1. Primary Health Centre (PHC)
Introduction/Concept:
The concept of PHC was given by the Bhore Committee in 1946 - envisioned as a basic health unit to provide integrated curative and preventive health care to the rural population, with emphasis on preventive and promotive aspects. The Central Council of Health (1953) recommended establishment of PHCs in community development blocks.
Population Coverage:
- 1 PHC for every 30,000 rural population in plains
- 1 PHC for every 20,000 population in hilly, tribal, and backward areas
- As of March 2017: 25,650 PHCs established across India
- Each PHC is supported by 6 sub-centres
Types of PHC (IPHS 2012):
- Type A PHC: Less than 20 deliveries per month
- Type B PHC: 20 or more deliveries per month
Functions of PHC (10 Essential Elements - Alma-Ata based):

2. ASHA (Accredited Social Health Activist)
Introduction:
ASHA was introduced under the National Rural Health Mission (NRHM), launched in 2005. She is the first point of contact for health care between the community and the health system. As of 2018, approximately 9.15 lakh ASHAs have been selected across India.

3. Anganwadi / Anganwadi Worker (AWW)
Introduction:
The Anganwadi (meaning "courtyard shelter") is the centre of the Integrated Child Development Services (ICDS) scheme, launched in 1975 by the Government of India. It is the world's largest early childhood development programme. The Anganwadi Worker (AWW) is a community-based frontline worker who runs the Anganwadi Centre (AWC).

Anganwadi Helper (AWH): An assistant to the AWW who helps in cooking, cleaning, and child care activities.
Link to MCH: AWC is the focal point for VHSND - where ANM provides immunization and ANC, and ASHA brings beneficiaries. The AWW is a critical link in the ASHA-ANM-AWW triad for community health.
Significance: AWCs serve as the front-line delivery points for child nutrition, early childhood development, and maternal health - directly contributing to the reduction of IMR, MMR, and child malnutrition.

5. Health Care Worker / Community Health Worker (CHW)
Introduction:
Health care workers are individuals engaged in actions whose primary intent is to enhance health. Community Health Workers (CHWs) are broadly defined as health workers who are members of the community they serve and are trained to provide basic health care, health education, and referral services. In the Indian context, the term encompasses a wide range of personnel from village-level volunteers to trained professional staff.
WHO Definition: A health care worker is a person who delivers personal health services or has an impact on the health of the population.
Categories of Health Care Workers in India:
| Category | Examples |
|---|
| Voluntary/Community-level | ASHA, Village Health Guide, Traditional Birth Attendant (Dai) |
| Paramedical/Frontline | ANM, MPW (Male), Anganwadi Worker |
| Supervisory | LHV/Health Assistant Female, Health Assistant Male |
| Facility-based (PHC level) | Medical Officer, Staff Nurse, Pharmacist, Lab Technician |
| CHC/Hospital level | Specialist Doctors, Nurses, Radiographers, Physiotherapists |
Role of Community Health Workers:
- Promotive: Health education, behaviour change communication, hygiene promotion, nutrition counselling
- Preventive: Immunization, disease surveillance, vector control, maternal care
- Curative: First aid, treatment of minor ailments, DOTS provision, distribution of ORS/medicines
- Rehabilitative: Follow-up of patients, referral linkages, support for disabled persons
Characteristics of an effective CHW:
- Resident of and accountable to the community
- Selected by the community (or with community participation)
- Trained in basic health skills
- Supervised and supported by the formal health system
- Linked with the referral network
ASHA as India's Model CHW:
- Introduced under NRHM 2005
- ~9.15 lakh ASHAs nationwide
- Incentive-based, community-selected, village-resident
- Connects household to PHC and hospital
Key Principles for CHW Programmes (WHO):
- Community ownership and participation
- Appropriate training and supervision
- Adequate and timely remuneration/incentive
- Integration with the formal health system
- Continuous capacity-building
Significance:
Health care workers, especially community-based workers, are indispensable for achieving Universal Health Coverage (UHC). They bridge the gap between hard-to-reach communities and the formal health system, and are essential for the "last mile delivery" of health services - especially for MCH, immunization, disease control, and health promotion goals.
