On 30 January 2020, the WHO declared a Public Health Emergency of International Concern (PHEIC) for the COVID-19 outbreak. On 7 March 2020, there were more than 100,000 confirmed cases in 88 countries. Telemedicine, otherwise known as telehealth, has been used at small scale in past outbreaks, including previous coronavirus outbreaks (SARS; MERS) and other PHEICs (Ebola; Zika). The objective was to describe the global larger scale use and practicality of telehealth in the COVID-19 outbreak. The 2015 conceptual framework of telemedicine during an outbreak for epidemiological assessment and clinical management (Ohannessian R.) was used to describe the use cases. A multi-country analysis from China, France, USA and UK was performed with a literature review using official institution websites, grey literature, media/business reports, as scientific articles were not yet published. Video and chat consultations were used for symptomatic patient assessments through private telehealth providers in all countries. In the USA, the Telehealth Services During Certain Emergency Periods Act of 2020 was voted by the Congress on 4 March 2020 to suspend restrictive rules of Medicare funding for telehealth home consultations. Triage via online auto-questionnaires were created by private providers and public authorities. In the UK, from 26 February to 2 March, 70,000 enquiries were made to a dedicated NHS111 online service. In China, teleradiology networks were also used for diagnostic of COVID-19 cases. Video consultation was used in France to monitor home isolated patients and non COVID-19 patients, to avoid risks of exposure. Telehealth has been useful to the COVID-19 outbreak but efforts to better describe cases and evaluate impact on the public health response should be promoted. National and international health authorities should be aware of the opportunities offered by telehealth during outbreaks, and may consider its integration in public health emergencies preparedness plans. KEY MESSAGES: Telehealth was useful for the public health response to COVID19 outbreak. Telehealth should be integrated into public health preparedness plans.
