CM8.1-7 | Disease Epidemiology and Control — Assignment

CLINICAL SCENARIO

You are the newly posted medical officer of a PHC serving a population of 25,000 in a semi-urban district of central India. During the post-monsoon season, you receive notification of a cluster of fever-with-thrombocytopenia cases from three villages in your catchment area. Simultaneously, your sub-centre ASHA reports two children with painless skin patches and thickened nerves in a remote hamlet. You must respond to both situations while continuing to deliver routine NPCDCS screening and UIP services.

Instructions

Using evidence-based principles from community medicine (Park's textbook, current national programme guidelines, and IDSP protocols), write a structured analytical response to the questions below. Your answers should reflect the role of a PHC medical officer — not a hospital specialist. Cite specific national programme names, current drug regimens, and surveillance forms where relevant. Use current programme names throughout (NTEP, not RNTCP; NVBDCP for vector-borne diseases).

Length: Section A: 600-800 words. Section B: 500-700 words. Section C: 400-600 words. Total: 1,500-2,100 words. Tables and schematic descriptions are encouraged where appropriate; they do not count against the word limit.

What to Submit

Section A — Outbreak Investigation and Response (40 marks)

Section B — National Programme Application (35 marks)

Section C — Community-Level Planning (25 marks)

Grading Rubric — Disease Epidemiology and Control — Assignment Rubric

Criterion	Points	Full-marks descriptor
Outbreak investigation — Accuracy and completeness of 10-step framework application, correct use of IDSP forms (S/P/L), attack rate calculation, epidemic curve interpretation, and identification of case definition (CM8.4)	25 pts	All 5 steps correctly described with right forms/actors; attack rate calculated correctly (4%); epidemic curve distinction (point vs propagated) is precise; case definition cited from IDSP protocol
Surveillance training — Verification of active vs passive zero-reporting, data gap correction, and ASHA training methodology aligned with CM8.6 responsibilities	15 pts	Clearly distinguishes active vs passive zeros; references village health register cross-check; training plan includes demonstration + follow-up verification; avoids punitive framing
National programme protocols — Correct identification of NLEP case definition, MDT regimen (PB vs MB), grade-2 disability prevention; NPCDCS cervical cancer screening (VIA protocol, referral pathway, HPV vaccination target group)	25 pts	NLEP: correct PB (dapsone+rifampicin 6 months) and MB (dapsone+rifampicin+clofazimine 12 months) regimens; correct grade-2 disability prevention (self-care, protective footwear, regular nerve assessment); VIA: correct positive criterion (acetowhite lesion within transformation zone); referral for large lesion correctly stated (district hospital/CHC for cryotherapy/LEEP or biopsy); HPV target correctly stated (girls 9-14 under UIP)
NCD management and intersectoral linkage — Classification of hypertension (Stage 1 = 140-159/90-99) and diabetes (FBG ≥126 mg/dL = diabetes), PHC management protocol, and relevant programme linkages	10 pts	Stage 1 HT correctly classified; diabetes diagnosed correctly from FBG 186 mg/dL (>126); PHC management includes lifestyle counselling + metformin initiation + BP monitoring + NMH programme registration; two relevant programmes correctly identified (e.g. NTEP — high DM-TB co-morbidity risk; NACO — relevant for high-risk occupation)
Community programme planning — SMART objectives, activity planning across NTEP/NVBDCP/NPCDCS, evaluation indicators, and IDSP-triggered adaptive management (CM8.5, CM8.7)	25 pts	Three SMART objectives clearly stated with measurable indicators and timelines; activities mapped to each programme axis with specific PHC roles; evaluation indicators are programme-specific and measurable (e.g. case notification rate for NTEP, API for malaria, diabetes detection rate for NPCDCS); IDSP adaptive management described with threshold for action (e.g. alert threshold on S-form)
