Omicron 2, better variant? “Deadly like others in the unvaccinated”

Omicron 2 more contagious, but better? Not for all. Omicron BA.2 “, a sub-variant of Sars-CoV-2 now dominant in the world,” is as deadly as the previous variants when infections occur in unvaccinated elderly. ” Scripps Research Translational Institute, Professor of Molecular Medicine, based on a study conducted in Hong Kong and published on the pre-print platform ‘MedRxiv’. To analyze the effects of Omicron 2, Hong Kong is a special observatory. A sort of laboratory at open sky, considering that the autonomous territory of Southeast China recorded “in the first 2 years of the pandemic” just “12,631 confirmed cases of Covid-19 with 213 deaths”, recall the authors of the work, a team from the University of Hong Kong . The real ‘tsunami’ the island did not experience like most of the planet in early 2020, but in early 2022, when “a major wave sustained mainly by Omicron B A.2.2 – the researchers report – caused over 1.1 million Sars-CoV-2 infections with more than 7,900 deaths “. On Facebook Topol therefore highlights how precious “the experience of Hong Kong with BA.2” is, concerning precisely “a population with a previous low exposure” to the virus. Well, “our data – explain the scientists – indicated” for Omicron 2, compared to other variants of the pandemic coronavirus, “shorter” values ​​for 3 parameters: “The incubation period; the serial interval”, ie the time that passes between the symptoms of an infected person and those of a person who infected infects, and “the time of generation of infections”, that is, the period that elapses between the contagion of a primary infector and that of the cases that derive from it. “However, patients infected with Omicron BA.2.2 without having undergone a full primary course of Covid vaccination”, the authors add, “appeared to have a similar mortality risk to those infected in previous waves with the ancestral strain.” of Sars-CoV-2.
