The Flu (Influenza) is a highly contagious infection of the nose, throat and lungs caused by the influenza virus. It can be a serious illness for some people.
Niagara Region monitors the spread of flu and flu-like illnesses on an on-going basis. During the months of September to April, influenza outbreak activity will be reported.
Most people infected with influenza do not get laboratory testing and so actual infection numbers are likely much higher. Your health care professional may or may not test you for influenza based on your level of risk. Only laboratory confirmed cases are reported to Public Health.
