The recent measles outbreak in Philadelphia has raised significant health concerns, highlighting the critical importance of vaccinations and the risks associated with non-compliance to public health guidelines. This outbreak, which began last month, has already resulted in at least eight confirmed cases.
The initial case was traced back to a child who had recently returned from overseas and was admitted to the Children’s Hospital of Philadelphia (CHOP) with what was later identified as measles. The Philadelphia Department of Public Health has classified this as an “imported” case but has not disclosed the specific country of origin.Â
The situation escalated when the infection spread within CHOP, affecting three more individuals, including a parent-child duo. Notably, the child, who had not been vaccinated against measles, was sent to a day care facility, Multicultural Education Station, despite being under quarantine instructions.
This lapse led to four more people at the day care contracting the disease. The spread of the infection in this manner underscores the challenges public health officials face in containing such highly contagious diseases, especially when quarantine protocols are not strictly followed.Â
A critical point to note is that none of the individuals diagnosed in this outbreak were immune to measles. This lack of immunity was due to either a lack of vaccination or no prior contraction of the disease. The Philadelphia Department of Public Health, while withholding specific details about the patients’ ages or vaccination status, has emphasized the role of the measles-mumps-rubella (MMR) vaccine in preventing such outbreaks.Â
The outbreak has had tangible impacts on the local healthcare system, with four additional hospital admissions, apart from the two already hospitalized cases. Philadelphia hospitals are now on high alert for new cases, given the highly contagious nature of measles.
An infected person can infect up to 90% of close contacts who are not immune. The virus can remain airborne and infectious for up to two hours after an infected person leaves an area, adding to the challenge of controlling its spread.Â
Dr. Doug Thompson, Chief Medical Officer at St. Christopher’s Hospital for Children in Philadelphia, revealed that the hospital has treated three measles patients, all between 1 and 2 years old, none of whom had been vaccinated. Measles typically presents with symptoms like high fever, cough, runny nose, red, watery eyes, and a characteristic red, blotchy rash. The disease can lead to severe complications, including pneumonia and brain swelling, particularly in unvaccinated individuals.Â
The outbreak has brought to light the importance of vaccination. The Centers for Disease Control and Prevention (CDC) states that one dose of the MMR vaccine is 93% effective, and two doses are 97% effective in preventing measles, with lifelong protection. In Philadelphia, at least 93% of children have been fully vaccinated against measles by age 6, following the recommended vaccination schedule.Â
For those exposed to measles and not immune, timely vaccination within 72 hours or an immune globulin injection within six days of exposure can prevent infection. The recent decline in vaccination rates, fueled by misinformation about vaccine safety, opposition to vaccination requirements, and the COVID-19 pandemic, has been a contributing factor to such outbreaks. The U.S. had effectively eliminated measles in 2000, but occasional outbreaks, often originating from other countries, continue to occur, as seen in Ohio and New York in recent years.Â
This outbreak in Philadelphia serves as a stark reminder of the contagious nature of measles and the critical role of vaccinations in public health. It highlights the need for continued vigilance and adherence to vaccination schedules to prevent such outbreaks and protect public health.Â
