Cholera Course

Lesson 1 • Historical Pandemics and Global Spread

Traces seven cholera pandemics and their geographic spread. Contextualises current outbreaks within a long history of global disease emergence.

Lesson 2 • Vulnerable Populations and Risk Factors

Identifies demographic and socioeconomic factors that increase cholera risk. Grounds later prevention strategies in evidence-based risk stratification.

Lesson 3 • Global Burden and Epidemiology

Quantifies cholera's morbidity, mortality, and economic impact worldwide. Links burden data to priority-setting in public health responses.

Lesson 1 • Pathophysiology of Cholera

Explains intestinal colonisation, toxin binding, and secretory diarrhoea mechanisms. Directly informs fluid replacement volumes and clinical management decisions.

Lesson 2 • Dehydration Assessment and Classification

Teaches systematic dehydration grading using clinical signs. Enables rapid triage decisions that determine the appropriate rehydration protocol.

Lesson 3 • Transmission Routes and Reservoirs

Describes waterborne, foodborne, and environmental transmission pathways. Establishes the ecological context needed to design effective interruption strategies.

Lesson 4 • Complications and Differential Diagnosis

Identifies metabolic, renal, and cardiac complications of severe cholera. Distinguishes cholera from other acute watery diarrhoea causes to prevent misdiagnosis.

Lesson 1 • Culture and Biochemical Identification

Explains selective media, colony morphology, and biochemical confirmation steps. Provides the gold-standard method for definitive species and serogroup identification.

Lesson 2 • Specimen Collection and Transport

Details rectal swab, stool, and water sample collection procedures. Correct technique prevents false negatives and ensures valid laboratory results.

Lesson 3 • Molecular and Serological Methods

Introduces PCR, whole-genome sequencing, and serology for advanced characterisation. Links molecular data to outbreak source tracing and antimicrobial resistance profiling.

Lesson 4 • Rapid Diagnostic Tests

Covers lateral flow RDT principles, performance metrics, and field use. Positions RDTs as first-line tools for outbreak confirmation in resource-limited settings.

Lesson 1 • Antibiotic Therapy and Stewardship

Identifies indications, drug choices, and dosing for adjunct antibiotic use. Emphasises stewardship to preserve efficacy amid rising antimicrobial resistance.

Lesson 2 • Intravenous Fluid Resuscitation

Covers IV fluid selection, rapid infusion rates, and transition to oral therapy. Targets severe dehydration cases where oral intake is insufficient or impossible.

Lesson 3 • Oral Rehydration Therapy Principles

Explains ORS composition, sodium-glucose cotransport, and administration technique. ORT is the cornerstone intervention reducing cholera mortality in all settings.

Lesson 4 • Cholera Treatment Unit Setup

Describes physical layout, triage zones, and infection control for a cholera treatment unit. Operational design directly reduces nosocomial transmission and improves patient flow.

Lesson 1 • Outbreak Threshold and Verification

Defines alert and action thresholds and outbreak verification criteria. Prevents both delayed responses and unnecessary alarm from sporadic cases.

Lesson 2 • Data Management and Visualization

Covers data entry, cleaning, and dashboard creation for outbreak monitoring. Accurate visualization supports decision-making by response teams and health authorities.

Lesson 3 • International Reporting Obligations

Explains mandatory notification under international health regulations and WHO reporting. Ensures compliance with global disease reporting standards to enable coordinated response.

Lesson 4 • Epidemiological Investigation Methods

Teaches line listing, attack rate calculation, and epidemic curve construction. These tools identify the source, mode, and extent of an ongoing outbreak.

Lesson 1 • Safe Water Supply and Treatment

Covers piped water safety, household treatment options, and water quality monitoring. Safe water is the single most impactful structural intervention against cholera.

Lesson 2 • Hygiene Promotion Programmes

Designs handwashing campaigns, food safety education, and behaviour change communication. Sustained hygiene behaviour reduces transmission independent of infrastructure improvements.

Lesson 3 • Sanitation Infrastructure and Fecal Management

Addresses latrine coverage, open defecation elimination, and faecal sludge management. Sanitation improvements break the faecal-oral transmission cycle at the community level.

Lesson 4 • Oral Cholera Vaccine Programmes

Covers OCV types, immunisation schedules, and integration into national programmes. Vaccination provides population-level protection while structural improvements are scaled up.

Lesson 1 • Rapid Response Team Activation

Describes team composition, deployment triggers, and initial assessment protocols. Rapid mobilisation within 24–48 hours is critical to containing early outbreak spread.

Lesson 2 • Risk Communication and Community Engagement

Teaches message development, rumour management, and community mobilisation strategies. Effective communication increases care-seeking behaviour and reduces transmission.

Lesson 3 • Response Monitoring and Evaluation

Defines key performance indicators and after-action review processes for outbreak response. Systematic evaluation improves future preparedness and accountability.

Lesson 4 • WASH Interventions in Outbreaks

Covers emergency water treatment, sanitation, and hygiene promotion during outbreaks. WASH interventions address the root transmission pathways driving case counts.

Lesson 1 • Minimum Standards in Emergencies

Applies humanitarian minimum standards for water, sanitation, and health in cholera response. Standards provide benchmarks for quality and accountability in resource-scarce settings.

Lesson 2 • Supply Chain and Logistics Management

Covers procurement, pre-positioning, and last-mile delivery of cholera supplies. Reliable supply chains prevent treatment gaps that increase case fatality rates.

Lesson 3 • Transition from Emergency to Recovery

Guides the shift from acute response to sustainable WASH and health system recovery. Transition planning prevents resurgence when emergency resources are withdrawn.

Lesson 4 • Coordination in Humanitarian Response

Describes cluster system roles, inter-agency coordination, and information sharing. Effective coordination prevents duplication and fills critical gaps in outbreak response.
