Respiratory Viral Season Shows Significant Decline

As you can see from the two graphs below, respiratory viral season is on the way out!
Our RSV percent positives have dropped to below 10% for a few weeks now, indicating the end to the season. We are still seeing some respiratory adenovirus and some parainfluenza 3, but these are at low levels.
We will continue to report for the next few weeks and then take a break for the summer. We will be back reporting in October and staying alert for any unusually early our atypical trends.
Have a great end of spring and summer!

Viral Isolates Update

As you can see from the graphs below, the respiratory viral season is slowing down. We are running below 15% positivity for RSV and these upcoming weeks are expected to bring positivity rates down below 10% (the end to endemic disease). Interestingly, as RSV is on the decline, parainfluenza is increasing. We have had parainfluenza type 3 isolated in moderate numbers from most of our reporting sites. Parainfluenza type 3 is a common cause of bronchiolitis and pneumonia in infants and young children and may resemble RSV bronchiolitis. Parainfluenza types 1 and 2 are the viruses usually associated with viral croup.
We are still seeing some influenza A and B, but as with RSV, these numbers are declining as well.
Stay tuned for updated numbers and percent positive RSV to be updated later in the week.
