OBJECTIVES: To know the impact of COVID-19 in incidence and lethality in nursing homes in Galicia. METHODS: This is a descriptive study of nursing homes residents and workers with confirmed COVID-19. The analysis spanned from March 1, 2020 to March 27, 2022, stratified into 6 periods (one per wave). The impact on incidence (attack rate, number of outbreaks, reinfections, sex, age, and diagnostic technique) and lethality (by sex, age, place of death, and number of centers with deaths) was analyzed. RESULTS: There were 15,819 people affected, 51.9% of the jobs and 47.0% of the workers. The attack rate in residents was: 5.8% in the first wave, 10.4% in the second, 6.3% in the third, 0.1% in the fourth, 2.1% in the fifth and 27.3% in the sixth. In the sixth wave, there were 11.3% reinfections and the number of outbreaks in was 3 times higher than in the second. The case fatality in residents was higher during the first wave (21.8%) and lower during the sixth (2.4%). He only had one worker in relation to COVID-19. CONCLUSIONS: Surveillance of COVID-19 in nursing homes was essential to understand the dynamics of the disease. The sixth wave was the one with the highest incidence and the lowest lethality. Lethality was higher in the first wave. The fourth and fifth waves had a lower incidence due to the effects of vaccination.
