Hi guys so I rly need help. My brother moved out months ago to protect us from covid. On the 21st of January my parents helped him buy a car. So obvi he didn’t have anything then. Sometime after, he got sick and thinks he caught it already.

He never took a test after bc he was sick for a day. A week later his roomate tests positive and she leaves the apartment and goes to quarantine in one of those hotels that you go to if u have covid.

He took a test around the same time as her but his came back negative. Hers positive. I’m assuming he had it before her and spread it to her bc they live together.

And today he dropped off clothes for my mom to wash and do laundry. They stayed outside with masks and she washed it. Is it possible that he could have spread it to my mom given the circumstances?

Plz let me know I’m super scared
