Today’s news about coronavirus: An estimate says nearly half of Connecticut residents have been infected with COVID-19

The latest news on coronavirus from Canada and the rest of the world Sunday. This file will be updated during the day. Web links to longer stories, if available.

8:46: Northern Health declared the COVID-19 outbreak at Wrinch Memorial Hospital on October 29th.

The outbreak was declared on September 27, and then eight patients and two staff tested positive for the virus. One patient death was recorded, Northern Health said.

Northern Health actively monitors and follows up all laboratory-confirmed cases of COVID-19 among staff and patients at all their facilities.

8:45: Russia has registered a new daily high number of coronavirus cases as many of the country’s stores remain closed in an attempt to counter a week-long increase in infections.

The National Coronavirus Task Force on Sunday reported 40,993 new infections compared to the previous day, an increase of more than 700 compared to the previous record a day earlier. Russia has recorded records of infections or deaths almost daily during October.

The death toll reported Sunday was 1,158, just slightly lower than Friday’s record of 1,163.

That brought Russia’s official COVID-19 death toll to 238,538, by far the largest in Europe. More than 8.51 million infections have been registered in the country with 146 million during the pandemic.

Sunday at 8.44: While vaccination remains the most important tool to end Connecticut’s COVID-19 outbreak once and for all, experts say another factor may also play a role: immunity from previous coronavirus infection, known as natural immunity.

Natural immunity is not absolute and is not indeterminate. As with vaccination immunity, it fades over time. But research suggests that those who have had COVID-19 are unlikely to catch it again right away and therefore are unlikely to contribute to a broader outbreak in the near future.

Although estimates vary on the proportion of Connecticut residents who have been infected with COVID-19 since the onset of the pandemic, a model suggests that the number may approach 50%. If that is the case, experts say, natural immunity among people who have been infected in the past can make a difference in ending the pandemic in the state.

How much difference, however, is still up for debate.
