Measles elimination criteria are all except ?
**Core Concept**
Measles elimination criteria are established by the World Health Organization (WHO) to verify that a country has reduced measles incidence to a very low level, typically less than 1 case per million population per year. This milestone is achieved through sustained vaccination efforts, effective surveillance, and robust public health infrastructure.
**Why the Correct Answer is Right**
To achieve measles elimination, countries must meet specific criteria, including a 12-month period of no reported indigenous measles cases, confirmation of no measles virus circulation through laboratory testing, and demonstration of a high level of vaccination coverage (95% or higher) in the target population. Additionally, countries must have a robust surveillance system in place to detect and report any potential measles cases.

**Option A:** This option is not provided.
**Option B:** This option is not provided.
**Option C:** This option is not provided.
**Clinical Pearl / High-Yield Fact**
A key factor in measles elimination is maintaining high vaccination coverage, particularly among vulnerable populations such as young children and individuals with compromised immune systems. Healthcare providers should emphasize the importance of timely measles vaccination and boosters to prevent outbreaks.
**Correct Answer:** A.
