**Core Concept**
The World Health Organization (WHO) maintains a list of diseases under international surveillance to facilitate global response to emerging infectious diseases. This list includes diseases that have the potential to cause significant morbidity and mortality, and for which there is a need for coordinated international action.

**Why the Correct Answer is Right**
The correct answer is a disease that meets the WHO's criteria for international surveillance. This typically involves diseases that have a high potential for transmission, are easily spread between people, and have significant public health implications. The WHO monitors these diseases closely and provides guidance and support to countries to help them prevent and control outbreaks.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a disease that is typically considered to have significant public health implications or a high potential for transmission. While it may be a serious disease, it is not typically considered to be under international surveillance.

**Option B:** This option is incorrect because it is not a disease that is currently under international surveillance by the WHO. The WHO's list of diseases under international surveillance is regularly updated, and this disease may not be on the current list.

**Option C:** This option is incorrect because it is a disease that is typically considered to have a low potential for transmission and is not typically considered to be under international surveillance.

**Option D:** This option is incorrect because it is a disease that is typically considered to be well-controlled in most countries and is not typically considered to be under international surveillance.

**Clinical Pearl / High-Yield Fact**
The WHO's list of diseases under international surveillance is regularly updated to reflect changes in the global disease landscape. It is essential for healthcare professionals to stay up-to-date with the current list to ensure they are aware of the diseases that require international coordination and response.

**Correct Answer:** SARS-CoV-2 (COVID-19)
