Nosocomial outbreaks are costly and difficult to manage.

Containment costs escalate with outbreak size.Ward closures, contact tracing and diagnostics can cost hundreds of thousands per outbreak.12 A single CPE outbreak affecting five London hospitals cost €1.1 million (€0.9–1.4 million) over 10 months.3Typical hospital outbreak112 patients infected (3–37)45 days to contain (16–86)€172K containment cost (€11K–€357K)$50K treatment per case ($31K–$74K)4$105K/year ($24K–$214K) for clinical surveillance software without transmission reconstruction5

Outbreak data are fragmented. The response cannot be.

Outbreak investigation remains largely manual.Teams piece together contact tracing, clinical records and microbiology results through ad hoc analyses. The process is slow, labour-intensive, inconsistent and difficult to audit.Nosotrack fuses these data into a unified Bayesian inference engine powered by the open-source, peer-reviewed outbreaker2 model12 to identify transmission chains in near real time, revealing the drivers of disease transmission and enabling targeted control strategies.

Every outbreak leaves a trail. Nosotrack finds it.

Nosotrack reconstructs the transmission tree.Identifying the sources of infection and how disease spreads is critical to devising targeted control strategies.Nosotrack provides a consistent visual interface to the outbreaker2 engine identifying the most likely index case, imported cases, superspreaders, undetected cases, transmission patterns and individuals at risk. Additional developments will help identify potential sources of contamination, such as medical equipment.
