The end date for flu season can be unpredictable, however, the South Dakota Department of Health provides a weekly update of local cases here. The Fort falls in the Edmonton Zone along with other communities like Beaumont, St. Albert, Stony Plain and Spruce Grove.
Goldman said a flu is contagious about 24 hours before symptoms appear and 72 hours after the fever is gone. The total number in Alberta is 63, so far.
The number of flu cases in Saskatchewan has jumped almost 650 since January 27.
The numbers are among figures that show a big rise in new cases province-wide the last month.
"When those people become sick, that's when they are hospitalized, because they get more severely ill", he added.
The flu season typically lasts into March.
The CDC does say one shot is enough for most adults.
The flu shot's overall effectiveness against all strains was pegged at 36 percent, the CDC said. He said measuring can be tricky as there's a number of factors to consider. For that group of people, Goldman said Tamiflu is the recommended treatment. "It could be an issue of convenience, it could be due to more awareness of it".
If you have flu symptoms, contact your doctor to see if an antiviral medication would be a good choice for you.
"Flu in general is pretty unpredictable, so we can't really predict why one strain might predominate one season over another", Tan said. It can cause mild to severe illness, and at times can lead to death.
Dr. John Goldman, an infectious disease specialist at UPMC Pinnacle, said that even though the flu season is hitting residents harder this year, the emergency room is not always going to be the answer. While it's not impossible to catch the flu in the spring and summer months, the warm weather that draws people outside is a killer for the bug. It changes and mutates just enough to get it out of the range of protecting of the vaccine.
