Contact tracing apps unlikely to contain COVID-19 spread

Contract tracing apps used to reduce the spread of COVID-19 are unlikely to be effective without proper uptake and support from concurrent control measures, finds a new study by UCL researchers. The systematic review*, published in Lancet Digital Health, shows that large-scale manual contact tracing alongside other public health control measures – such as physical distancing and closure of indoor spaces such as pubs – is likely to be required in conjunction with automated approaches.
