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.

Cerebrovascular and Neurological Dysfunction
The recently discovered novel coronavirus, SARS-CoV-2 (COVID-19 virus), has brought the whole world to a standstill with critical challenges, affecting both health and economic sectors worldwide. Although initially, this pandemic was associated with causing severe pulmonary and respiratory disorders, recent case studies reported the association of cerebrovascular-neurological dysfunction in COVID-19 patients, which is also life-threatening. Several SARS-CoV-2 positive case studies have been reported where there are mild or no symptoms of this virus. However, a selection of patients is suffering from large artery ischemic strokes. Although the pathophysiology of the SARS-CoV-2 virus affecting the cerebrovascular system has not been elucidated yet, researchers have identified several pathogenic mechanisms, including a role for the ACE2 receptor. Therefore, it is extremely crucial to identify the risk factors related to the progression and adverse outcome of cerebrovascular-neurological dysfunction in COVID-19 patients. Since many articles have reported the effect of smoking (tobacco and cannabis) and vaping in cerebrovascular and neurological systems, and considering that smokers are more prone to viral and bacterial infection compared to non-smokers, it is high time to explore the probable correlation of smoking in COVID-19 patients. Herein, we have reviewed the possible role of smoking and vaping on cerebrovascular and neurological dysfunction in COVID-19 patients, along with potential pathogenic mechanisms associated with it.

Betacoronaviruses
In the 21st century, three highly pathogenic betacoronaviruses have emerged, with an alarming rate of human morbidity and case fatality. Genomic information has been widely used to understand the pathogenesis, animal origin and mode of transmission of coronaviruses in the aftermath of the 2002–2003 severe acute respiratory syndrome (SARS) and 2012 Middle East respiratory syndrome (MERS) outbreaks. Furthermore, genome sequencing and bioinformatic analysis have had an unprecedented relevance in the battle against the 2019–2020 coronavirus disease 2019 (COVID-19) pandemic, the newest and most devastating outbreak caused by a coronavirus in the history of mankind. Here, we briefly review the application of genomics and bioinformatics in the molecular epidemiology of pathogenic betacoronaviruses.

General Symptoms with COVID-19
Coronavirus disease 2019 (COVID-19) due to the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become an epidemiological threat and a worldwide concern. SARS-CoV-2 has spread to 210 countries worldwide and more than 3,000,000 confirmed cases and 228,513 deaths have been reported, while the number of both confirmed and fatal cases is continually increasing. COVID-19 is a viral disease that can affect every age group – from infants to the elderly – resulting in a wide spectrum of various clinical manifestations. COVID-19 might present different degrees of severity – from mild or even asymptomatic carriers, even to fatal cases. The most common complications include pneumonia and acute respiratory distress syndrome. Fever, dry cough, muscle weakness, and chest pain are the most prevalent and typical symptoms of COVID-19. However, patients might also present atypical symptoms that can occur alone, which might indicate the possible SARS-CoV-2 infection. The aim of this paper was to review and summarize all of the findings regarding clinical manifestations of COVID-19 patients and those include respiratory, neurological, olfactory and gustatory, gastrointestinal, ophthalmic, dermatological, cardiac, and rheumatologic manifestations, as well as specific symptoms in pediatric patients.

Management Strategies for COVID-19
The emergence of a novel human coronavirus (SARS-CoV-2) causing severe contagious respiratory tract infections presents a serious threat to public health worldwide. Moreover, no specific antiviral agents are available against this disease known as COVID-19. Therefore, scientific, economic and social measurements are urgently needed for an effective pandemic containment. In the present work, we reviewed recent findings from literature about COVID-19 prophylaxis and management, which could provide a clear view and help readers to be aware of the current pandemic situation.

Prevention and Treatment of COVID-19
Since the pandemic induced by the coronavirus SARS-CoV2 began to be spread throughout the whole world, many medical attempts to control the infection and avoid the high rate of mortality and morbidity have been made, collapsing the ICUs of many Hospitals. Many different treatments have been tested, but mortality reached very high values, especially in people in the middle/ elder age. Survivors usually develop important sequelae, even time after the infection had been controlled. In this article, we propose two different approaches to avoid the infection or mitigate their effects. One of them is based in the administration of GH, as preventive,  given its known effect on the production of lymphocytes and a high number of antibodies, as well as for helping in the recovery of the damaged organs. The other one is the administration of melatonin, both to prevent the infection and to act on inflammation once the disease is established. Both hormones are safe and can synergize when the damage to organs is established. GH administration has to be interrupted if the cytokine storm appears because the hormone can increase it. This is a novel approach that will be analyzed in extent, on scientific bases, throughout this article.

Salivary Diagnosis and Monitoring: COVID-19
The coronavirus disease 2019 (COVID-19) outbreak, caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global ongoing pandemic. Timely, accurate and non-invasive SARS-CoV-2 detection in both symptomatic and asymptomatic patients, as well as determination of their immune status, will facilitate effective large-scale pandemic control measures to prevent the spread of COVID-19. Saliva is a biofluid whose anatomical source and location is of particularly strategic relevance to COVID-19 transmission and monitoring. This review focuses on the role of saliva as both a foe (a common mode of viral transmission via salivary droplets and potentially aerosols) and a friend (as a non-invasive diagnostic tool for viral detection and immune status surveillance) in combating COVID-19.
