A measles outbreak in Philadelphia has now reached 9 confirmed cases as of January 17th, 2024. Health officials are scrambling to contain the further spread of the highly contagious virus through contact tracing and pushing vaccinations. However, the outbreak has already spread to nearby Camden County, New Jersey, highlighting the challenges of containing the outbreak in a dense metropolitan area.
Outbreak Originated from Unvaccinated Toddler at Daycare
The outbreak is believed to have originated from an unvaccinated toddler who attended a daycare center in the East Germantown neighborhood of Philadelphia. The first cases were detected in early January when the toddler and several other children at the daycare developed symptoms.
Due to low vaccination rates, the virus was able to spread rapidly among unvaccinated children. Vaccination rates for MMR (measles, mumps, rubella) have dropped over the past several years due to COVID-19 disruptions and increasing vaccine hesitancy. Public health experts have warned that low vaccination rates make communities vulnerable to measles outbreaks.
“When you see measles looming in the foreground like this, that lets you know your protection against diseases is lower than it should be,” said Dr. Ala Stanford, founder of the Black Doctors COVID-19 Consortium.
Health Officials Declare Public Health Emergency
On January 17th, Philadelphia health officials declared a public health emergency due to the worsening measles outbreak. This declaration allows health officials greater authority to implement control measures like excluding unvaccinated children from schools.
Health officials also announced new recommendations for Philadelphians due to the declaration:
- Get vaccinated – All children should receive the standard 2-dose MMR vaccine schedule. Adults should make sure they have received the recommended measles vaccines.
- Be aware of measles symptoms – Symptoms typically appear 10-14 days after exposure and include high fever, cough, runny nose, and red eyes, followed by a rash breakout. Contact your doctor if you develop these symptoms.
- Isolate if exposed – If you suspect you have been exposed to measles, isolate yourself from others to avoid further spread.
In addition to the public health emergency declaration, health officials are partnering with health providers throughout Philadelphia to offer additional vaccination clinics and outreach.
Measles Spreads to Nearby Camden County
On January 16th, health officials in neighboring Camden County, New Jersey announced a confirmed measles case in a resident with links to the Philadelphia outbreak. The individual was unvaccinated and contracted measles after visiting a healthcare facility that had documented measles exposure.
Due to the interconnectedness of the Philadelphia and South Jersey metropolitan region, health experts had warned it was only a matter of time before the outbreak spread across state lines.
“Measles outbreaks illustrate the importance of maintaining high vaccination rates and herd immunity,” said Karen Panetta, dean of graduate engineering education at Tufts University. “Measles doesn’t care about state or country borders.”
With over 1,200 healthcare facilities and heavy transportation links between Philadelphia and Camden County, health officials are preparing for additional spread. Contact tracing efforts are underway in Camden County to identify and isolate other potentially exposed individuals.
Low MMR Vaccination Rates Created Conditions for Outbreak
According to the CDC’s latest published data, only 68.5% of Pennsylvania toddlers aged 19-35 months old had received their 2-dose MMR vaccine series as of 2020. This is far below the roughly 93-95% vaccination rate needed to provide herd immunity protection against highly contagious diseases like measles.
Experts attribute declining childhood vaccination rates to various factors, including:
- Disruptions to routine healthcare during the COVID-19 pandemic
- Increasing vaccine misinformation and disinformation deterring some parents
- Complacency regarding the need for vaccines as diseases become less common
“When there is an outbreak after low vaccination rates, parents should consider it a wake-up call about the importance of timely vaccination,” said actress Jennifer Garner, a vaccination advocate.
Health officials emphasized that vaccines remain safe and effective, and urged parents to get their children caught up on routine immunizations. Maintaining herd immunity protects those unable to get vaccinated for medical reasons.
What’s Next: Efforts to Contain Outbreak and Push Vaccinations
As long as unvaccinated pockets of the population remain, measles has the potential to spread, especially within close-knit communities. Health officials will continue contact tracing to find and isolate all potentially exposed individuals to limit further viral transmission.
In addition to contact tracing, health officials plan continued efforts to improve MMR vaccination rates across Philadelphia and the surrounding region to limit spread and protect vulnerable groups:
- Partnering with health providers, religious institutions, and community organizations to set up vaccination clinics
- Public outreach campaigns to promote vaccination awareness
- Working with local governments to incentivize vaccination through public policy
- Excluding unvaccinated students from schools under the public health emergency declaration
“The most effective way to protect our communities is to ensure vaccination coverage is over 93 percent – the threshold for herd immunity,” said Philadelphia Health Commissioner Dr. Cheryl Bettigole.
Bringing MMR vaccination rates to 93% and above will likely take months to years of concerted effort. In the meantime, isolated measles outbreaks remain a risk until herd immunity can be firmly re-established across every community.
Measles at a Glance
| Symptoms | Fever, cough, runny nose, red eyes, rash |
|---|---|
| Transmission | Airborne droplet spread |
| Contagious Period | 4 days before rash onset to 4 days after |
| Incubation Period | 7-14 days |
| Treatment | Supportive care, vitamin A |
| Preventive Vaccine | MMR – 2 doses |
With concerted vaccination efforts and community awareness, the current outbreak can eventually be fully contained. But health experts say now is the time for decisive action before measles gets an even greater foothold across Philadelphia and beyond. Maintaining herd immunity remains the most effective long-term, population-level safeguard against measles resurgence.
