An unvaccinated Macon County resident has tested positive for measles, and the patient is now isolating at home while unvaccinated close contacts quarantine. The case brings Georgia's 2026 measles total to 22, health officials say, a number that has already more than doubled the 10 cases the state logged in all of 2025.
The Georgia Department of Public Health confirmed the case, according to 41NBC, which reported that the resident has no known travel history but had contact with a confirmed measles case from Pennsylvania. That state is in the middle of an outbreak that has surpassed 1,100 cases, and DPH is now working to identify others who may have been exposed in Georgia as a result of the contact.
As Atlanta News First also reported, the resident remains isolated at home while any unvaccinated close contacts quarantine separately. Measles is notoriously contagious: the virus can linger in the air for up to two hours after an infected person has left a room, and symptoms typically appear seven to 14 days after exposure, though the incubation period can stretch to 21 days, per the same outlet's report.
Georgia's Case Count Keeps Climbing
Georgia's 22 cases so far in 2026 represent more than double the 10 cases the state saw during all of 2025, according to WRDW. The jump mirrors a broader national rise in measles activity this year, though the scale of that national increase is described differently depending on the source: CBS News Atlanta has reported more than 3,200 U.S. cases in 2026, while a separate CDC data snapshot put the figure at 2,263 cases reported across 45 jurisdictions.
Pennsylvania's outbreak, the one tied to the Macon County contact, has been described by the Associated Press as the largest state-level measles outbreak in decades, with more than 1,000 cases reported there this year. Pennsylvania's health department has responded with potential-exposure notices, vaccination clinics and outreach efforts, according to the state's health agency.
Vaccination Gaps Behind the Spread
Public health officials have pointed to vaccination gaps as a key factor in measles' return. During the 2025-2026 school year, 89% of Georgia's kindergarten-age population received routine vaccines, including the MMR shot, according to GPB, which also reported just over 6,000 vaccine exemptions among Georgia kindergartners that same year. A separate report from Macon.com put the state's kindergarten MMR vaccination rate at under 87%, well below the 95% threshold generally associated with reliable herd immunity.
The CDC recommends children receive two doses of the MMR vaccine, the first between 12 and 15 months of age and the second between ages 4 and 6, per 41NBC's report. 41NBC reported that one dose provides about 93% protection against measles, with two doses raising that to about 97%.
Health officials continue to urge unvaccinated residents to get the MMR vaccine as Georgia's case count climbs. DPH has not released further details on the Macon County case, and it remains unclear how many unvaccinated close contacts are currently under quarantine or whether additional cases have been identified in connection with this exposure.
