The 31 pages that link to Contact tracing, each with the reason it gives.

• Public healthRelated: It interrupts transmission chains when combined with testing and isolation.

• EpidemiologyRelated: It uses transmission links to find exposed people and prevent further spread.

• QuarantineRelated: Tracing identifies who may need quarantine after an exposure.

• Incubation periodRelated: Incubation estimates help define which contacts and exposure dates matter.

• Public health surveillanceRelated: Surveillance findings can guide tracing, while tracing generates additional case data.

• ScabiesRelated: Treating close contacts at the same time helps prevent reinfestation and further spread.

• False negativeRelated: An infected person with a false-negative result may be missed as a source of exposure.

• Outbreak investigationRelated: Tracing contacts can reveal transmission links and help interrupt spread.

• Asymptomatic infectionRelated: Tracing can find infections that symptom-based case detection misses.

• Basic reproduction numberRelated: Tracing can interrupt transmission chains and reduce the effective reproduction number.

• EpidemicRelated: It interrupts transmission chains by finding exposed people before they spread infection.

• Bluetooth Low EnergyRelated: Some digital tracing systems used BLE proximity observations to estimate encounters.

• QR codeRelated: QR check-in systems recorded visits to support exposure notification during the COVID-19 pandemic.

• Infectious disease transmissionRelated: Tracing reconstructs potential transmission links so exposed people can test, isolate, or receive care.

• PandemicRelated: It can interrupt transmission chains when cases are found promptly.

• Respiratory transmissionRelated: Exposure histories can reveal contacts sharing air or space during infectious periods.

• COVID-19 lockdownsRelated: Tracing could complement restrictions by finding transmission chains that broad limits could not target.

• Pathogen transmissionRelated: Tracing identifies possible onward transmission links so exposed people can take precautions.

• Mobile healthRelated: Mobile technologies can help record contacts and distribute exposure alerts.

• Pneumonic plagueRelated: Identifying close contacts helps direct monitoring and preventive treatment.

• DiphtheriaRelated: Tracing close contacts helps limit spread and identify people needing prophylaxis or vaccination.

• MpoxRelated: Tracing contacts helps interrupt transmission chains after mpox exposure.

• KikwitRelated: Teams used contact tracing to find exposed people and interrupt chains of transmission.

• Peter PiotRelated: Ebola investigations used contact tracing to map chains of transmission.

• SARS outbreakRelated: Tracing contacts helped public-health teams find exposed people before further spread.

• West African Ebola epidemicRelated: Tracing contacts helped locate transmission chains and interrupt spread.

• COVID-19 pandemic in ParaguayRelated: Tracing supported early containment when Paraguay’s case numbers were still manageable.

• Nipah virus infectionRelated: Tracing Nipah contacts helps detect secondary cases and guide isolation.

• Wu Lien-tehRelated: Tracking cases and contacts supported the epidemic’s containment measures.
