Friend works in a local factory (not 1 that has been on the news) 1 member has tested positive, the company traced who this person has been in contact with and 30 people were sent home for tests. The 1s that have came back negative are back in work after 3 days off, others are still waiting for results. Am I wrong in thinking they still should isolate for at least 7 days. They could have only just come in contact so would still show up negative. So confusing.
