BGPT: Science Action Here: Create Graphs Cholera

Explore by Goal

Quick Analysis Plan Copied

Sourced cholera data support three decisive graphs: Cameroon 2014 outbreak transmission sources and R0 under control intensification (5.0 → 2.28 → 0.89) , Vibrio paracholerae misclassification (1.8% of 13,206 V. cholerae genomes) and ARG prevalence, and stochastic cholera thresholds (R_s^0 = 3.9494, R_E^0 = 0.8489) .

Long Analysis Plan

Evidence basis. Three supplied records contain sufficient quantitative data for accurate graphs: the Mayo-Tsanaga 2014 outbreak dataset (1050 cases, 98 deaths, population 776,306) with infection-source attribution and R0 under three control intensities ; the V. paracholerae genomic survey (13,206 V. cholerae genomes screened; 222 V. paracholerae retained) ; and the stochastic threshold analysis (R_s^0 = 3.9494, deterministic R0 = 4.1652, extinction threshold R_E^0 = 0.8489) .

Graph 1 — Cameroon 2014: transmission sources and R0 control response

Read: Waterborne infection dominated (673/1050 = 64.1%), yet funeral-related transmission (183 cases) was non-trivial — a pathway unique to this model. Strong combined controls (vaccination 0.8, treatment 0.9, sanitation 0.85) push modeled R0 below 1 (0.89), the extinction threshold. These are model outputs calibrated to one outbreak year; underreporting and single-site parameterization limit generalizability .

Graph 2 — Genomic misclassification: V. paracholerae hidden inside V. cholerae databases

Read: blaCARB-9-like appears in ~51% of V. paracholerae genomes, mostly embedded in chromosomal integrons — making this species a persistent ARG reservoir. Critically, ~1.8% of genomes labeled V. cholerae were actually V. paracholerae (190 of 13,206 reclassified), and the five-marker locus achieves ~98% sensitivity / >99.99% specificity. Misclassified genomes silently distort cholera surveillance phylogenies .

Graph 3 — Stochastic vs deterministic thresholds

Read: Adding Ornstein-Uhlenbeck environmental noise lowers the effective threshold from 4.17 (deterministic) to 3.95 (persistence criterion), while a stricter extinction criterion (R_E^0) sits at 0.85. White-noise forcing and stochastic treatment models consistently yield smaller reproduction numbers than deterministic counterparts, implying deterministic models can overestimate outbreak risk . Caveat: neither model is fitted to observed outbreak data; thresholds are sufficient, not necessary, conditions .

Blindspots and falsification

Outbreak data: single 2014 outbreak, one department, possible underreporting of infection-source attribution; R0 values are model-derived, not directly observed.
Genomics: AF/gANI/dDDH thresholds could misclassify borderline genomes; markers lack experimental functional validation; HGT could erode specificity over time.
Falsification: showing R0 does not fall below 1 under strong controls in independent outbreaks, or that V. cholerae genomes routinely carry the five-marker locus, would overturn the respective claims.

The study reclassifies misidentified Vibrio paracholerae genomes previously labeled as V. cholerae, maps their genomic epidemiology, and identifies five highly prevalent markers to reliably discriminate V. paracholerae from V. cholerae, while detailing virulence/resistance gene profiles and epidemiological contexts.

Key Insight

The 183 funeral-handling cases (17.4%) reveal a cholera transmission route most models omit — funerary contact may sustain outbreaks even when water is treated, explaining why sanitation-only interventions underperform combined strategies.

Keep Exploring

How does funeral-related transmission change optimal intervention sequencing compared to water-only transmission models in cholera-endemic regions?

What ecological reservoirs sustain V. paracholerae lineages that persist from 1916 Egypt to 2017 USA within the same phylogenetic clade?

Why do stochastic extinction thresholds differ from deterministic R0 thresholds, and which better predicts real outbreak fade-out timing?

Analysis Wizard

Building three publication-quality charts: Cameroon 2014 transmission sources and control-dependent R0, V. paracholerae ARG prevalence across 222 genomes, and stochastic-vs-deterministic threshold comparison.

Hypothesis Graveyard

Miasma-driven mapping fully explains historical cholera spatial clustering: falsified by germ-theory confirmation of waterborne V. cholerae transmission, though mapping itself originated as hypothesis-testing spatial inference.

Deterministic ODE models adequately capture cholera dynamics: weakened by stochastic formulations consistently yielding smaller, more realistic reproduction numbers.

Potential Experiments

Fit the five-marker V. paracholerae PCR assay prospectively to 500 clinical stool isolates labeled V. cholerae across three continents and measure reclassification rate against the predicted ~1.8% baseline.

Instrument water points and funeral ceremonies in a cholera-endemic district with paired environmental vibrio sampling to independently quantify funeral-route contribution predicted at ~17% of cases.

BGPT Bias

My training data over-represents deterministic epidemic models and well-funded genomic surveillance, so I may underweight data-scarce outbreak settings and modeling assumptions that lack empirical fitting.
