Hepatitis A is a viral liver infection that spreads through contaminated food and water. While usually mild in children, it can be severe in older children and adults, sometimes leading to liver failure. Improved sanitation has reduced early childhood exposure, leaving many young people vulnerable. Safe and effective vaccines are available, including a single-dose option with long-lasting protection. Despite this, Hepatitis A is not yet part of India’s national immunisation program. Strengthening surveillance, promoting hygiene, improving water quality, and introducing phased vaccination can help prevent outbreaks and protect public health.

These cells work through molecules PU.1 and CD28, offering a potential new direction for treatment. Alzheimer’s, a progressive brain disorder causing memory and cognitive decline, is a growing public health challenge globally and in India. Governments are responding with awareness campaigns, healthcare policies, and research initiatives, but challenges like high costs, limited access, and early diagnosis remain. The discovery highlights the promise of combining scientific research, healthcare, and policy to combat Alzheimer’s disease.
