Global Response to Emerging Infections Indian Medical PG Question 3: Disease usually not seen in a country but brought from abroad is:
- A. Exotic (Correct Answer)
- B. Endemic
- C. Epidemic
- D. Zoonotic
Global Response to Emerging Infections Explanation: ***Exotic***
- An **exotic disease** refers to a disease that is not native or usually found in a particular country or region but is introduced from abroad.
- This term highlights its **foreign origin** and rarity within the local population.
*Endemic*
- An **endemic disease** is one that is constantly present in a population or region with a relatively stable prevalence within that population.
- It describes a disease that is **native** to a specific area, not typically brought from abroad.
*Epidemic*
- An **epidemic** signifies a sudden increase in the number of cases of a disease in a population over a particular period, substantially exceeding what is normally expected.
- While it can be introduced from abroad, the definition focuses on the **rapid spread** rather than the origin itself.
*Zoonotic*
- A **zoonotic disease** is an infectious disease that has jumped from an animal to humans.
- This term describes the **mode of transmission** from animals, not necessarily its geographic origin or whether it's new to a country.
Global Response to Emerging Infections Indian Medical PG Question 4: All of the following conditions are immediate priorities in the WHO's "Vision -2020: The Right to sight" except:
- A. Cataract
- B. Epidemic conjunctivitis (Correct Answer)
- C. Onchocerciasis
- D. Trachoma
Global Response to Emerging Infections Explanation: ***Epidemic conjunctivitis***
- While **epidemic conjunctivitis** can cause significant discomfort and temporary vision impairment, it is generally **self-limiting** and rarely leads to permanent blindness.
- It was not identified as one of the top five global causes of avoidable blindness targeted by the Vision 2020 initiative.

- **Cataract** is the **leading cause of blindness** globally, accounting for approximately half of all cases.
- It is a highly treatable condition through surgery, making it a critical priority for Vision 2020.
*Onchocerciasis*
- Also known as **river blindness**, onchocerciasis is a parasitic disease that causes severe visual impairment and blindness.
- It is a significant public health problem in several regions, particularly in Africa, and was a key focus of Vision 2020 due to its widespread impact and the availability of preventive chemotherapy.
*Trachoma*
- **Trachoma** is the **leading infectious cause of blindness** worldwide, caused by *Chlamydia trachomatis*.
- Given its preventable and treatable nature, and its prevalence in many impoverished areas, it was designated as one of the priority diseases under Vision 2020.
Global Response to Emerging Infections Indian Medical PG Question 5: A district reports increasing syphilis cases despite standard interventions. Which program response is most appropriate?
- A. Mass treatment campaign
- B. Enhanced surveillance with targeted outreach and screening (Correct Answer)
- C. Increasing clinic hours only
- D. Public awareness campaign only
Global Response to Emerging Infections Explanation: ***Enhanced surveillance with targeted outreach and screening***
- This approach specifically addresses the rise in cases by actively finding and treating infected individuals and their contacts, which is crucial for **controlling outbreaks** of sexually transmitted infections like **syphilis**.
- **Targeted outreach** ensures high-risk populations are reached, and **enhanced surveillance** allows for better understanding of transmission patterns to guide interventions.
*Mass treatment campaign*
- **Mass treatment** campaigns are generally reserved for diseases with high prevalence and potential for rapid spread in a community, and are typically not the first response for **syphilis**, which often requires individual diagnosis and partner notification.
- While it might reduce prevalence, it doesn't address ongoing transmission dynamics or identify specific **risk factors** at an individual level.
*Increasing clinic hours only*
- While increased clinic access is beneficial, it is a passive approach that does not actively identify cases or reach individuals who may not seek care, especially those who are **asymptomatic** or face barriers to accessing healthcare.
- It might improve access for those already motivated to seek care but won't effectively address an increasing trend in cases by itself.
*Public awareness campaign only*
- A public awareness campaign can improve knowledge but does not directly lead to diagnosis and treatment, which are essential for controlling an active increase in syphilis cases.
- It's a supportive measure but insufficient as a primary response to an **epidemic trend** without accompanying diagnostic and therapeutic services.
Global Response to Emerging Infections Indian Medical PG Question 6: Disease not included under International surveillance
- A. Common cold
- B. Tension headache (Correct Answer)
- C. Rabies
- D. Malaria
- E. Yellow fever

- They are **not communicable** and do not have the potential for widespread international spread.
- This is a **non-infectious neurological symptom** with no epidemic potential.
*Common cold*
- While the **common cold** is highly contagious and caused by various respiratory viruses, it is **not under formal international surveillance**.
- It is generally a mild, self-limiting illness that does not meet the criteria for International Health Regulations (IHR) reporting.
- However, severe acute respiratory syndromes (like SARS or COVID-19) are under international surveillance due to their pandemic potential.
*Rabies*
- **Rabies** is a fatal zoonotic disease included under **WHO International Health Regulations (IHR)** surveillance.
- It requires international monitoring due to high case-fatality rate (nearly 100%) and potential for cross-border transmission through animal movement.
- WHO coordinates global surveillance to track animal reservoirs, implement vaccination programs, and prevent human deaths.
*Malaria*
- **Malaria** is a major disease under **WHO Global Malaria Programme** surveillance with mandatory reporting requirements.
- International surveillance tracks disease burden, drug resistance patterns, vector control effectiveness, and progress toward elimination goals.
- It causes significant morbidity and mortality, particularly in tropical and subtropical regions.
*Yellow fever*
- **Yellow fever** is a mosquito-borne viral hemorrhagic disease explicitly listed under **WHO International Health Regulations (IHR)**.
- Countries must report outbreaks and maintain vaccination requirements for international travel from endemic areas.
- International surveillance prevents epidemic spread and guides vaccination campaigns.

Global Response to Emerging Infections Indian Medical PG Question 10: All are ophthalmological emergencies except -
- A. Endophthalmitis
- B. CRVO (Correct Answer)
- C. Acute congestive glaucoma
- D. CRAO
Global Response to Emerging Infections Explanation: ***CRVO***
- Central Retinal Vein Occlusion (CRVO) is characterized by painless **vision loss** due to retinal hemorrhage and edema, but it is generally *not* considered an immediate, vision-threatening emergency in the same vein as the other options.
- While it requires prompt evaluation and management to preserve vision, CRVO allows for a less urgent intervention compared to conditions that can lead to permanent vision loss within hours.
*Endophthalmitis*
- **Endophthalmitis** is a severe inflammation of the intraocular fluids and tissues, typically caused by infection, and can lead to rapid and irreversible vision loss if not treated urgently.
- It presents with pain, redness, reduced vision, and hypopyon (pus in the anterior chamber), necessitating immediate antibiotic treatment and surgical intervention.
*Acute congestive glaucoma*
- **Acute congestive glaucoma** (acute angle-closure glaucoma) involves a sudden increase in intraocular pressure, causing severe pain, redness, corneal edema, and profound vision loss.
- If left untreated, the high pressure can cause irreversible damage to the optic nerve within hours, making it a true ocular emergency.
*CRAO*
- **Central Retinal Artery Occlusion (CRAO)** is a sudden, painless loss of vision in one eye due to blockage of the central retinal artery, leading to retinal ischemia.
- It is an ocular emergency because irreversible retinal damage and vision loss can occur within 90-120 minutes of the occlusion, requiring immediate intervention to restore blood flow.
