Pentagon adopts 'social distancing' at coronavirus briefing

The U.S. military's official tally of servicemembers and related personnel who have been infected by the coronavirus likely undercounts the actual total, the Pentagon acknowledged on Tuesday, as a second servicemember in the United States tested positive for the virus.

"I think that it is likely, given what we are seeing around the world, and the fact that we have people all over the world, that there are more," Joint Staff Surgeon Air Force Brigadier General Paul Friedrichs told a Pentagon news briefing.

The U.S. Centers for Disease Control and Prevention (CDC) on Tuesday reported 696 cases of coronavirus, an increase of 224 from its previous count, and said the number of deaths had risen by six to 25.

The CDC said confirmed cases had been reported by 36 states and the District of Columbia, up from its previous report of 35.
