International Notification is must in the following except
First, I need to recall which diseases require international notification. The WHO's International Health Regulations (IHR) list certain diseases that must be reported. These include diseases like plague, cholera, yellow fever, smallpox, and others. The question is asking for the exception, so the correct answer would be a disease not on that list.
Common distractors could be diseases that are often confused with the listed ones. For example, hepatitis B might be a wrong answer if it's not in the IHR list. Or maybe a disease that's not communicable. Let me check the IHR list again. The IHR (2005) requires notification of three diseases: plague, cholera, and yellow fever. But in newer versions, maybe others are included, like Ebola or SARS. However, the traditional ones are the three. So if the options include a disease not in this list, like typhoid or hepatitis A, that would be the exception.
Assuming the options are A. Plague, B. Cholera, C. Yellow Fever, D. Typhoid, then the correct answer is D. Typhoid. So the explanation would need to detail why typhoid isn't on the list, while the others are. Also, explain the IHR criteria for notification. For the incorrect options, clarify why they are required to be reported. The clinical pearl would emphasize the three main diseases under IHR. Need to make sure the explanation is concise and fits the character limit.
**Core Concept**
International notification is mandated under the World Health Organization's International Health Regulations (IHR) for diseases with high transmissibility, severity, or risk of international spread. This includes plague, cholera, yellow fever, and newer additions like Ebola and SARS-CoV-2.
**Why the Correct Answer is Right**
The correct answer (e.g., **Option D: Typhoid Fever**) is not a Class I communicable disease under IHR. Typhoid fever, caused by *Salmonella typhi*, is not inherently a priority for international notification unless there's an outbreak with cross-border risk. IHR focuses on diseases with rapid global spread potential, such as airborne pathogens or vector-borne viruses.
**Why Each Wrong Option is Incorrect**
**Option A: Plague** β A Class I disease; caused by *Yersinia pestis*, itβs highly transmissible and fatal if untreated, requiring immediate reporting.
**Option B: Cholera** β Caused by *Vibrio cholerae*; its waterborne transmission and explosive outbreaks necessitate international alerts.
**Option C: Yellow Fever** β A viral hemorrhagic fever spread by mosquitoes; its potential for urban epidemics mandates global notification.
**Clinical Pearl / High-Yield Fact**
Remember the "3 Cs" for IHR-mandated diseases: **C**holera, **C**lassical plague, and **C**onvalescent-phase yellow fever. Modern additions include SARS, MERS, and Ebola. Avoid confusing typhoid with typhus (another
