Quarantine the household all together.

Hope this Helps

Answer 2

The correct answer should be 3.Quarantine the household all together.

They couldn't quarantine only one person because they didn't know whether their family also got it and they also believed that the diseases could be transferred from the possessions of the people who had it. This is why they would quarantine an entire house and if they died they would often burn the entire house down.
