2. What kind of disease is Crohn’s disease that was recently seen in news?
[A] A respiratory disorder
[B] Autoimmune neurological disorder
[C] A heart disease
[D] A chronic inflammatory bowel disease
Show Answer
Correct Answer: D [A chronic inflammatory bowel disease ]
Notes:
Recent research shows that eating diets high in Ultra Processed Foods (UPFs) can worsen gut inflammation and increase Crohn’s disease flare-ups. Crohn’s Disease is a chronic Inflammatory Bowel Disease (IBD) that causes swelling and irritation in the digestive tract. It usually affects the small intestine and the beginning of the large intestine. Inflammation can spread deep into the bowel layers, causing pain and serious complications. Common symptoms include diarrhea, abdominal cramps, and weight loss. It mostly develops between ages 20 and 29. The exact cause is unknown but may involve genes, immune reactions, and the microbiome. There is no cure, but treatment helps control symptoms and maintain remission.

5. Which country has become the eighth country in the world to introduce the Typhoid Conjugate Vaccine (TCV) into its immunisation programme?
[A] Sri Lanka
[B] Myanmar
[C] Bangladesh
[D] Nepal
Show Answer
Correct Answer: C [Bangladesh]
Notes:
Bangladesh became the 8th country in the world to introduce the Typhoid Conjugate Vaccine (TCV) in its routine immunisation programme. Around 50 million children aged 9 months to 15 years will receive the vaccine under a nationwide campaign. India is the major vaccine supplier for this drive but has not yet included TCV in its Universal Immunisation Programme (UIP). Typhoid fever is caused by the Salmonella typhi bacterium and spreads through contaminated food and water or vectors like flies. The disease can lead to fever lasting several weeks, and complications like intestinal perforation can cause death. The World Health Organization (WHO) estimates 9–12 million global typhoid cases and over 1 lakh deaths annually — with India, Bangladesh, and Pakistan as hotspots
