HealthTrackRx Trend Update

As June concludes, respiratory virus circulation remains at a seasonal low, with most pathogens either reaching their lowest levels of the year or continuing to decline from higher late-spring activity. COVID-19 activity remains low at 1.3% by the end of June; however, rates are expected to increase heading into July, consistent with 2024 and 2025 seasonal patterns that showed COVID-19 incidence rising in late July and August. Rhinovirus/Enterovirus also typically increases in late summer to early fall, coinciding with the back-to-school season.

Parainfluenza Virus and Adenovirus continue to show moderate circulation, ending the month at 8.5% and 4.6%, respectively. Both viruses are expected to begin declining as we move into July. Although Rhinovirus/Enterovirus is currently at the low point for the summer, it remains the most prevalent respiratory virus nationally at 22.5%. This pattern is consistent with historical trends, as Rhinovirus/Enterovirus positivity can reach as high as 40% during peak circulation.
