Summary

On 11 March 2020, the World Health Organization declared COVID-19 a global pandemic, and the disease now affects nearly every country and region. Caused by SARS-CoV-2, COVID-19 continues nearly 18 months later to present significant challenges to health systems and public health in both hemispheres, as well as the economies of every country. The morbidity and mortality of the infection caused by SARS-CoV-2 has been significant, and various waves of disease outbreaks initially overwhelmed many hospitals and clinics and continue to do so in many countries. This influences everyone, and public health countermeasures have been dramatic in terms of their impact on employment, social systems, and mental health. This entry collection aims to gather diverse fields about COVID-19, including in epidemiology, public health, medicine, genetics, systems biology, informatics, data science, engineering, sociology, anthropology, nursing, environmental studies, statistics, and psychology.

DNA Damage Response and COVID-19
COVID-19 is an infectious disease caused by the SARS-CoV-2 coronavirus and characterized by an extremely variable disease course, ranging from asymptomatic cases to severe illness. Our cells develop DNA lesions on a daily basis. These lesions can inhibit basic cellular processes, such as genome replication and transcription, and if they are not repaired properly, they could result in mutations or genome aberrations, thereby posing a threat to the cell or even to the viability of a particular organism.

Ivermectin for the Treatment and/or Prophylaxis of COVID-19
The pathogenesis of Coronavirus Disease 2019 (COVID-19) is initiated by viral entry through the angiotensin-converting enzyme 2 (ACE-2) receptor in the host cell. After entry, RNA is translated into viral proteins upon its release in the cytoplasm. The resulting symptoms and clinical manifestations include fever, headache, myalgia, and respiratory symptoms. Several drugs have been and continue to be repurposed for the prophylaxis and treatment of COVID-19. Ivermectin (IVM) belongs to the naturally occurring family of avermectins produced by the bacterium Streptomyces avermitilis. Its broad antiparasitic spectrum is achieved through the hyperpolarization of the invertebrate’s cell membrane, with subsequent parasite paralysis. It was tested and confirmed for its in vitro antiviral activity against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Trials have put IVM to test for both the treatment and prophylaxis of COVID-19, as well as its potential role in combination therapy. Additionally, the targeted delivery of IVM was studied in animals and COVID-19 patients.

Miscellaneous Natural Products for COVID-19
Natural medicine has proven its effectiveness against various illnesses. Most of the pharmaceutical agents currently used can trace their origin to the natural products in one way, shape, or form. Using natural products, which is part of various traditional medical systems to prevent and/or treat diseases, dates back thousands of years in different parts of the world.

Dietary Supplements on Inflammatory Markers and SARS-CoV-2 Infection
A key characteristic of severe presentations of acute SARS-CoV-2 infection involves overactive host inflammatory responses, with a substantial proportion of severe outcomes such as hospitalizations and deaths from COVID-19 linked to hyper-inflammation. Inflammation and oxidative stress play pivotal roles in the progression of infectious diseases including COVID-19. Evidence suggests that high sensitivity (hs) C-reactive protein (CRP), interleukin (IL)-6, and matrix metalloproteinases (MMPs) are among the most important biomarkers of COVID-19 severity, similar to the chronic conditions involved in vascular aging. Lactate dehydrogenase (LDH) and hsCRP are also biomarkers of respiratory failure in patients with COVID-19. Furthermore, it is well established that elevated levels of other inflammatory markers are common in COVID-19 patients. These markers include IL-1β, IL-7, IL-8, IL-18, interferon (IFN)-γ, tumor necrosis factor (TNF)-α, procalcitonin (PCT), serum ferritin, and erythrocyte sedimentation rate (ESR).

Impact of Lockdown on PM Charecterisitcs
Air is a diverse mixture of gaseous and suspended solid particles. Several new substances are being added to the air daily, polluting it and causing human health effects. Particulate matter (PM) is the primary health concern among these air toxins. The World Health Organization (WHO) addressed the fact that particulate pollution affects human health more severely than other air pollutants. The spread of air pollution and viruses, two of the millennium’s most serious concerns, have been linked closely.

COVID-19 Vaccines Related User’s Response Categorization
Respiratory viruses known as coronaviruses infect people and cause death. The multiple crown-like spikes on the virus’s surface give them the name “corona”. The pandemic has resulted in a global health crisis and it is expected that every year people will have to fight against different COVID-19 variants. In this critical situation, the existence of COVID-19 vaccinations provides hope for mankind. Despite severe vaccination campaigns and recommendations from health experts and the government, people have perceptions regarding vaccination risks and share their views and experiences on social media platforms. Social attitudes to these types of vaccinations are influenced by their positive and negative effects. The analysis of such opinions can help to determine social trends and formulate policies to increase vaccination acceptance.

Endocrine Aspects of ICU-Hospitalized COVID-19 Patients
The unprecedented scale of the current SARS-CoV-2/COVID-19 pandemic has led to an extensive—yet fragmented—assessment of its endocrine repercussions; in many reports, the endocrine aspects of COVID-19 are lumped together in intensive care unit (ICU) patients and non-ICU patients.

Capillary Leak Syndrome in COVID-19 and Cardiometabolic Disease
COVID-19 is a disease with multi-faceted clinical features, which vary from mild disease to fatal outcomes. The severity of the disease is associated with chronic low-grade inflammation and endothelial dysfunction underlying cardiometabolic diseases. Capillary leak, through endothelial hyperpermeability to proteins and the induction of pro-inflammatory, pro-coagulant pathways, has emerged as a pivotal pathogenetic factor of SARS-CoV-2 infection in cardiometabolic patients and as major etiology of hypoalbuminemia in severe COVID-19 cases. A great body of evidence supports the association of this condition with underlying metabolic derangement, and few remarkable indications regarding the role of metabolic disease in the incidence of systemic capillary leak syndrome flares have been noted. Further studies are needed to consolidate these findings and enlighten the pathophysiology behind them.

COVID-19-Related Acute Respiratory Distress Syndrome
Lower respiratory tract invasion by severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) results in widespread damage of type II alveolar and pulmonary capillary endothelial cells, disruption of the alveolar-capillary barrier, activation of coagulation, and diffuse thrombogenesis amplified by recruited monocytes and neutrophils and concurrent hypofibrinolysis. These pathobiological mechanisms are associated with a distinct form of acute respiratory distress syndrome (ARDS), characterized by relatively high lung compliance, progressively worsening hypoxemia, low potential for lung recruitment, hyperperfusion of nonaerated lung tissue, and diffuse small-vessel thrombosis.

Extracellular Vesicle-Based Therapeutics against SARS-CoV-2
Extracellular vesicles (EVs) , comprising a variety of nano-scale vesicles ranging from 50 to 1000 nm in size, are released from all types of cells carrying a variety of lipids, proteins, and nucleic acids in a more protective manner than un-enveloped circulating biomolecules such as antibodies and cytokines from cellular DNases, RNases, proteases, and other degrading materials, due to the presence of the lipid bilayer membrane. EVs contribute to the dissemination and persistence of genetic material and proteins of SARS-CoV-2 due to the similarity in the entrance, budding, and mechanisms of biogenesis during infection.
