Qualitative analysis of cholera outbreaks: Malawi 2022–24

The Malawi qualitative study shows that cholera became a prolonged epidemic when climate shocks, health‑system breakdowns, and social vulnerabilities converged, not from a single cause. Use interaction-focused coding, preserve temporality, and translate frontline testimony into operational recommendations for sustained, multisectoral response.

• Cholera drivers: three converging pathways were climate shocks, health‑system breakdowns, and social/economic determinants, according to the PLOS qualitative assessment.
• Scale and impact: the Ministry of Health data cited in the study report 57, 639 cases and 1, 727 deaths across Malawi during 2022–2024.
• Methodological implication: code for interactions and temporality to expose feedback loops that single‑sector fixes cannot address.

The Malawi study shows that repeated climate shocks, damaged infrastructure, and social coping strategies combined to turn a seasonal spike into a multi‑year epidemic. The PLOS qualitative assessment (published 10 July 2026) used 24 semi‑structured interviews and field observations from Neno and Chikwawa Districts (data collected Aug–Sep 2024) to map how climate events and structural vulnerabilities expanded transmission and stretched response capacity.

• Three converging pathways identified: climate shocks, health‑system breakdowns, and social/economic determinants.
• Reported burden: 57, 639 cases and 1, 727 deaths across Malawi, cited from the Malawi Ministry of Health in the study.
• Operational implication: single‑sector fixes like temporary WASH supplies will not stop outbreaks when pathways converge, requiring sustained, cross‑sectoral planning.

The study answers how the outbreak became an epidemic by framing it as a system failure driven by intersecting factors rather than a single cause. Repeated cyclones caused infrastructure damage and mass displacement, which degraded WASH and stretched health services, damaged roads and bridges interrupted medical and WASH supply chains, poverty and cross‑border movement amplified transmission, and a new, more contagious Vibrio cholerae strain further accelerated spread.

• Temporal compression: short recovery windows after successive disasters prevented rebuilding and preparedness.
• Health‑system unpredictability: unseasonal outbreaks challenged planning and resource allocation.
• Social coping strategies, including shared water sources and crowded IDP camps, increased exposure.

Follow these ten steps to reproduce the Malawi study workflow: 1) Gather interviews, field notes, and facility reports, and tag dates and locations. 2) Upload audio and transcripts to Evidano and apply a custom dictionary for local terms. 3) Run initial auto‑coding and review the suggested codebook. 4) Import or create your codebook and lock high‑confidence codes. 5) Generate theme frequency and co‑occurrence reports (climate, WASH, displacement, system failure). 6) Run cross‑segment comparisons (IDP versus non‑IDP, district A versus B). 7) Extract representative, de‑identified quotes for each theme. 8) Produce visualizations such as co‑occurrence networks and hierarchical code→subcode maps. 9) Draft an operational brief with evidence‑linked recommendations and a timeline. 10) Share an interactive report with stakeholders for rapid decision making.

The Malawi qualitative study (published 10 July 2026) shows that outbreaks become epidemics when climate shocks, weak health systems, and social vulnerabilities collide, and researchers should code for interactions, preserve temporality, and translate frontline testimony into operational levers.
