Covid-19 crisis Testing family members of infected persons
We now test the family members of infected person to find out who has been infected with the virus. 

What about the other family members who did not get the virus?

Could they have been infected also, and the virus has been blocked by vaccine or natural immunity?

This is an important data. 

It can be detected by carrying out a antibody test. An infected person who has recovered will have the antibody.

I hope that the task force will carry out an antibody test of the close contacts who are tested negative for the virus.
