    In the 1970s, there was an incident where these cells contaminated other cell cultures, so the researchers needed DNA samples from the Henrietta’s family to differentiate her cells from the others.

    I don’t understand. First, what was the point? I doubt there was a way to split the sample attacked by a cancer cells, they probably weren’t going to recalibrate the transporter and untuvix them.

    Second, weren’t there thousands of the copies of the sample? Why wouldn’t they compare it to one of them, instead of bothering the family?

    So first, i don’t think that article says they tracked them all.

    And second, if you can test them and rule out infection with certainty, why would they be ordered to isolate?

    I think the incubation period does play a role there.

    Authorities in St. Helena, the volcanic British territory in the South Atlantic where passengers disembarked, said they were monitoring a small number of people who were considered “higher risk contacts.” Those contacts were being told to isolate for 45 days, the St. Helena government said.
