  • An ecological study on reinfection rates using a large dataset of RT-qPCR tests for Sars-CoV-2 in Santiago of Chile

    Open AccessClaudio Acuña‐Castillo, Claudio Acuña-Castillo et al.ARTICLEFrontiers in Public Health2023

    Introduction: As the SARS-CoV-2 continues to evolve, new variants pose a significant threat by potentially overriding the immunity conferred by vaccination and natural infection. This scenario can lead to an upswing in reinfections, amplified baseline epidemic activity, and localized outbreaks. In various global regions, estimates of breakthrough cases associated with the currently circulating viral variants, such as Omicron, have been reported. …

  • Sensitivity analysis of rapid antigen tests for the Omicron Sars-CoV-2 variant detection from nasopharyngeal swab samples collected in Santiago of Chile

    Open AccessCarlos Barrera‐Avalos, Carlos Barrera-Avalos et al.ARTICLEFrontiers in Public Health2022

    The COVID-19 pandemic continues to be a concern and keeps global health authorities on alert. The RT-PCR technique has been the gold-standard assay for detecting the SARS-CoV-2 virus. However, rapid antigen tests (RATs) have been widely used to increase the number of tests faster and more efficiently in the population. Nevertheless, the appearance of new viral variants, with genomic mutations associated with greater contagiousness and immune evas…

  • Evaluation and comparison of the sensitivity of three commercial RT-qPCR kits used for the detection of Sars-CoV-2 in Santiago, Chile

    Open AccessRoberto Luraschi, Álvaro Santibáñez et al.ARTICLEFrontiers in Public Health2022

    Introduction: The COVID-19 pandemic is still in force, causing global public health challenges and threats. Although vaccination and herd immunity have proven to be the most efficient way to control the pandemic, massive and early testing of patients using the RT-qPCR technique is crucial for constant genomic surveillance. The appearance of variants of SARS-CoV-2 with new mutations can reduce the efficiency of diagnostic detection. In this sense,…

  • Epidemiological characteristics of Omicron and Delta Sars-CoV-2 variant infection in Santiago, Chile

    Open AccessAndrea Mella-Torres, Andrea Mella‐Torres et al.ARTICLEFrontiers in Public Health2022

    The variant of concern (VOC) SARS-CoV-2 Omicron (B.1.1529) has been described as a highly contagious variant but less virulent than the current variant being monitored (VBM) Delta (B.1.617.2), causing fewer cases of hospitalizations, symptomatology, and deaths associated with COVID-19 disease. Although the epidemiological comparison of both variants has been previously reported in other countries, no report indicates their behavior and severity o…

  • Comparison of the First and Second Wave of Infections by Sars-CoV-2

    Open AccessClaudio Acuña‐Castillo, Claudio Acuña-Castillo et al.ARTICLEFrontiers in Public Health2022

    The current COVID-19 pandemic is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Many countries have reported the experience of at least two contagion waves, describing associated mortality rates and population behavior. The analysis of the effect of this pandemic in different localities can provide valuable information on the key factors to consider in the face of future massive infectious diseases. This work describe…

  • Description of Symptoms Caused by the Infection of the Sars-CoV-2 B.1.621 (Mu) Variant in Patients With Complete CoronaVac Vaccination Scheme

    Open AccessCarlos Barrera‐Avalos, Carlos Barrera-Avalos et al.ARTICLEFrontiers in Public Health2022

    Vaccine administration is one of the most efficient ways to control the current coronavirus disease 2019 (COVID-19) pandemic. However, the appearance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants can avoid the immunity generated by vaccines. Thus, in patients with a complete vaccine schedule, the infection by SARS-CoV-2 may cause severe, mild, and asymptomatic manifestations of the disease. In this case report, we descr…

  • The Rapid Antigen Detection Test for Sars-CoV-2 Underestimates the Identification of Covid-19 Positive Cases and Compromises the Diagnosis of the Sars-CoV-2 (K417N/T, E484K, and N501Y) Variants

    Open AccessCarlos Barrera-Avalos, Roberto Luraschi et al.ARTICLEFrontiers in Public Health2022

    Timely detection of severe acute respiratory syndrome due to coronavirus 2 (SARS-CoV-2) by reverse transcription quantitative polymerase chain reaction (RT-qPCR) has been the gold- strategy for identifying positive cases during the current pandemic. However, faster and less expensive methodologies are also applied for the massive diagnosis of COVID-19. In this way, the rapid antigen test (RAT) is widely used. However, it is necessary to evaluate …
