Norovirus Outbreak Sweeping Across Connecticut: Infectious Disease Doctors Warn of Vomiting and Diarrhea
Connecticut is currently experiencing a widespread outbreak of norovirus, a highly contagious stomach bug that causes vomiting and diarrhea. Infectious disease doctors are urging people to take precautions such as washing their hands regularly and using bleach to keep surfaces clean.
According to Dr. Scott Roberts, associate medical director for infection prevention at Yale New Haven Hospital, norovirus typically appears during the winter months and seems to be peaking now. Last year, the peak occurred in March, so it remains to be seen if the same pattern will repeat this year. However, anecdotal reports from patients in pediatric settings and lab data suggest that norovirus cases are on the rise.
While the current outbreak is not as severe as last year’s, it is still a cause for concern. Dr. Roberts explains that norovirus can cause infection with just a few viral particles, making it highly contagious. Unlike other viruses, alcohol-based sanitizers like Purell are ineffective against norovirus. Specialized cleaners such as bleach are required to kill the virus, making it difficult to eradicate once it spreads in congregate settings.
Dr. Ulysses Wu, chief epidemiologist and system director for infectious diseases at Hartford HealthCare, reveals that norovirus is not limited to Connecticut but is also spreading throughout the Northeast, mid-Atlantic states, Michigan, and the West. It is commonly found in closed settings like cruise ships, military bases, college campuses, nursing homes, schools, and daycares. Norovirus is considered the most common cause of epidemic gastrointestinal disease worldwide, resulting in approximately 900 deaths and 450,000 emergency department visits in the United States each year.
The key symptom of norovirus is vomiting, although diarrhea may accompany it. Symptoms typically appear within 12 to 48 hours after exposure, making it easy to identify the virus. Dr. Roberts emphasizes the importance of avoiding contact with infected individuals, washing hands with soap and water, disinfecting surfaces, and using separate bathrooms if someone in the household is infected. The virus spreads through fecal contact and unwashed food, so it is crucial to clean doorknobs, countertops, and ensure that food is properly cooked.
Dr. Roberts also notes that people are not contagious until they begin vomiting but can continue shedding the virus for a couple of days after symptoms subside. It is recommended to be asymptomatic for at least 72 hours before resuming normal activities or sending children back to school.
In conclusion, the norovirus outbreak in Connecticut serves as a reminder of the importance of practicing good hygiene and taking necessary precautions to prevent the spread of infectious diseases. By following proper handwashing techniques, using bleach to disinfect surfaces, and maintaining food safety measures, individuals can protect themselves and others from this highly contagious stomach bug.
