Last week, I found out that dogs can get the flu. Now I'm learning that hives can be an indicator that you have the flu, even if you have no other symptoms!
A 6-year-old Tampa Bay boy tested positive for influenza after contracting hives, even though he was otherwise asymptomatic. Brodi Willard said her son came home from school with what she initially thought was a rash from an allergic reaction, and every time he would scratch, more would appear. She took him to the doctor, and a flu test came back positive.
