CM8.1 | CM8.1 | Communicable Disease Control at Primary Care — Summary & Reflection

KEY TAKEAWAYS

India's communicable disease burden — led by tuberculosis, malaria, dengue, leprosy, HIV, and diarrhoeal/respiratory infections — converges on the primary health centre as the critical first-contact point. The epidemiological triad (agent, host, environment) explains every disease's transmission pattern and guides the selection of control measures. PHC-level control spans primary prevention (UIP immunisation, sanitation, vector control), secondary prevention (early detection using sputum smear/CBNAAT for TB, RDT for malaria, NS1 antigen for dengue; treatment; isolation; contact tracing), and tertiary prevention (disability limitation). National programmes — NTEP (TB elimination, NIKSHAY), NVBDCP (vector-borne diseases), NLEP (MDT leprosy), NACO (HIV) — provide the operational framework. The IDSP surveillance system, operating through S/P/L forms from community to national level, enables outbreak detection and rapid response. The primary care physician anchors this entire system by early diagnosis, compulsory notification, treatment initiation, contact tracing, community education, and timely referral.

REFLECT

Consider the case that opened this module. The medical officer recognised a probable TB case. Beyond ordering a sputum test, what three immediate public health actions should she take in the next two hours? Which of those actions requires notification on NIKSHAY, and what information is needed to complete that entry? How would her approach differ if two more coughing patients from the same village presented the same week — would that trigger an IDSP alert, and at which form level?
