Yesterday i visited one friend's home for some personal reason. From a week some of them are sick. He said there is viral infection. He is also sick from last 7-8 days. I was there for 5-10 minutes. I was in mask and goggle. I touch there surfaces but sanitize hands after some time. I am exactly sure are they suffering from viral or covid. If it is a covid then what are the chances of infection to me. I was also covid positive in march 21 and recover with zero Hrct score. Also, i had taken one covid vaccine one month before. Pls. Help.
