Question: how long are you contagious with swine flu after taking tamiflu?
Answer: It showed that 80% were still shedding virus after five days of illness, 40% at seven days, and 10% at 10 days. People who were treated with Tamiflu shed virus for an average of three fewer days than those not given the anti-flu drug, “but still, some were showing signs of viral shedding after a week,” Lye tells WebMD.
