Apresentação/Introdução
The persistence of COVID-19 related symptoms after the acute infection has been extensively documented. This condition decreases the quality of life and leads to societal and health services burden. The reported incidence varies between 25 and 60% of COVID-19 survivors, including children, depending on follow-up duration and case definition.
Objetivos
We aimed to estimate the sex and age incidence proportion of post-COVID-19 condition in a large cohort of in- and outpatients recruited during the first two epidemic waves and living in the Northern Region of Portugal.
Metodologia
From March to December 2020, 7539 consecutive patients (57.6% women) with SARS-CoV-2 infection, were diagnosed at the largest University Hospital in the North of Portugal. Of those, 1727 (22.9%) were treated as inpatients and 5815 (77.1%) as outpatients. There were 370 (4.9%) in-hospital deaths, and 90 (1.2%) additional deaths identified during follow-up; 1796 patients (23.8%) were unreachable by telephone. Of the 5283 contacted, 3481 (65.9%) accepted to complete a structured computer-assisted telephone questionnaire by trained researchers. The post-COVID-19 condition was defined as symptomatic at presentation with no complete resolution of symptoms 90 or more days after diagnosis.
Resultados
Overall, 2966 (85.2%) of those with SARS-CoV-2 infection were symptomatic at diagnosis. Among them, the incidence proportion of post-COVID-19 condition was 37.4%. It was higher in females (43.5%) than in males (28.5%). The higher incidence among females was consistent across all age strata, except for those younger than 20 and those 70 or older among whom no sex differences were found.
Conclusões/Considerações
More than one-third of the symptomatic COVID-19 cases reported at least one symptom three months after diagnosis. The incidence of post-COVID-19 condition was higher among females of all ages except the youngest (<20 years) and the oldest (≥70 years). This might be due to misattribution of post-COVID-19 symptoms to other illnesses, or low symptom reporting among older women.
