Current RSV Outbreak Status in North and South Carolina
I cannot provide real-time outbreak surveillance data, as the evidence provided consists of historical guidelines and research studies rather than current epidemiological reports.
What the Evidence Shows About RSV Seasonality in the Carolinas
Historical RSV patterns in North Carolina demonstrate significant regional and temporal variation, with activity detected nearly year-round in some areas. A prospective study across five regions in North Carolina from 2003-2006 found RSV was detected during all but three months of the study period, with seasonal onset typically occurring in October-November and lasting 6-7 months 1.
Key Regional Patterns
North Carolina exhibits longer RSV seasons than the national average, with the greatest percentage of positive tests (33.8%) occurring in January 1.
The Southeast United States, including the Carolinas, typically experiences earlier RSV season onset compared to other regions, with epidemics beginning earlier in Florida and the Southeast before spreading north and west 2, 3.
National prepandemic patterns (2017-2020) showed RSV seasons beginning in October, peaking in December, and ending in April 2.
Post-Pandemic Considerations
RSV seasonality has been disrupted since the COVID-19 pandemic, with unusual patterns emerging:
The 2021-22 season began in May, peaked in July, and ended in January—completely out of typical winter timing 2.
The 2022-23 season started in June and peaked in November, suggesting a gradual return toward prepandemic patterns but with continued variability 2.
Clinicians should remain aware that off-season RSV circulation may continue despite trends returning toward historical patterns 2.
How to Obtain Current Outbreak Information
For real-time RSV surveillance data specific to North and South Carolina:
Monitor the CDC's National Respiratory and Enteric Virus Surveillance System (NREVSS), which tracks RSV test positivity rates at state and regional levels 2, 3.
Contact state health departments (North Carolina Department of Health and Human Services or South Carolina Department of Health and Environmental Control) for current local surveillance data.
Review CDC's weekly respiratory virus surveillance reports, which define RSV epidemic periods as weeks when ≥3% of PCR tests are positive for RSV 2.
Clinical Implications
Given the historical patterns and recent variability, healthcare providers in the Carolinas should:
Maintain heightened awareness for RSV from September through April, with peak vigilance during November-January 1, 2.
Consider RSV testing for high-risk patients (infants, elderly, immunocompromised) presenting with respiratory symptoms even outside traditional winter months 1.
Implement appropriate infection control measures including hand hygiene, contact precautions with gowning and gloving when handling infected patients or their secretions 4.
