Are You Flying Into a Flu Season?
The World Health Organization (WHO) published its Influenza Update #390 on March 29, 2021, which stated 'despite continued or even increased testing for influenza in some countries, global influenza activity remained at lower levels than expected for this time of the year.'
Worldwide, 'influenza B detections accounted for most of the very low numbers of detections reported.'
The WHO says the 'current influenza surveillance data should be interpreted with caution as the ongoing COVID-19 pandemic has influenced to varying extents health-seeking behaviors, as well as testing priorities and capacities in Member States.'
In the Northern Hemisphere's temperate zone, which includes Canada, Mexico, and the USA, influenza activity remained below the baseline. However, sporadic detections of influenza A and B viruses continued to be reported in some countries.
Furthermore, in the Caribbean and Central American countries, no influenza detections were reported last week.
In the Southern Hemisphere's temperate zone, such as Brazil, influenza activity was reported at an inter-seasonal level since this flu season is just starting.
For the remainder of the 2020-2021 flu season, the U.S. CDC recommends using any licensed, age-appropriate flu vaccine as an option for vaccination this season. These include injectable flu vaccines, live attenuated influenza vaccines, or nasal spray.
Everyone 6 months and older should get a flu shot every season, with rare exceptions. Vaccination is essential for people at high risk of serious complications from influenza, says the CDC.
