Global Influenza Surveillance Subsides

The World Health Organization (WHO) recently published Influenza Update N° 440, influenza activity continued to decrease following a peak in late 2022.

As of March 6, 2023, influenza A viruses predominated, and the proportion of influenza B virus detections increased during the current reporting period.

In the countries of North America, most indicators of influenza activity decreased to levels similar to or below levels typically observed towards the end of the season.

In Europe, overall influenza detections remained stable, and influenza positivity from sentinel sites increased in the most recent week, remaining above the epidemic threshold at the regional level.

Out of 39 countries, 18 reported high or moderate intensity, and over half continued to report widespread influenza case activity.

Other indicators of influenza activity remained stable or decreased in most countries, while a few countries reported increases.

Various types of flu shots remain available in the U.S. and Europe as of March 9, 2022.

As of February 25, 2023, the Centers for Disease Control and Prevention confirmed about 173.26 million flu shots had been distributed in the U.S. during this season.
