As of April 8, 2025, Knox County has reported a total of 14 confirmed measles cases. Seven of these cases involve Ohio residents and are linked to the initial case in the county. Those affected are currently isolated and their symptoms are being monitored.

Measles is known for its high contagion rate. The virus can spread from individuals without immunity before symptoms appear and can remain airborne for up to two hours after an infected person leaves a room. Symptoms typically emerge between 7 to 14 days post-exposure but may take up to 21 days.
The Ohio Department of Health notes that about one in five measles patients require hospitalization, with encephalitis occurring in approximately one out of every 1,000 cases, potentially leading to brain damage. Mortality rates range from one to three per 1,000 infected individuals despite medical care.
The Centers for Disease Control and Prevention advises that children receive two doses of the MMR vaccine starting at ages 12-15 months and again at ages 4-6 years. Travelers should ensure full vaccination prior to international travel. Infants aged 6-11 months should receive one dose before traveling, followed by two additional doses after their first birthday. Unvaccinated older children, adolescents, and adults should also receive the vaccine if they lack immunity evidence. The MMR vaccine is about 97% effective after two doses.
Individuals unsure of their vaccination status or unvaccinated should consult healthcare providers about receiving the MMR vaccine. For inquiries or appointments regarding measles or vaccinations, contact Knox County Community Health Center at 740-399-8008.
Anyone experiencing symptoms should stay home, avoid others, and contact their healthcare provider before visiting medical facilities.
