Family and Community Health and Hygiene
Family and Community Health and Hygiene
This domain tests how well you connect personal health practices with community-level sanitation. Expect questions on the WHO definition of health, communicable disease control, safe water, waste disposal, immunization and school health.
Core rules and concepts
- Health is a state of complete physical, mental and social well-being, not merely absence of disease (WHO, 1948).
- Hygiene is personal; sanitation is environmental. Both interrupt the chain of infection: causative agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host.
- Handwashing with soap has six steps and must last at least 20 seconds; it removes transient flora.
- Safe water: boiling for 10–15 minutes, chlorine tablets, or filtration. Storage must be covered and ladled, not dipped.
- Waste segregation: biodegradable, recyclable, hazardous. Composting is aerobic; a soak pit handles grey water.
- ORS is given for dehydration, not to stop stools. Zinc is added for 14 days in childhood diarrhoea.
Worked example
A village reports 20 diarrhoea cases in a week. A student suggests stopping drinking water. Reasoning: diarrhoea causes dehydration; withholding water worsens it. Correct advice is continued fluids, ORS after each loose stool, zinc, safe water, and investigation of the common source such as a well, hand pump or food stall. The chain is broken at transmission and susceptible host.
Traps that cost marks
Confusing disinfection with sterilization; saying ORS stops diarrhoea; discarding colostrum; listing only personal hygiene when the question asks community hygiene.
