Up until, June 13, 2020, >7,500,000 cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and >400,000 deaths, across 216 countries, have been confirmed by the World Health Organization (WHO). With reference to the two previous beta-CoV outbreaks (SARS-CoV and middle east respiratory syndrome [MERS]), this paper examines the pathophysiological and clinical similarities seen across all three CoVs, with a special interest in the neuroinvasive capability and subsequent consequences for patients with primary or metastatic brain tumors. More widely, we examine the lessons learned from the management of such large-scale crises in the past, specifically looking at the South Korean experience of MERS and the subsequent shift in disaster management response to SARS-CoV-2, based on prior knowledge gained. We assess the strategies with which infection prevention and control can, or perhaps should, be implemented to best contain the spread of such viruses in the event of a further likely outbreak in the future.

Porcine circovirus type 2 (PCV2) is the major causative agent of postweaning multisystemic wasting syndrome which leads to significant economic losses in the global swine industry. In China, there is a widespread dissemination of PCV2 infection in the pig population. Serological diagnosis of the disease is considered as an effective control measure.

Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is a common critical illness. Supportive therapy is still the main strategy for ALI/ARDS. Macrophages are the predominant immune cells in the lungs and play a pivotal role in maintaining homeostasis, regulating metabolism, and facilitating tissue repair.

Background: is one of the neglected tropical diseases. We aimed to verify the genetic diversity of with attention to clinical features of the infection in patients using the 1 gene and DNA sequencing.
Methods: Using parasitological methods, was isolated from stool samples of patients who had been referred to Tehran University of Medical Sciences, Tehran, Iran.

Background: Premature infants are at high risk for neonatal respiratory distress syndrome (RDS) and secondary infections. This study aims to investigate the association between immunoinflammatory markers-the systemic immune inflammation index (SII), systemic inflammation response index (SIRI), and neutrophil-to-albumin ratio (NAR)-and the risk of developing RDS in premature infants.
Methods: A total of 2164 premature infants were enrolled in this retrospective study.

Understanding the early interactions between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human airway epithelial cells is essential for unraveling viral replication and spread mechanisms. In this study, we investigated the early dynamics of airway epithelial cells during SARS-CoV-2 infection using well-differentiated human nasal and tracheal epithelial cell cultures by incorporating three publicly available single-cell RNA sequencing datasets. We identified a previously uncharacterized cell population, termed virus-rich intermediate (VRI) cells, representing an intermediate differentiation stage between basal and ciliated cells.
