Infectious diseases are on the rise.

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.

Nosocomial outbreaks are deadly, costly and difficult to manage.

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.

1 in 10

patients develop an HAI

A WHO global estimate that has not improved in over 15 years.

136M

antibiotic-resistant HAIs / year

HAIs are a major driver of the antimicrobial resistance (AMR) crisis, one of the WHO's top global health threat.

3.5M

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.

Outbreak forensics, end to end.

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

Pathogen agnostic, ready for Disease X.

Nosotrack reconstructs transmission chains in near real-time by integrating epidemiological, genomic and contact data within a unified Bayesian inference framework. The platform 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.

Peer-reviewed science, adopted globally.

Built on over a decade of peer-reviewed methodological research by our team and collaborators. Its inference engine is grounded in scientifically validated methods that have become part of the standard toolkit for outbreak response worldwide.

These methods have supported real investigations by hospitals, research institutions and public health agencies, including SARS-CoV-2 nosocomial outbreaks in Switzerland and the UK, MRSA transmission in UK neonatal intensive care units, Klebsiella pneumoniae in a Nepali neonatal unit, Acinetobacter baumannii in hospitals in North Carolina, and Ebola in the Democratic Republic of the Congo.

Next steps.

We are seeking collaborators and funding to validate and deploy Nosotrack in two stages.

Phase 1

Simulation Study

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.

Phase 2

Pilot Study

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.
