New York : According to a study, infection with the Omicron variant of Kovid-19 is as dangerous as the delta, alpha and other variants, which have killed thousands of people worldwide.
Scientists in South Africa discovered Omicron in November last year. Multiple investigations conducted in the UK, South Africa, Canada and elsewhere have previously shown that it is more transmissible than other SARS-CoV-2 variants, but less severe. It was also said that this resulted in fewer hospitalizations and deaths. Unlike Delta, the highly contagious form affects the upper airways more than the lungs, causing symptoms similar to the common cold. The World Health Organization (WHO) has warned that it should not be taken lightly on several occasions.
However, an investigation by Massachusetts General Hospital and Harvard Medical School found that the risks of hospitalization and mortality were "essentially comparable" between the first round of COVID-19. The researchers claimed in the pre-print report that "our analysis implies that the intrinsic severity of the omicron variation may be as severe as the earlier variants." Despite indications that Omicron had the potential to evade the vaccine, the new study found that vaccination helped protect people from the severe effects of the virus.
Researchers matched state-level vaccination data to quality-controlled electronic health records from a large healthcare system in Massachusetts, which included 13 hospitals. They then conducted a weighted case-control study of over 130,000 COVID patients to examine the risks of hospital admission and mortality in the SARS-CoV-2 waves.
Previous waves showed higher unreasonable rates of hospital admissions and mortality than the Omicron period.
