It's a mystery. My son in law was very very sick for two weeks. She had him quarantined in the house as best she could. But she still brought him soup and fresh clothes, medicine, etc. She never got sick either. She tested herself twice during those two weeks. So either y'all got lucky or there's some other mystery like blood type, immunity, genetics, something we don't know.
Cloaked in disinformation, politics, and maybe evil.
