PHOENIX (3TV/CBS5) -- We all know the signs and symptoms of the flu.
“Fever, cough, sore throat, extreme tiredness," said Eugene Livar of the Arizona Department of Health Services.
And we all panic as soon as we think we may have the flu.
"I don't think you should panic when you have those symptoms. Just remember to go and see you care provider to get the help you need," said Livar.
Arizona has 173 reported cases of the flu since Sept. 30 and this week 40 reported cases.
"If we look at the five-year average, it's more if compared to last year. It's a little bit less as far as the number of reported cases” said Livar.
Influenza was the predominant strain last year in Arizona. As for this year, it's hard to tell and forecasting an outlook isn't easy.
"The most predictable thing about flu season is it's unpredictable. Many things factor into how severe the flu season will be, like how many vaccines did people get and what was the strain present in our community" said Livar.
But prevention is easy.
"You want to make sure you get the flu shot. And then it’s just a few simple steps, some things you do every day. Wash your hands, cover your cough and you want to stay from work or school so you don’t spread the illness," said Livar.
