To kick off the respiratory trends reports for the 2024-2025 season, we are going to look back at respiratory virus circulation over the summer months. Follow along with us this respiratory season for updates every two weeks.

Respiratory virus circulation is often quite low in the summer months, apart from rhinovirus/enterovirus and COVID-19 coronavirus. Rhinovirus/Enterovirus generally remains quite high throughout the year and as COVID-19 coronavirus has settled into a more regular circulation pattern, it seems to peak once in the summer and again in the winter.

While Enterovirus D68 is typically quite low, it seems to circulate and peak every other year. Symptoms vary from cold-like symptoms to severe disease, including acute flaccid myelitis (link to reference: https://www.cdc.gov/mmwr/volumes/73/wr/mm7304a1.htm).

As we head into the school year, we expect that respiratory syncytial virus (RSV) will be one of the next viruses to begin circulation.
