Once considered eliminated in the US, measles is spreading again. Rising case numbers across the nation highlight the growing impact of declining vaccination rates and renewed challenges for public health.
A recent NPR article reports that measles cases are rising nationwide, with the CDC confirming 1,596 cases so far this year, the highest annual total in more than 30 years. Experts warn the actual number may be closer to 5,000, as outbreaks continue in several states.
South Carolina is currently managing an outbreak that has led to quarantines for more than 100 schoolchildren following exposure to measles. In the Southwest, a large outbreak along the Arizona and Utah border continues to grow. Utah has reported 56 cases this year with multiple hospitalizations. Wastewater testing indicates that the virus may be more widespread than previously known. Arizona has confirmed 77 cases so far, including 14 new ones in the last week, while Minnesota has reported 20 cases this year.
All told, the CDC has confirmed 44 measles outbreaks in 41 states this year. The vast majority of cases were in people who were unvaccinated; 27% percent have been in children under the age of 5. About 1 in 8 measles cases have resulted in hospitalization.
Before widespread vaccination, measles infected nearly every child in the US and caused 400 to 500 deaths annually. The disease was declared eliminated in 2000, but national vaccination coverage has since slipped to 92.5 percent, below the 95 percent threshold needed to prevent outbreaks. Health experts warn that falling vaccination rates have created pockets of vulnerability across the country, allowing measles to regain a foothold.
Measles remains one of the most contagious viruses known, capable of infecting up to 18 unvaccinated individuals from a single case. The virus can linger in the air for up to two hours after an infected person leaves a room. Officials continue to urge families to stay up to date on the recommended measles, mumps, and rubella (MMR) vaccine to protect themselves and their communities.
While Maryland had largely avoided outbreaks, the Maryland Daily Record reports, Kent County’s kindergarten vaccination rate for measles, mumps, and rubella (MMR) stands at 88%, below the 95% threshold needed for herd immunity and the lowest in the state.
From The Daily Record article:
We’re very concerned about any drop in vaccination rates, especially related to measles, because we know that measles is one of the most infectious viruses that we’re aware of. One of the things I don’t think our community understands is how infectious measles is, said Kent County Health Department Health Officer William Webb.
As previously covered by MACo, according to health experts, vaccination remains the most effective defense against measles, and county governments can play a leading role in the effort. Local health departments are central to preventing and managing disease outbreaks. From monitoring cases to organizing vaccination clinics and community outreach, they are equipped to respond swiftly and effectively. Close coordination between health departments, county officials, and community partners strengthens public trust and supports higher vaccination rates where they’re most needed.
