This article addresses the critical need for understanding the dynamics of COVID-19 transmission and the role of booster vaccinations in managing the pandemic. Despite widespread vaccination efforts, the emergence of new variants and the waning of immunity over time necessitate more effective strategies. A fractional-order mathematical model using Caputo-Fabrizio derivatives was developed to analyze the impact of booster doses, symptomatic and asymptomatic infections, and quarantine measures.

Objectives: During the COVID-19 pandemic, free on-demand testing was promoted in the US. This study was undertaken to support or refute the hypothesis that negative SARS-CoV-2 tests led to travel that exposed travelers to the virus in US states.
Methods: Data on daily trips outside households based on cell phone movement were matched by date to negative tests, positive tests, subsequent COVID-19 cases, and deaths lagged at various intervals in 49 US states during the first 16 months of the pandemic.

Background: The lockdown due to the COVID-19 pandemic, imposed in many countries in 2021, led to social isolation and the interruption of many activities that were useful in stimulating cognition. The impact of these changes has been particularly severe in older subjects with cognitive impairment.
Methods: The present study aimed to investigate the effects of lockdown on Alzheimer's disease patients (in cognition, behavior, and autonomy) and on their caregivers (in emotions, burden, and quality of life).

Objective: The coronavirus disease-2019 (COVID-19) pandemic's social isolation has significantly impacted mental health, increasing depression and anxiety. This study explores the effects of social isolation on both humans and mice, focusing on behavioral changes and hippocampal protein expression. It also investigates genetic alterations through single-cell RNA and whole-genome sequencing (WGS).
