The (US) CDC has just issued a major change in risk factors for COVID-19 infection

The American CDC has just significantly expanded the definition of “a close contact” for someone with Covid-19.

Up till this week, that definition was someone who had spent 15 consecutive minutes or more within six feet of an infected person.

But now because of a single case of a prison guard in Vermont who became infected after he spent a cumulative total of more than 15 minutes (that is, it was a total of more than 15 minutes although each exposure was for a shorter time period than that), the CDC now says that if you spend 15 or more cumulative minutes – not necessarily consecutive – in the presence of infected individuals, you should be considered a close contact.

Just one more thing to worry about, I guess.
