Which disease comes under international surveillance –
**Core Concept**
International surveillance refers to the monitoring and reporting of diseases that have the potential to cause significant public health concerns, such as outbreaks, epidemics, or pandemics. This concept is crucial in global health security, allowing for timely interventions and control measures to prevent the spread of diseases.
**Why the Correct Answer is Right**
The correct answer is a disease that has been identified by the World Health Organization (WHO) as a priority for international surveillance. This designation is based on the disease's potential for rapid spread, severe impact on public health, and the need for coordinated global response. The WHO maintains a list of diseases under international surveillance, which includes conditions such as smallpox, poliomyelitis, and influenza.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it is not a disease that has been designated for international surveillance by the WHO.
* **Option B:** This option is incorrect because it is a disease that is not typically considered a priority for international surveillance, given its relatively low mortality rate and the availability of effective treatments.
* **Option C:** This option is incorrect because it is a disease that is primarily a concern in specific geographic regions and does not pose a significant threat to global public health.
**Clinical Pearl / High-Yield Fact**
One important aspect of international surveillance is the use of standardized case definitions and reporting protocols to ensure accurate and timely data collection. This allows for effective monitoring and response to disease outbreaks.
**Correct Answer: SARS. Severe Acute Respiratory Syndrome**
