Influenza A, Respiratory syncytial virus (RSV), and COVID-19 virus (SARS-CoV-2) are circulating at unusually high levels in the community.

Influenza, also known as the flu, is a viral infection that affects the respiratory system and is highly contagious. It can lead to severe complications, including pneumonia, particularly in vulnerable individuals.

RSV is a common respiratory virus that can cause mild to severe illness in people of all ages and can be especially dangerous for young children, elderly adults, and people with compromised immune systems.

COVID-19 is a novel coronavirus that was first identified in Wuhan, China in 2019 and has since become a global pandemic with millions of cases and hundreds of thousands of deaths reported worldwide. Primarily spread through respiratory droplets, it can lead to severe illness and death, especially in older adults and those with underlying health conditions.

The volume of COVID-19 virus testing has remained constant, approximately 1,250 tests/day.  The positivity rate remains relatively high, fluctuating between 5 to 15% on a daily basis.
