Israeli study: The British surrogate sees serious COVID-19 cases swell

A study by Clalit Health Services, Israel’s largest health maintenance organization (HMO), found that the UK’s Covid-19 variant is causing an increase in more severe cases than the original virus. Clalit Clalit Health Services screened 50,000 unvaccinated people who tested positive for Covid-19 during January and February, when the British variant was the dominant virus strain in Israel. Researchers compared them to 60,000 unvaccinated people in Israel who had been diagnosed with Covid-19 in previous waves, before the identified mutation first appeared in Britain. According to the data, before the Covid-19 variant in the UK, there was a 1% chance for people between the ages of 30 and 50 to become seriously ill, 3.7% for those between the ages of 50 and 60 and 14.5% for those over the age. 60 years old. But in January and February in Israel when the British alternative was prevalent, there was a 1.3% chance that people aged 30-50 would become seriously ill, 5.5% for those aged 50-60 and 19% for those over 60. . “During the month of January and February at the third lockdown and at the height of the vaccination launch in Israel, we saw an inexplicable phenomenon,” Clalit said. “Expectations predicted an immediate and significant decrease in the number of new Covid patients suffering from serious illnesses every day. Practically speaking, though.” From the high rate of people over 60 who received the first vaccine dose, and then until the second dose, the decrease in the number of seriously ill patients in general was moderate. ” It was during this period that the alternative first identified in Britain became dominant in Israel. This strain was first seen in Israel at the end of December and by the beginning of February it had already, according to estimates by the Ministry of Health, the most infections in Israel. From several initial reports in England, it appears that this variable may cause significantly more serious illnesses and more deaths, although there is no data from Israel regarding this potential phenomenon. ”Director of the Clalit Research Institute, Professor Rann Baleser, said,“ Our data provide an explanation. Possibly why in the first weeks of 2021, we did not witness a sharp drop as expected in the number of new serious daily cases, despite the extent of the vaccination campaign and the tremendous efficacy of vaccinations as seen in Clalit’s primary research published this morning in the New England Journal of Medicine. He added: “According to our findings, some general decline in those suffering from serious diseases of all ages, after vaccinations, was seen later and in a more limited fashion than expected, due to the sharp and simultaneous rise in serious infections, among the unvaccinated people in All age groups affected – an increase of 70% compared to last year. With the period one month before.

Significantly among the unvaccinated population, hence it can be assessed that the British variant is not only more contagious, but also more dangerous.These results coincide with reports from Britain of the increased aggressiveness of the new strain.Published by Globes, Israel business news – en.globes .co.il – on February 26, 2021 © Copyright Globes Publisher Itonut (1983) Ltd. 2021
