Seasonal flu is a contagious respiratory illness that can cause mild to severe illness and lead to serious complications—especially for older adults, young children, pregnant people, and those with certain health conditions. Each year, flu affects thousands of Connecticut residents and places added strain on families, schools, workplaces, and the healthcare system.
Flu spreads easily in communities, but there are steps you can take to help protect yourself and others. Getting a yearly flu vaccine, practicing good hand hygiene, staying home when sick, and knowing when to seek care can help reduce the spread of flu. The Connecticut Department of Public Health provides trusted, up-to-date information on flu prevention, symptoms, and vaccination for Connecticut residents.
