If you have that sniffling, sneezing, aching, fever and all over yucky feeling—chances are you have the flu. So you run for the over-the-counter flu meds, right? But hold up just a second. Researchers say that over-the-counter flu medicines may contribute to the spread of the virus. Well, that's comforting. These meds typically includes ibuprofen, acetaminophen and acetylsalicylic acid to relieve fever and aches. But the fever actually lowers the amount of virus in the infected person to reduce the chance of transmission to others. Researchers found that treating a fever increases the number of annual cases by 5%. To put it in more specific terms…that’s equivalent to 1,000 additional deaths a year in North America.
