To avoid spreading the virus, patients should avoid other people if possible.
“It may seem rude at first, but people tend to understand and appreciate it when you explain you don't want to share your illness,” he said.
People are most likely to infect others with the flu starting about a day before their symptoms begin and through the first five to seven days of the illness. Once you start to feel better, you're not likely to pass it on to anybody else, Prescott said.
If all goes well, most people are clear of the flu after a week or so. But if it sticks around longer, return to the doctor, Prescott said.
A virus that hangs around can give birth to a secondary infection or even pneumonia.
“There is no silver bullet to absolutely ensure you won't get the flu,” he said. “But if you take reasonable precautions, your chances of avoiding a week of body aches, sneezing and nausea will improve significantly.”
