DHS Secretary Alejandro Mayorkas tests positive for Covid

Neither Biden nor any principal officials have been found to be a close contact of Mayorkas, the White House said Tuesday. The most recent contact took place at an outdoor event outside of the 48-hour exposure window.

Breakthrough infections for fully vaccinated people are rare, and those cases have much lower rates of serious illness, hospitalization and death from Covid. People who are unvaccinated are 11.3 more times as likely to die from the disease than those who are vaccinated, according to CDC data from August.

Mayorkas was supposed to travel to Colombia with Secretary of State Anthony Blinken, but will now be working from home, according to CNN.
