February, 2024

The downward trend of Respiratory Syncytial Virus (RSV) cases has continued since reaching its peak in late December. Simultaneously, influenza numbers, which had been on an upward trajectory in late December, have started to level off as we enter February. This pattern suggests a noteworthy shift in the prevalence of respiratory illnesses with RSV maintaining a declining trend while influenza cases appear to be stabilizing.

The volume of SARS-CoV-2 virus testing has remained consistent at approximately 500 tests per day throughout January, with a positivity rate ranging between 3% and 5%. See www.cdc.gov/coronavirus/2019-ncov for the most recent updates.
