseases (NCIPD)

129 cases of the viral variant Omicron of SARS-CoV-2 have been identified in Bulgaria after cell genomic sequencing performed by the National Center for Infectious and Parasitic Diseases.

227 cases of the viral variant Omicron of SARS-CoV-2 have been identified in Bulgaria after cell genomic sequencing performed by the National Center for Infectious and Parasitic Diseases.

12.036 people lost the fight against the coronavirus, 41 of them in the previous day.
3.304 people were hospitalized, and 194 were on respirators.
A total of 1.268.787 cases of coronavirus have been confirmed in Serbia so far.
Let us remind you, 1.884 infected people were registered on Tuesday, and 40 people died.

Chewing gum, which reduces the risk of human-to-human transmission of the coronavirus, was developed by researchers at the University of Pennsylvania.

The researchers performed experiments on the saliva of people infected with the SARS-Cov-2 coronavirus, adding ACE2 protein contained in chewing gum to test specimens grown in the laboratory.

What do we know about the new SARS-CoV-2 Omicron variant identified by the WHO as "alarming"? The answers are given by the President of the Bulgarian Society of Medical Virology and a member of the Expert Council of Virology under the Minister of Health - Prof. Dr. Radka Argirova, MD.

Why does the coronavirus mutate?

South African scientists have identified a new variant of the virus that causes COVID-19, and the World Health Organization gave it the spy fantastic name "omicron" within days, due to a series of mutations in its protein spikes, nanomechanical tentacles that connect and break into cells, scientific alarms have begun to sound off, writes Wired.

According to the World Health Organization, a new variant of the coronavirus called Omicron is a cause for serious concern because it has a large number of mutations. Early tests suggest an increased risk of re-infection, according to the WHO.

British virologists have reported the emergence of a new strain of coronavirus containing a number of mutations that potentially make it more resistant to vaccines than any other genetic variant of SARS-CoV-2.
