PSM · National programmes: HIV sentinel surveillance
Sample itemA programme manager needs a proxy for the trend of HIV prevalence in the general population of India. Which sentinel group is used by the national HIV sentinel surveillance for this purpose?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Pregnant women attending antenatal clinics
In India's HIV sentinel surveillance, women attending antenatal clinics are the proxy for the general population, while STI clinic attendees, female sex workers, men who have sex with men and injecting drug users represent high-risk groups. Their trend informs the national estimates.
Option by option
A. Pregnant women attending antenatal clinics (correct)
Correct. Antenatal clinic attendees are used as a proxy for the general population.
B. People who inject drugs
People who inject drugs are a high-risk group and do not represent the general population.
C. Attendees of sexually transmitted infection clinics
STI clinic attendees are a high-risk group and give higher prevalence.
D. Female sex workers
Female sex workers are a high-risk group and do not represent the general population.
