While antiviral treatment is recommended within two days after the start of flu symptoms in people who aren’t at high risk for complications, the guidelines note they should be prescribed to those at high risk even if they have been sick for more than two days.
Latasha Haynes was 34 when she almost died of the flu last year. What started as a little coughing and fatigue ended with two blood transfusions and a diagnosis of congestive heart failure weeks later. Flu had caused damage to her heart muscles and the saclike tissue around it. She survived, but just barely, and it took her months to recover.
