Just found out a quarantined person in my area had many visitors. The person seem to think it was ok because he never left the house. He also had a child staying with him that was going to school.
There is no way to enforce quarantine for every single person who is ill. We don't have the resources for that. In fact they are already telling people who get sick to NOT go to the hospital or doctor unless it's an emergency in order to preserve the resources. 80% of those infected get only mild symptoms. Less than 10% need medical help. Not everyone needs to go to the hospital. Not to mention it may not even be coronavirus. The flu is still going around. The common cold is still going around. If everyone who gets a sore throat goes to the hospital and demands a test, we will have a BIG problem. Not just with overwhelmed hospitals, but you may be introducing a new virus to the mix.
