Silicon Valley bans gatherings of 1,000 plus
SAN FRANCISCO — With Silicon Valley reporting a rapidly rising number of confirmed coronavirus cases, the health officer for Santa Clara County issued a rare legal order banning mass gatherings of 1,000 or more people.
Santa Clara County, with 43 confirmed coronavirus cases and one death, has California’s largest number of confirmed infections. After declining an earlier recommendation to halt mass gatherings late last week, the San Jose Sharks said the team would abide by the county’s new order at SAP Center in downtown San Jose, which is enforceable by the county sheriff and city police agencies.
“We are clearly facing a historic public health challenge,” the Santa Clara County health officer, Dr. Sara Cody, said at a news conference Monday night. “The number and type of cases to date indicate that the risk of exposure to this virus in our community is increasing.”
There has been a rapid increase in the number of confirmed cases in Santa Clara County, rising from 11 cases on Thursday to 43 on Monday. Of the total, 21 in Silicon Valley are believed to have been infected by someone unknown in the community, and not by getting infected by traveling to an area where the virus is circulating, nor by having been infected by someone with a confirmed case.
“Because our emerging data tells that we have more extensive community spread than was apparent to us even five days ago, we must take more actions to slow the spread of disease and to protect the public,” Cody said.
Cody acted Monday night just hours after she announced the first death in Santa Clara County, that of a woman in her 60s with underlying medical conditions. The patient was the first in Santa Clara County to be identified as being infected by the virus through an unknown source, meaning it was the first sign that the virus had begun spreading in the community.
It’s not clear why Santa Clara County is seeing a particularly fast rise in cases over other counties. Coronavirus cases could be on the sharp rise elsewhere, but a lack of testing capability is thwarting officials’ ability to track the spread of disease. More testing recently became available in Santa Clara County, and, “as we’ve tested more people, we’ve found more cases. And we anticipate many more cases as commercial laboratories come online to test for this illness,” Cody said.
Older adults and those with underlying health conditions, such as diabetes, obesity, asthma, disease of the heart, lung or kidney, and those with weakened immune systems, are at much greater risk for severe illness and death. The virus can cause severe illness by moving from the throat, nose and sinuses into the lungs and airways, where it hijacks those cells, destroying them and spreading more copies of the virus throughout the body.
About 19% of those infected with the virus can suffer severe or critical symptoms, according to an analysis of nearly 45,000 patients in China. About 5% show critical symptoms, and half result in death.
