Euro Surveill. 2020 Jun;25(23):2000972. doi: 10.2807/1560-7917.ES.2020.25.23.2000972.

Abstract

We report the effectiveness of automated text messaging for active surveillance of asymptomatic close contacts of coronavirus disease (COVID-19) cases in the Cork/Kerry region of Ireland. In the first 7 weeks of the COVID-19 outbreak, 1,336 close contacts received 12,421 automated texts. Overall, 120 contacts (9.0%) reported symptoms which required referral for testing and 35 (2.6%) tested positive for COVID-19. Non-response was high (n = 2,121; 17.1%) and this required substantial clinical and administrative resources for follow-up.

Keywords: COVID-19; Ireland; active surveillance; outbreak control; public health.
