JAMA: Omicron causes more excess deaths in Massachusetts than Del.

New research from the medical journal JAMA shows that the novel coronavirus variant Omicron has caused more additional deaths than delta virus in Massachuset.

And it took less time: Omicron lasted 8 weeks, Delta lasted 23 wee.

 Excess deaths, the difference between the actual number of deaths and the expected number of deaths for a population in a region, is a more comprehensive measure of the number of deaths directly or indirectly caused by the vir.

The study showed that the increase in all-cause excess mortality in Massachusetts during the Omicron infection epidemic reflected higher fatality rat.

Specifically, during the 23-week Delta wave, the excess deaths in Massachusetts were 1,975 (27,265 observed deaths, 25,290 expected deaths, 95% confidence interval: 671-329

There were 2,294 additional deaths (12,231 observed deaths, 9,937 expected deaths, 95% confidence interval: 1,795-2,763 additional deaths) during the 8-week infection wave of Covid-19 Omicr.

The weekly excess mortality rate for Covid-19 Omicron and Delta was 34 times (95% confidence interval: 14-5

background

With a population of 9 million, Massachusetts is one of the wealthiest and most technologically advanced regions in the United Stat.

It is home to top universities such as Harvard and MIT and is home to many pharmaceutical gian.

80% of the population has been fully vaccinated, compared with about 60% in the United Stat.

"With very high vaccination rates, omicrons are still causing very high numbers of deaths," Krumholz sa.

Research has shown that omicron is responsible for excess deaths in all age groups 18 and over, with the highest number of excess deaths in the age group 65 and ov.

Bill Hanage, an epidemiologist at the Harvard School of Public Health who was not involved in the study, thinks the higher excess deaths in Massachusetts may be related to the state's efforts to curb the spread of the virus during the Delta varia.

Hanage published a paper in the New England Journal of Medicine (NEJM), an international authoritative medical journal, in February this year, pointing out that the milder symptoms of omicron virus infection may be due to the existence of more immunity in the infected person rather than the The virus itself is "mil.
