U.S. CDC director to self-quarantine after exposure to person with COVID-19 

Dr. Robert Redfield, the head of the U.S. Centers for Disease Control and Prevention, will self-quarantine for 14 days after he was exposed to a person at the White House who tested positive for COVID-19, CNN reported citing a spokesperson from the agency. 

"CDC Director Dr. Robert Redfield has been determined to have had a low risk exposure on May 6 to a person at the White House who has COVID-19. He is feeling fine, and has no symptoms. He will be teleworking for the next two weeks," the spokesperson told CNN.

It's not immediately clear who Dr. Redfield came into contact with at the White House. 

But Katie Miller, the press secretary to U.S. Vice President Mike Pence, was the latest person inside the White House to test positive for the virus, on Friday.

The number of infections in the U.S. has surpassed 1.3 million, reaching 1,300,079 as of 3:32 p.m. (1932 GMT) on Saturday, according to Johns Hopkins University.

U.S. cases account for nearly one-third of the global total.

Meanwhile, the death toll in the country hit 78,320, with New York remaining the hardest-hit state with 333,122 cases and 26,563 deaths, followed by New Jersey where 137,397 cases and 9,116 deaths were recorded so far.
