I had the swine flu. Got tamiflu which worked and I feel better no more fever. Today is the fifth day since it started on sat am I still contagious?

I had the swine flu. Got tamiflu which worked and I feel better no more fever. Today is the fifth day since it started on sat  am I still contagious?

Probably not: The virus is transmitted via water droplets in your coughs/sneezes. If you are not coughing/sneezing etc...And that you took tamiflu already, it is not likely that you are contagious now. But, caution is always advised. Cover your coughs/sneezes and wash your hands... Good luck. ...Read more
