In this article, a nonlinear fractional bi-susceptible [Formula: see text] model is developed to mathematically study the deadly Coronavirus disease (Covid-19), employing the Atangana-Baleanu derivative in Caputo sense (ABC). A more profound comprehension of the system's intricate dynamics using fractional-order derivative is explored as the primary focus of constructing this model. The fundamental properties such as positivity and boundedness, of an epidemic model have been proven, ensuring that the model accurately reflects the realistic behavior of disease spread within a population.

Mice are one of the most common biological models for laboratory use. However, wild-type mice are not susceptible to COVID-19 infection due to the low affinity of mouse ACE2, the entry protein for SARS-CoV-2. Although mice with human ACE2 (hACE2) driven by Ace2 promoter reflect its tissue specificity, these animals exhibit low ACE2 expression, potentially limiting their fidelity in mimicking COVID-19 manifestations and their utility in viral studies.

This commentary provides a reflection on the impact of the COVID-19 pandemic on adolescents in the context of family dynamics, school environments, peer relationships, and civic engagement. Drawing from four systematic literature reviews, the commentary highlights key findings, such as the long-term effects of COVID-19 on adolescent development, mental health, and academic well-being. The need for future research is emphasized to assess how these cohort effects will evolve over time.

We discuss the paper recently published in Rheumatology Internationa. This article reflects on the prevalence of autoimmune rheumatic diseases (ARD) during the COVID-19 pandemic (2020-2023) and compares the same with the pre-pandemic period (2016-2019). We assume that SARS-CoV-2 triggers ARD.

To assess the impact of the SARS-CoV-2 booster dose on the immune response against COVID-19, we conducted a cross-sectional study in the Casablanca-Settat region of Morocco. The study included 2,802 participants from 16 provinces, all of whom had received three doses of a SARS-CoV-2 vaccine. IgG antibodies targeting the S1 RBD subunit of the SARS-CoV-2 spike protein were quantified using the SARS-CoV-2 IgG II Quant assay and measured on the Abbott Architect i2000SR instrument.
