The US Centers for Disease Control and Prevention has updated its definition of a close contact with a Covid-19 patient to include multiple, brief exposures, after a Vermont prison worker appears to have been infected that way. The agency changed the definition after a report from Vermont of a corrections officer who became infected after several brief interactions with coronavirus-positive inmates -- none of them lasting 15 minutes.
