White House rushes to assess spread of virus in top US ranks in week of presidential debate
A scramble is under way in Washington to determine how far coronavirus infection has spread in the top ranks of US leadership after Donald Trump tested positive, in a week that included a presidential debate, political rallies and White House meetings with Congress.
The White House said its medical unit had begun contact tracing on Thursday. Among those who may have been exposed is the Democratic challenger for the presidency, Joe Biden, who stood a few metres away from Trump for the 90 minutes of Tuesday night’s televised debate. Epidemiologists said that if Trump tested positive on Thursday morning he could have been infectious at that time.
