Characteristics of endemic human coronavirus infections during times of COVID-19 pandemic.

Introduction: After the implementation of mitigation strategies during the COVID-19 pandemic, the incidence of respiratory viruses, including human coronaviruses (HCoV), experienced a significant decrease. The aim of this study is to characterize the epidemiology and clinical aspects of HCoV infections in ambulatory adults during COVID-19 pandemic times.

Methods: descriptive, prospective, longitudinal study performed in a private hospital in La Plata, Buenos Aires, Argentina between November 2020 and October 2022; 458 outpatient adults with upper respiratory tract infections (URTI) were studied undergoing clinical and microbiological follow-up.

[Impact of population mobility on the behavior of respiratory viruses during the COVID-19 pandemic].

Introduction: During the SARS-CoV-2 pandemic, Argentina population suffered from significant changes in population mobility due to non-pharmaceutical interventions. The aim of this study was to describe the impact of the mobility restrictions to the rates of positivity and diversity among different respiratory viruses.

Methods: Retrospective analytical study performed at Instituto Médico Platense in La Plata that included 458 patients with nasopharyngeal swab to search for respiratory pathogens by multiplex PCR.
