South-central Ontario has so far experienced a moderate flu season.

The Haldimand-Norfolk Health Unit registered three cases of influenza A this autumn.

Grip A is the most serious fear of the flu. Less viruses known as Influenza B are also in circulation during the flu season. However, the symptoms they produce are less attenuated than Influenza A.

The symptoms of influenza A include fatigue, fever, cough, problems with upper respiratory systems, such as nasal congestion, cured nose and throat pain, and occasionally nausea and vomiting.

Influenza A is potentially fatal in certain populations. This includes older, very young and people with compromised immune systems. Where the deadly disease is often a cause.

All three cases recorded at the local level were in Norfolk. None is registered in Haldimand.

The H1N1 virus has been identified as one of the synthetic flu A in circulation in Canada.

If the virus sounds familiar, this is because the H1N1 virus was responsible for the outbreak of the 2009 influenza epidemic. This epidemic is a concern for health authorities over the pandemic around the world.

Health officials are encouraged because the 2018 influenza vaccine protects against A-soda H1N1 flu.

Influenza vaccines have been ineffective in the past few years. Researchers have to guess which flu will be in circulation before deciding on the formula. When they think wrong, the vaccine offers little protection.

In e-mail, Dr. Shanker Nesathurai, Haldimand and Norfolk's Medical Officer of Health say it is too early to say whether the vaccine available this year was well suited.

In its latest report, the Public Health Agency of Canada says the influenza activity so far in December this year in southern Ontario was "sporadic". The incidence of influenza in eastern Ontario along the border with Quebec is more intense and described as "localized".

PHAC did not identify any areas in Canada where flu is considered widespread. There was no activity in the large northern Ontari section along the Manitoba border.
