Explanation:

• Question 54: A nosocomial infection is defined as an infection acquired in a hospital. An infection transmitted by a vector is a vector - borne infection. A congenital infection is one acquired before or during birth. A chronic infection is one that persists over a long period.
• Question 55: John Snow is famous for his work in identifying the source of the cholera outbreak in London. He used mapping techniques to show the connection between contaminated water (Broad Street pump) and cholera cases. Plague is often associated with flea - borne transmission (e.g., Black Death). Smallpox was eradicated through vaccination efforts. Typhoid is caused by Salmonella typhi and has different epidemiological characteristics than the cholera outbreak Snow investigated.
