Central Ohio's measles outbreak improving, not over

What's happening: Columbus Public Health (CPH) officials believe greater awareness of the outbreak and a surge in MMR (measles, mumps and rubella) vaccinations could be contributing to the decline, a spokesperson tells Axios.

• The health department administered 200 MMR shots last month, nearly double the rate of December clinics in recent years.

What's next: To officially end an outbreak, two virus incubation periods, or 42 days, must pass after the last infected person developed a rash.

• That would make early February the earliest CPH could declare our local outbreak over — if no other cases are reported.

Flashback: Ohio's last measles outbreak, among the Amish community northeast of Columbus, lasted four months and infected 383 people in 2014.
