Fraser Health Authority has said that this year there's added urgency for British Columbians to get their annual flu shot.

The suggestion was prompted by a “recent spike in influenza activity”, according to a January 4 media release.

“In the last week, we have noticed a significant increase in influenza outbreaks across our region,” said Dr. Martin Lavoie, a medical-health officer for the regional health authority. “While seasonal increases in flu activity are expected, we remind people that if they have a non-emergency health concern they have many options in the community to help them avoid a trip to the emergency department to ensure emergency services are available for those who need them.”

The release states that since December 28, 2017, Fraser Health has recorded five confirmed cases of influenza plus another four cases it suspects are influenza.

The Fraser Health Authority covers most of the Lower Mainland outside of the cities of Vancouver and Richmond. Its area includes Burnaby, Coquitlam, and Surrey, among other jurisdictions.

Symptoms people are advised to watch for include fever, headache, fatigue, muscle aches, and cough. The release emphasizes that senior citizens are especially susceptible to influenza and should exercise special caution.

“Complications from influenza, such as pneumonia, are more common in the elderly and those with heart, lung or other health conditions,” the release continues.

Fraser Health’s recommendation for an annual flu shot is however not limited to seniors. It’s for everyone over the age of six months. The release notes that the shots are available for free for citizens aged between six months and five years and for those over the age of 65.
