HANOVER, NH — Health officials in New Hampshire are investigating a potential measles exposure in Hanover. An international traveler who visited the area between June 20 and June 22, 2024, later tested positive for measles upon returning to their home country. While there are no confirmed cases in New Hampshire at this time, authorities are taking precautionary measures to inform the public and prevent further spread.
Potential Exposure Sites
During their stay, the traveler visited several public locations in Hanover, including:
- Dartmouth College campus (June 20-22)
- The Hanover Inn at 2 E Wheelock Street (June 20-22)
- Hanover Scoops at 57 S Main Street (June 20, 3 PM)
- Lou’s Restaurant and Bakery at 30 S Main Street (one meal on an unspecified date and time)
- Dartmouth Coach Bus from Hanover to Boston Logan Airport (June 22, time unspecified)
The New Hampshire Department of Health and Human Services (DHHS) is collaborating with Dartmouth College and other local authorities to gather more details and notify individuals who may have been exposed. Anyone who visited these locations during the specified times and is not immune to measles is advised to monitor for symptoms.
Understanding Measles
Measles is a highly contagious viral disease that spreads through respiratory droplets when an infected person coughs or sneezes. The virus can linger in the air and on surfaces for up to two hours.
Symptoms typically appear 7 to 14 days after exposure and include:
- High fever (which may spike above 104°F)
- Cough
- Runny nose
- Red, watery eyes
- Tiny white spots inside the mouth (Koplik spots)
- A red rash that usually starts on the face and spreads to the rest of the body
While measles is often mild, it can lead to serious complications such as pneumonia, encephalitis (brain swelling), and, in rare cases, death. Young children, pregnant women, and individuals with weakened immune systems are at higher risk.
Preventive Measures
The best protection against measles is vaccination. The Measles, Mumps, and Rubella (MMR) vaccine is highly effective, providing about 93% protection after one dose and 97% after two doses. The Centers for Disease Control and Prevention (CDC) recommends that:
- Children receive the first MMR dose at 12-15 months of age and the second at 4-6 years.
- Adults who are unsure of their vaccination status check with their healthcare provider.
Public Health Response
In response to the potential exposure, the DHHS has taken the following steps:
- Investigation and Notification: Identifying and contacting individuals who may have been exposed.
- Vaccination Clinics: Coordinating with healthcare providers to ensure access to the MMR vaccine.
- Public Education: Providing information about measles symptoms, prevention, and the importance of vaccination.
What You Should Do
If you were present at any of the identified locations during the specified times and are not vaccinated, the DHHS advises the following actions:
- Monitor for Symptoms: Watch for signs of measles for up to 21 days after potential exposure.
- Contact a Healthcare Provider: If symptoms appear, call ahead before visiting a medical facility to prevent possible spread.
- Check Vaccination Records: Ensure that you and your family members are up to date on the MMR vaccine.
- Limit Exposure: If you suspect you have measles, avoid public places and close contact with unvaccinated individuals, pregnant women, and those with weakened immune systems.
Conclusion
While New Hampshire has not yet confirmed any measles cases, health officials are working proactively to prevent an outbreak. Vaccination remains the most effective tool in stopping the spread of this highly contagious disease. Residents are urged to stay informed, verify their immunization status, and seek medical advice if they have concerns.
