Every outbreak is different. Effective control requires rapidly identifying the specific drivers of transmission: who infected whom, who the superspreaders are, which cases are undetected or imported, where and how transmission occurred, and who is most at risk.
Healthcare facilities are among the highest-risk environments for infectious disease transmission, bringing together vulnerable populations, frequent close contact, and diverse pathogens. Healthcare-associated infections (HAIs) remain among the most common adverse events in healthcare delivery.
antibiotic-resistant HAIs / year
HAIs are a major driver of the antimicrobial resistance (AMR) crisis, one of the WHO's top global health threat.
annual deaths
The WHO's projected mortality from HAIs unless infection-prevention investment scales meaningfully in the next decade.
AMR's most underrated driver
Hospital outbreaks are the breeding ground for resistant strains. Stopping them earlier is the cheapest and most efficient solution.
Current outbreak surveillance tools work in silos. Nosotrack fuses their data streams into a unified analytical engine.
Nosotrack infers who-infected-whom in real-time, enabling infection prevention and control teams to identify how infections spread and design targeted interventions before outbreaks escalate
Nosotrack reconstructs transmission chains in near real-time by integrating epidemiological, genomic and contact data using the open-source Bayesian inference framework outbreaker2. It identifies the likely source of each infection and quantifies the uncertainty around it.
Designed to work across pathogens, healthcare settings and outbreak scenarios, Nosotrack enables response teams to understand how outbreaks spread, and determine when and where to intervene.
Built on over a decade of published methodological research by our team and peers. Its inference engine (outbreaker2) is grounded in scientifically validated methods that have become part of the standard toolkit for outbreak response worldwide.
These methods have supported real-world outbreak investigations by hospitals, research institutions and public health agencies, including SARS-CoV-2 nosocomial outbreaks in Switzerland and the UK, Klebsiella pneumoniae in a Nepali neonatal unit, vancomycin-resistant Enterococcus faecium in an Australian tertiary hospital, multidrug-resistant Acinetobacter baumannii at a burn centre in North Carolina, and Ebola in Guinea.

Nosotrack is currently at the prototype stage.
A dashboard, live at nosotrack.onrender.com, demonstrates the core outbreak-reconstruction engine (outbreaker2) with an integrated LLM interface. Additional modules, including contaminated-source (e.g. medical device) identification and an intervention simulator, are under development.
Conduct simulation studies under realistic operational constraints to determine the conditions under which Nosotrack improves outbreak control.
This phase will assess Nosotrack's effectiveness across pathogens, hospital settings, and levels of data availability.
Deploy the platform in real-time in a hospital environment.
This phase will generate real-world evidence on reduced infections, cost savings, and improved hospital capacity management.
