Which disease is described as highly infectious and infects the liver?

• A. Human Hepatitis B
• B. Human Immunodeficiency Virus
• C. Influenza
• D. Malaria

Answer: (A)

Think about infections that specifically target the liver and are known for being highly contagious. Hepatitis B fits this description: the virus is highly infectious and it attacks liver cells, causing hepatitis that can be acute or chronic and potentially lead to serious liver damage. It spreads through blood and bodily fluids, which makes it a major concern in any setting where there could be blood exposure. Vaccination is available and standard precautions are essential in environments like salons to prevent transmission.

The other options don’t match the combination of being both highly infectious and liver-infecting. HIV mainly harms the immune system, not the liver. Influenza targets the respiratory system. Malaria is a parasitic disease transmitted by mosquitoes and, while the parasite has a liver stage, malaria is not described primarily as a liver-infecting disease.
