Missouri health officials have received three reports of influenza-associated deaths this season.

The Missouri Department of Health and Senior Services on Monday said the number of influenza cases in Missouri recently surpassed 1,500 with the state receiving three reports of influenza-associated deaths this season.

“For those who haven’t already been vaccinated, it is important to know that it’s not too late,” said Dr. Randall Williams, director of the Missouri Department of Health and Senior Services. “We are approaching the peak of flu season, so now is still a great time to protect yourself and others around you by being vaccinated.”

The department of health recommends a yearly flu vaccine for everyone six months and older, especially individuals either at high risk of having flu-related complications or because they live with or care for someone more susceptible to developing flu-related complications —children 5 and under, adults older than 65, pregnant women and those with weakened immune systems or chronic conditions such as asthma, diabetes or heart disease.
