Surge in hospitalizations
State data show flu hospitalizations in Ohio are running higher than at the same point in last year’s already severe season. ODH Director Dr. Bruce Vanderhoff said that in the week ending January 3, Ohio hospitals treated 1,911 flu patients, up from 1,305 during the comparable week last year.
Health officials note that flu activity typically rises around the holidays but say the current spike is steeper than expected. Hospitals are preparing for continued strain as flu season is expected to stretch into February and possibly the spring.
New “super flu” strain
Epidemiologists point to a strain known as H3N2 Clade K, informally referred to as the “super flu,” as a key driver of the surge. Many Ohioans have not previously been exposed to this version of the virus, leaving a larger share of the population susceptible to infection at the same time.
While this strain appears to spread efficiently and is contributing to more people getting sick, early indications suggest that vaccination still reduces the risk of severe illness and hospitalization. Officials caution that the “super flu” label reflects its impact on health systems, not that it is uniformly deadly for most patients.
Who is most at risk
ODH and federal health guidance highlight several groups at heightened risk for serious flu complications, including hospitalization and death. These include:
– Adults 65 and older.
– Children under 5, especially those younger than 2.
– People with chronic conditions such as asthma, heart disease, diabetes, or weakened immune systems.
– Pregnant women and residents of nursing homes or long-term care facilities.
Officials say pediatric cases are a particular concern after at least one flu-related child death reported in the state this winter. Caregivers are being urged to watch for rapid breathing, persistent high fever, or difficulty staying hydrated in children and to seek prompt medical care when warning signs appear.
Vaccination still critical
Despite the emergence of the “super flu” strain, ODH stresses that vaccination remains the best tool to prevent severe outcomes. While this year’s flu shot may not fully block infection from every circulating strain, data suggest it significantly lowers the risk of hospitalization and death if a vaccinated person gets sick.
The Centers for Disease Control and Prevention recommends that everyone 6 months and older receive a flu vaccine each season, ideally by late fall but as long as viruses are circulating. In Ohio, recent estimates show fewer than half of adults and children have gotten vaccinated, leaving a large portion of the population unprotected heading into the peak of flu season.
Steps residents are urged to take
Health authorities are calling on residents to combine vaccination with everyday precautions to slow the spread of the “super flu.” Recommended steps include:
– Get vaccinated: Make an appointment with a doctor, pharmacy, or local health clinic as soon as possible; protection builds about two weeks after the shot.[3][7]
– Stay home when sick: Avoid work, school, and gatherings if you have fever, cough, sore throat, or body aches to prevent exposing others.
– Practice hand hygiene: Wash hands often with soap and water for at least 20 seconds, or use an alcohol-based sanitizer when soap is unavailable.[1][5]
– Cover coughs and sneezes: Use a tissue or cough into your elbow, then discard tissues and clean your hands.
– Improve indoor air: Increase ventilation or use air filtration when possible, especially in crowded or shared spaces.
Officials warn that the coming weeks will be critical in determining whether Ohio’s “super flu” wave intensifies or starts to recede. They say collective action—especially getting the flu shot and staying home when ill—will play a major role in protecting vulnerable residents and keeping hospitals from becoming overwhelmed.
