If people can spread the virus without showing any symptoms, how can I tell who’s infected and who’s not?
You can’t, said Dr. James Phillips, chief of disaster and operational medicine at George Washington University Hospital.
“We’re so far behind on testing, there’s only one way we can be certain not to transmit the virus and be certain not to get it ourselves,” Phillips said.
“We need to start treating every person as though they have this. And everyone needs to treat us like we have it, and socially distance ourselves in that manner. Because until we have testing, we don’t know who has this. And we’re not sure when they start spreading it.”
That’s why it’s so critical to avoid crowds, stay at least 6 feet away from others, wash or disinfect your hands, and stop touching your face.
