Description of the first case of SARS-CoV-2 reinfection in Galicia (Spain)

ABSTRACT

This study presents the first confirmed case of SARS-CoV-2 reinfection in Galicia, Spain, and a summary of the data on the first reinfections studied in the autonomous community. The first patient with a confirmed reinfection, aged 69, started clinical COVID-19 on 28/03/2020 with coughing and asthenia and oxygen saturation of 97%-98%.98%. He then complained of persistent weariness for several months. The clinical episode occurred while in quarantine on 03 March 2022 due to intimate interaction with her cohabitating daughter and a positive COVID-19 (secondary attack rate of 33%). The first positive result was achieved on 03 March 2020 (E gene CT<30, RdRP/S gene CT<30, N gene CT<30). Noserological study was done, and the patient was discharged on 04 March 2020 according to epidemiological guidelines. On 9 January 2021 he presented a second COVID-19 case after 289 days. In this second episode, the patient developed cough and general malaise on 09/01/2021 and was PCR positive on the same day (E gene CT<30, RdRP genes <30%). In both cases, the patient progressed well and did not require hospitalization. Between 1 April 2021, and 10 March 2021, there were 485 re-infections recorded in the Autonomous Community of Galicia, with 245 occurring in the province of A Corua (51%), 68 in Lugo (14%), 37 in Ourense (8%) and 135 in Pontevedra (28%). Because reinfection features and patterns may change, information must be collected throughout the pandemic.
