If the virus is caught in the first stages it can be treated with antiviral medication prescribed by the doctor, but if given a longer time frame, the only option then is to treat the symptoms.
"Unless you get into the doctor the first two days you're really only treating the symptoms" Cullen said. "People will take Tylenol or Ibuprofen to get rid of a fever or an antihistamine to dry up a runny nose but those are just mainly comfort measures."
While those measures of comfort are important to a person's well-being, the important part to remember is to prevent the spread of the flu, an issue that is difficult to contain in a world that's constantly moving.
"I really believe that it starts in one area and spreads just because our society is so mobile," Cullen said. "So I think it's important that we (keep) pushing to get that vaccination out to the public."
