Follow along with us this respiratory season for updates every two weeks.

Respiratory syncytial virus continues to trend upwards. During the 2023-2024 respiratory season, influenza virus rose above the 2.5% baseline approximately six weeks after RSV. RSV crossed the 2.5% threshold the week of October 13th this year, suggesting influenza virus will cross this threshold the week of November 24th.

Influenza virus has started to increase the past few weeks. Positivity reached 1.9% during the week of November 10th through November 17th, up from 1.2% the week prior.

Mycoplasma pneumoniae decreased slightly at the beginning of November but has since rebounded slightly and continues to maintain over 5% nationally, with some states peaking as high as 15%. Unfortunately, there are no rapid antigen tests available for Mycoplasma pneumoniae, meaning PCR is the primary method for detecting this pathogen.
