Respiratory Syncytial Virus (RSV) activity in Maine is persisting later than expected this year, prompting updated guidance from the Maine Center for Disease Control and Prevention (Maine CDC). Clinicians and health care facilities are being urged to remain vigilant as RSV continues to circulate beyond its typical seasonal timeline.

The Maine CDC is recommending that clinicians maintain a high index of suspicion for RSV in patients presenting with clinically compatible respiratory illness. In response to the prolonged season, health care facilities are advised to continue offering RSV monoclonal antibody products to eligible patients and infants through April 30, extending beyond the usual March 30 end date.

This extension reflects an atypical pattern: RSV activity is peaking later and lasting longer than in recent years. For real-time updates on RSV and other respiratory viruses, providers can reference the Maine CDC Respiratory Virus Dashboard.
RSV remains a significant public health concern, particularly for infants and older adults. It is the leading cause of infant hospitalization in the United States and also poses serious risks to residents in long-term care settings.

National trends mirror what is being seen locally. According to updates shared by Dr. Gifford of AHCA/NCAL, RSV cases across the country are increasing and are expected to continue rising into April. Of particular concern is the growing rate of cases and hospitalizations among nursing home residents.
Despite this risk, vaccination uptake remains low. Currently, only about 1 in 5 eligible individuals have received the RSV vaccine, leaving many residents vulnerable to severe illness.

Facilities should prioritize:

• Vaccination of eligible residents
• Encouraging staff and visitors with respiratory symptoms to stay home
• Use of source control measures, such as masking, when illness is present

The risk of transmission may increase in the coming weeks as spring break and holiday gatherings bring more visitors—including young children—into contact with older adults in care settings.
