Seasonal Outlook

Influenza Virus circulation appears to be following the expected pattern of spread throughout the US, beginning in the south, progressing north and west. Current increasing positivity indicates we can expect typical seasonal Influenza activity.
RSV positivity is seen to slowly circulate to northern states, consistent with a nationwide low and slow circulation rate compared to previous respiratory seasons. An increase in cases should be expected as we progress through late Autumn/early winter.
