It's just the start of the flu season, but the virus has already spread widely across MA, according to state epidemiologists who track and report the flu to the Centers for Disease Control.

Taiwan has about 2.5 million to 3 million people with chronic liver disease and those who have liver fibrosis or liver cirrhosis have weaker immune systems and are at greater risk of developing pneumonia after catching the flu, which can lead to serious complications or even death, said Lee Mau-hwa (李懋華), chief executive officer of the Good Liver Foundation's medical development department.

Goudreau says "the relatively low percentage of effectiveness in Australia is due to many factors, including the shifting and changing of the flu virus each season".

"There seems to be an uptick, especially in the last week, in flu-like illnesses", he said.

The CDC confirmed flu cases in 2017 are at more than 7,000 right now, which is more than double what they were at this time past year.

People taking medication for hepatitis C or undergoing interferon therapy should not worry that the flu vaccine will affect their treatment, Lee said, adding that they should get vaccinated as soon as possible for protection against the flu.

The CDC recommends everyone six months and older get a flu shot each season.
