Abstract
Background
SARS-CoV-2 infection affects health, well-being, and the economy, especially considering the persistence of symptoms following an acute episode. This study aims to (1) estimate the frequency of symptoms following SARS-CoV-2 infections, (2) characterize symptoms compatible with post-COVID-19 conditions, and (3) explore risk factors for persistent symptoms among individuals from two Chilean cities diagnosed with COVID-19 at least once.
Methods
This cross-sectional exploratory study involved a convenience sample of individuals who participated in a prior seroprevalence study in Chile. Participants were recruited by phone between November 2023 and January 2024, and self-reported persistent COVID-19 symptoms using the modified Yorkshire Rehabilitation Scale, which assessed symptom severity and functional disability across three dimensions. Bivariate analysis explores the association between sociodemographic and health variables and reported symptoms using the Mann-Whitney-Wilcoxon and Kruskal-Wallis tests. Two Negative binomial models (Model 1: clinical factors and Model 2: clinical plus sociodemographic factors) evaluated factors associated with the severity of post-COVID-19 symptoms.
Results
Of the 144 participants successfully contacted, 83 met the inclusion criteria. A total of 80.7 % reported symptoms consistent with post-COVID-19. The most frequently reported symptoms were sleep disturbances (59.7 %), anxiety (59.7 %), and memory problems (58.2 %). Only three participants had received a formal post-COVID diagnosis, and none were receiving care through Chile’s universal post-COVID program. Symptom severity was significantly higher in women (p = 0.04), individuals with two or more COVID-19 episodes (p = 0.04), and those with comorbidities (p = 0.02). Negative binomial regression analysis indicated that multiple COVID-19 episodes were associated with greater symptom severity.
Conclusions
A high percentage of participants experienced post-COVID-19 symptoms. Despite the high symptom burden, access to formal diagnosis and care was minimal, highlighting the need to strengthen diagnostic and management protocols within the Chilean healthcare system.
期刊介绍:
The Journal of Infection and Public Health, first official journal of the Saudi Arabian Ministry of National Guard Health Affairs, King Saud Bin Abdulaziz University for Health Sciences and the Saudi Association for Public Health, aims to be the foremost scientific, peer-reviewed journal encompassing infection prevention and control, microbiology, infectious diseases, public health and the application of healthcare epidemiology to the evaluation of health outcomes. The point of view of the journal is that infection and public health are closely intertwined and that advances in one area will have positive consequences on the other.
The journal will be useful to all health professionals who are partners in the management of patients with communicable diseases, keeping them up to date. The journal is proud to have an international and diverse editorial board that will assist and facilitate the publication of articles that reflect a global view on infection control and public health, as well as emphasizing our focus on supporting the needs of public health practitioners.
It is our aim to improve healthcare by reducing risk of infection and related adverse outcomes by critical review, selection, and dissemination of new and relevant information in the field of infection control, public health and infectious diseases in all healthcare settings and the community.
