California Gov. Gavin Newsom is in quarantine, again, after a staffer who came in close contact with him tested positive for COVID-19.
Newsom was tested for the virus after the news and the results came back negative, according to a statement from his press office.
The individual who tested positive, and who has not been named, was also in contact with various other staff members. They too were tested and their results came back negative.
"In an abundance of caution, the Governor will begin a ten day quarantine per state guidelines. The Governor and staff will be tested again in the next few days and continue to follow state and CDC guidelines," the press office said in a written statement. "We wish our staff member who tested positive well."
The office said its staffers have been following guidance from the California State law and the California Department of Public Health. Among other things, staffers have been wearing masks.
"Early on in the pandemic, the Governor's Office put in place a number of protocols that minimized the amount of staff physically present at work, converted most in person meetings to video conference calls, instituted a no questions asked remote work policy and reduced seating capacity in meeting rooms for in-person meetings that can't be done remotely. Those policies are still in effect and will be for the duration of the pandemic," they said.
Newsom also went into quarantine one month ago, when he and his family learned they had come into contact with a California Highway Patrol officer who had tested positive for COVID-19. The officer provides security for the Newsom family.
South Africa is seeing COVID-19 cases rise as the new strain of the virus spreads though the country.
According to health officials, the new variant, known as 501.V2, is responsible for new cases, hospitalizations and deaths.
"It is still very early but at this stage, the preliminary data suggests the virus that is now dominating in the second wave is spreading faster than the first wave," Professor Salim Abdool Karim, chairman of the government's Ministerial Advisory Committee, said in a briefing to journalists, according to the Associated Press.
South Africa has had 921,922 confirmed cases and 24,691 deaths, according to Johns Hopkins data. In the past day, it has seen 9,445 new cases and 152 new deaths.
Experts are saying the new strain of COVID-19 may be more infectious than the original virus.
