Kenosha Medical Center and St. Catherine’s Medical Center have imposed visitor restrictions to reduce chances of spreading the H1N1 virus, known as swine flu.

Hospital officials on Tuesday said patient visitors would be limited to:

— Immediate family and caregivers offering emotional well-being and care.

— Those 18 and older, including visits to maternity and children’s units.

— Those free of flu symptoms, such as fever, vomiting, nausea and diarrhea.

The age restriction does not apply to youngsters seeking medical help.

Patients will have a say, when possible, on whether visitors who might be a risk would be admitted.

The limitation will be in effect until the flu risk to patients decreases.

A press release from the hospitals’ parent, United Hospital System, said their emergency rooms have seen a “significant” jump in patients with flu-like symptoms, especially in people younger than 18.

The release said the Wisconsin Hospital Emergency Preparedness Plan Council Region 7 Executive Committee and the federal Centers for Disease Control recommended temporarily changing visitor guidelines to help block the virus’ spread.

Officials from Aurora Medical Center in Kenosha couldn’t be reached for comment on their visitor rules.

Wheaton Franciscan-All Saints hospital in Racine last week imposed similar restrictions.

That facility, however, might be flexible when patients are critically ill or near death.

It also restricts the number of visitors per patient to two; mandates washing hands before and after visiting, and, in some cases, might demand visitors wear masks.

Tips on helping corral the virus:

— Wash hands often with soap and water; avoid touching eyes, nose and mouth.

— Cover your mouth and nose when sneezing or coughing.

— If sick, stay home from work.
