Santa Clara County announced 55 new confirmed cases of coronavirus Sunday, meaning that the county’s number of people known to have the virus has more than doubled in a week’s time.

The newest total now stands at 646, compared to the 302 cases reported as of March 22, according to data released by the county Public Health Department.

There was one respite in the new figures: No new deaths were recorded in the 24-hour period that ended Saturday evening. The county’s total of COVID-19 fatalities remains at 25.

It’s unclear how many total cases there are in the county, which has been under a shelter-in-place order for nearly two weeks as part of a wide-ranging effort to slow the spread of the virus. The first confirmed case in the county, which has nearly 2 million residents, was on Jan. 31.

Gov. Gavin Newsom announced during a visit to Sunnyvale on Saturday that the number of people in intensive care beds across the state because of the virus doubled overnight to 410 from 200 on Friday.

Officials said they hoped the weekend’s rainy weather would prompt more people to remain indoors and stick to the shelter-in-place order, with social distancing being the best tool to fight COVID-19. State parks and Bay Area park systems have either closed or curtailed access to prevent crowds from gathering, and those measures could be tested soon with dry, warmer weather forecast for the next few days.
