Most with coronavirus not sure how they caught it, by Robin Foster.

A majority of Americans who are diagnosed with COVID-19 don’t know who passed the virus to them, two new government reports show.

In the first study, researchers found that only 27% of more than 360 Colorado residents diagnosed with COVID-19 knew of any contact with someone who had coronavirus in the two weeks before they were tested. …

“This just emphasizes the fact that while we know how COVID-19 is transmitted we do not have a good idea of how to assess our risk when interacting with other people,” said Dr. Eric Cioe Pena, Director of Global Health at Northwell Health, New Hyde Park, NY. …

Among those in the study who knew they had come into contact with an infected person, the most commonly reported relationship was a family member (27%) or a coworker (25%) in the Colorado study. In the second study, it was most often a family member (45%) or a work colleague (34%).

In the Colorado study, the most commonly reported activities in the two weeks before becoming ill included attending gatherings of more than 10 persons (44%), traveling domestically (29%), working in a health care setting (28%), visiting a health care setting not as a health care worker (23%), and using public transportation (22%).
