United States: Philadelphia is facing a concerning outbreak of measles, with six identified locations experiencing a surge in cases, prompting worry among residents and health authorities in the United States. The city’s health department reported a series of measles cases in these locations starting in late December 2023.
Health officials initially announced five affected locations in mid-December, with an additional location added just two days before Christmas. The recent update from authorities highlights a cluster of cases mainly among unvaccinated individuals, with the Children’s Hospital of Philadelphia recording the first cluster.
As of January 5, there were six confirmed cases and three presumed cases, according to reports from 6ABC. The crisis reportedly began after an infected person disregarded quarantine protocols after visiting a daycare facility, subsequently leading to multiple cases across the nation.

City officials emphasized the need for anyone potentially exposed to measles to self-quarantine, stay at home, and avoid contact with others, as advised by 6ABC News. They also provided a list of locations at risk of exposure compiled by 6ABC News, including:
- Multicultural Education Station Day Care at 6919 Castor Ave
- Children’s Hospital of Philadelphia Emergency Room at 3401 Civic Centre Blvd
- Jefferson Health building at 33 S 9th/833 Chestnut St
- St Christopher’s Hospital for Children Emergency Department
- Nazareth Hospital Emergency Room
- St Christopher’s Hospital for Children inpatient unit 5 North
Health officials urged those who visited these places on specific dates to seek medical advice, especially if they lack immunity to the measles vaccine or are experiencing symptoms.
Additionally, individuals should inform healthcare providers about potential measles exposure when seeking medical assistance.
Authorities stressed the importance of infected individuals staying home to prevent spreading the virus to vulnerable populations.
Measles is a highly contagious virus, with about 90% of unvaccinated individuals exposed to it contracting the disease, according to Philadelphia Health Commissioner Dr Cheryl Bettigole. Symptoms include fever, runny nose, cough, puffy eyes, and a characteristic rash. In severe cases, measles can lead to complications like brain infections, pneumonia, and even death.

Dr Bettigole urged immediate vaccination against measles for those not immunized, especially children aged 12 months and older, and advised following public health guidelines to prevent further exposure to the disease.
