(Over 1,200 casesâand countingâcould turn this summer into a public health nightmare)
1. Unprecedented Outbreak in 2025
As of July 2025, the U.S. has confirmed 1,288 measles cases across more than 20 statesâmaking it the largest national outbreak in over 30 years.
Among these, three deaths have been reportedâthe first in over a decade. These cases have been traced back to schools, airports, summer camps, and religious gatherings.
đ âThis is not just a wake-up callâitâs a full-blown siren,â says Dr. Laura Donnelly, infectious disease specialist at NYU Langone. âWe havenât seen spread like this since the early â90s.â
The CDC confirms the measles virus is currently circulating in states like Texas, New Mexico, Ohio, and Michiganâlargely due to local vaccine hesitancy and declining MMR vaccination rates.
2. Hidden Threats to Children, Pregnant Women & Vulnerable Families
Measles is more than a rash and feverâitâs a highly contagious virus that can lead to pneumonia, brain swelling (encephalitis), hearing loss, and even death.
Whoâs most at risk?
-
Children under 5
-
Pregnant women
-
People with weakened immune systems
According to the CDC:
-
1 in 20 children who get measles develop pneumonia
-
1 in 1,000 may experience brain swelling
-
1 to 3 in 1,000 may die
đ§ One pediatric ICU case involved a 7-year-old girl in Ohio who developed swelling in her brain and had to be placed in a medically induced coma. Doctors say she may suffer permanent neurological damage.
This outbreak is differentâbecause even vaccinated communities are being tested. Herd immunity is dropping, and unvaccinated individuals are becoming virus amplifiers.
3. Summer Travel & Camps Are Fueling the Spread
The outbreak, initially concentrated in urban districts, is now exploding through summer activities:
-
Day camps
-
Youth retreats
-
Family travel to national parks or amusement parks
Just last month, a case cluster in New Mexico was linked to a summer camp with 13 unvaccinated kids from four states.
đ§ł âFamilies often forget that international travelers are bringing measles strains to the U.S.,â says Dr. Malcolm Reid, former CDC travel consultant. âYour kidâs cabin buddy mightâve flown in from a hotspot.â
With school right around the corner, back-to-school physicals are the last line of defenseâyet some districts have reported 40% of students are still unverified.
đĄ What You Can Do RIGHT NOW
đ Check your childâs vaccination records
-
Make sure theyâve received two doses of the MMR vaccine
-
The first dose is typically given at 12-15 months, the second at 4-6 years
đ§ Protect infants and at-risk family members
-
Babies under 12 months can’t get the MMR shotâkeep them away from crowded indoor spaces
-
Ask about vaccination status before daycare or family visits
đ§ł Get the facts before you travel
-
If you’re flying this summer, review CDCâs travel health notices
-
Many countries are also experiencing surgesâand even a layover could expose your child
