Severe acute respiratory syndrome coronavirus 2

Vacationers huddling on ships and aircraft for a visit to some Greek summer paradise will be exposed without any shield to the new subvariants of the virus.

Since the new sub-variants are evading vaccines and new vaccines are still delayed, it seems that the only protective measures against the coronavirus are masks, distances and hygiene rules.

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 coronavirus pandemic is not totally over, but risks of infections and deaths have reduced, a prominent Turkish physician said on April 12.

"The pandemic is not over yet. But we are at the end of the tunnel," said Tevfik Özlü, a professor from the Health Ministry's Coronavirus Science Board.

Preclinical data on the SARS-CoV-2 vaccine developed at MedUni Vienna show that it is effective against all known variants of SARS-CoV-2, including Omicron - even in individuals who have not yet developed immunity to SARS-CoV-2 as result of vaccination (unresponsive cases). The survey data was recently published in the leading journal Allergy.

An early version of COVID-19, which seems to have been created in the laboratory, was discovered in samples from a Chinese biotechnology company, writes Sara Knapton, the Science Editor for The Daily Telegraph.
This finding justifies claims that the virus may have originated as a laboratory experiment that accidentally leaked.

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.

The new sub-variant of Omicron BA.2 is already in Bulgaria. This is shown by data published on the website of the National Center for Infectious and Parasitic Diseases (NCIPD).

A sub-variant of the Omicron coronavirus variant has been found in 57 countries.

This was announced by the World Health Organization (WHO), reports AFP and BTA.

It is possible that it will be even more contagious than the original version, according to AFP.

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.

234 clinical samples of coronavirus were analyzed by sequencing at the National Center for Infectious and Parasitic Diseases. Clinical samples were taken from patients with COVID-19 in the period 03-13.01.2022.
