The New York State Department of Health is again encouraging New Yorkers to get the flu vaccine following an increase in influenza cases and hospitalizations in New York State.

State Health Commissioner Dr. James McDonald also recently declared that influenza is prevalent across the state and required health care workers who have not received this year’s flu vaccine to wear masks in certain health care settings.

“We are seeing a significant, sharp increase in influenza hospitalizations and cases in New York State, particularly in New York City and surrounding areas,” McDonald said. “If you haven’t already, today is a good day to get the current flu vaccine; it is safe and will lessen symptoms if you do get the flu. Now is the time to protect yourself and your loved ones, stay healthy and enjoy the upcoming New Year celebrations.”

During the week ending on December 21, there was an 86 percent increase in lab-confirmed influenza cases, and 648 hospitalized influenza cases were reported to the Department, a 57 percent increase from the 414 hospitalizations reported the week prior, the sixth consecutive week of increases.

Nine influenza-associated pediatric deaths have been reported nationally for the week ending Dec. 14; none were in New York state.

As of last week, five were hospitalized in the county with those numbers on an uptick.

The flu shot is available to those six months and older. Those aged 65 years and older, people with certain chronic medical conditions, young children and pregnant women are most in jeopardy of developing serious complications, which could require hospitalization and result in death.

In addition to getting the flu vaccine, simple preventative actions can help stop the spread of influenza and other respiratory viruses:

— Wash hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer.

— Avoid touching eyes, nose and mouth with unwashed hands.

— Avoid close contact with people who are sick.

— Stay home when sick.

— Cover cough or sneeze with a tissue, then throw the tissue in the trash.

— Clean and disinfect frequently touched objects and surfaces.
