The unprecedented spike is a part of a broader viral surge as the U.S. grapples with four major viruses — norovirus, respiratory syncytial virus, influenza and COVID-19. Hospitals across the country are also feeling the strain, as emergency departments struggle to accommodate the rising number of patients.
Here are five more notes:
- The norovirus positivity rate surged to 28% the week of the New Year’s holiday, more than double the 13.5% peak from last year, according to CDC data. This marks the highest rate in over a decade.
- The Midwest and Northeast regions are seeing the highest transmission levels. Kansas, Michigan, Ohio and Minnesota are facing particularly high rates.
- Experts identify the new norovirus strain, Gll.17[P17], as the primary driver behind this surge. The strain has displaced the previous prominent strain, fueling rapid spread of the virus. The CDC notes the strains account for 70% of outbreaks this season.
- U.S. hospitals are feeling significant pressure, with reports of emergency departments operating at full capacity, especially in Minnesota. The state is experiencing the highest flu-related admissions in five years and some hospitals have resorted to repurposing surgical and mental health beds to accommodate the influx of patients.
- Experts predict that the “quademic” — norovirus, syncytial virus, influenza and COVID-19 — could worsen as hospitals are already overwhelmed. With more outbreaks likely, health systems are implementing stricter protocols including visitor restrictions and increased coordination between hospitals to maintain trauma care capacity.
