Hamilton Investigates Measles Case After Exposures at Elementary School and Children’s Hospital
Public health officials in Hamilton are investigating a confirmed case of measles in a child, with potential exposures reported at a local school and hospital. Hamilton Public Health Services announced the positive case on Friday, warning that residents may have been exposed to the highly contagious virus at Holy Name of Jesus Catholic Elementary School and McMaster Children’s Hospital Emergency Department over the past two weeks.
The exposures are believed to have occurred at the school between February 4 and February 7, from 9 a.m. to 6:10 p.m., and at the hospital’s emergency department on February 10, between 11:59 a.m. and 12:29 p.m. The health agency has already contacted individuals identified as potential contacts and is urging others to monitor for symptoms.
Measles, a serious respiratory infection, spreads easily among those who are not fully vaccinated or have not previously contracted the virus. Infants under one year old, pregnant individuals, and people with weakened immune systems are at heightened risk of severe complications. Symptoms typically appear seven to 21 days after exposure and include high fever, cough, runny nose, red and watery eyes, and a red, blotchy rash that develops three to seven days after initial symptoms.
Hamilton Public Health Services is advising residents to check their immunization records to ensure they and their family members are up to date with measles vaccinations (MMR or MMRV). Two doses are generally recommended for anyone born in or after 1970. Those who are not fully vaccinated are being urged to avoid contact with high-risk individuals and settings, including healthcare facilities, childcare centers, and schools.
Students and childcare workers who were exposed and lack up-to-date vaccination records will be excluded from these settings for 21 days following exposure. Anyone experiencing symptoms is advised to stay home and avoid public spaces, including work, school, and childcare.
This case follows a recent measles exposure alert in York Region, where an infected individual visited two busy locations. Health officials are emphasizing the importance of vaccination to prevent further spread of the virus.
