There is pressing urgency to understand the pathogenesis of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which causes Coronavirus disease 2019 (COVID-19). The tissue tropism of SARS-CoV-2 includes not only the lung but also the vascular and integumentary systems. Angiotensin-converting enzyme 2 (ACE2) appears to be the key functional receptor for the virus. There is a prominent innate immune response to SARS-CoV-2 infection, including inflammatory cytokines, chemokines, the complement system, and acute phase proteins. The pathophysiologic significance of SARS-COV-2 and host immune system interaction, and COVID-19-associated coagulopathy instigating microvascular injury syndrome mediated by activation of complement pathways, and an associated procoagulant state is important for wound care professionals to understand.

Introduction: Indigenous connectedness is an impetus for health, well-being, self-confidence, cultural preservation, and communal thriving. When this connectedness is disrupted, the beliefs, values, and ways of life that weave Indigenous communities together is threatened. In the Spring of 2020, the COVID-19 virus crept into Tribal Nations across the United States and exacerbated significant health-related and educational inequities.

The hemostatic system prevents and stops bleeding, maintaining circulatory integrity after injury. It directly interacts with the complement system, which is key to innate immunity. In coronavirus disease 2019 (COVID-19), dysregulation of the hemostatic and complement systems has been associated with several complications.

Background: Drug repurposing has become a widely adopted strategy to minimise research time, costs, and associated risks. Combinations of protease inhibitors such as lopinavir and darunavir with ritonavir have been repurposed as treatments for COVID-19. Although lopinavir-ritonavir (LPV/r) and darunavir-ritonavir (DRV/r) have shown efficacy against COVID-19, the results in human studies have been inconsistent.

Coronavirus disease 2019 (COVID-19) and influenza A outbreaks have spread rapidly in China. It is difficult to accurately differentiate these two different respiratory tract infections on the basis of their similar early-stage symptoms and lymphocytopenia. In the present study, the age, sex and white blood cell, neutrophil, lymphocyte, monocyte and eosinophil counts, as well as the neutrophil-to-lymphocyte ratio (NLR) of 201 outpatients with confirmed COVID-19 and 246 outpatients with influenza A were investigated and compared.

Objective: Stigma influences perceptions of mental illness and novel diseases like coronavirus disease-2019 (COVID-19), often impeding healthcare access despite advancements in medical treatment. This study compares the stigma associated with COVID-19 and mental illness to identify factors that could help reduce stigma.
Methods: An online survey was conducted in May 2023 among 1,500 participants aged 19 to 65 in South Korea, using a panel from Embrain, an online survey service.
