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.

Empowerment Dynamics in Health Management and Entrepreneurship
Empowerment dynamics refer to the processes and factors that enhance individuals' capacity to control their personal and professional lives. This concept is especially significant in various contexts, such as the health management of chronic patients and entrepreneurship, particularly in post-crisis scenarios like the COVID-19 pandemic. It encompasses access to resources, support, and opportunities that help individuals overcome challenges and achieve their objectives. A theoretical framework was developed through PhD research, elucidating the mechanisms behind these challenges and their implications for fostering diversity, social innovation, and sustainability. This approach not only compares chronic patients with entrepreneurs and validates the theoretical framework in a group of chronic patients but also proposes practical strategies to harness diversity, innovation, and entrepreneurship in post-crisis contexts.

Redefining Vaccine Effectiveness through Lessons from SARS-CoV-2
Anti-SARS-CoV-2 vaccines have played a pivotal role in reducing the risk of developing severe illness from COVID-19, thus helping end the COVID-19 global public health emergency.  Intriguingly, as SARS-CoV-2 variants emerged, individuals who were fully vaccinated did get infected in high numbers, and viral loads in vaccinated individuals were as high as those in the unvaccinated.  However, vaccines undoubtedly offered protection against severe illness even without conferring immunity in the classical sense.  The lessons learned from anti-SARS-CoV-2 vaccines are a call to the medical community to revisit and redefine the concept of vaccine effectiveness.  This endeavor is likely to increase increase vaccine confidence, and thus bolster global health education efforts and preventive care.

COVID-19 Pandemic in Africa
On 30 January 2020, WHO declared COVID-19 a public health emergency of global concern. COVID-19 became pandemic on 11 March 2020, and spread unprecedently. No country was prepared to face its impact. Major fears started to be expressed for Africa, where dramatic consequences were expected, due to the weakness of health systems. The limited resources, in terms of qualified physicians, medical equipment and hospital infrastructures marked an undeniable inequality and highlighted the need to empower local capacity, raising the level of preparedness of African nations against infection outbreaks.

Statistical Analysis of Intensive Care Unit COVID-19 Data
COVID-19 caused a pandemic, due to its ease of transmission and high number of infections. The evolution of the pandemic and its consequences for the mortality and morbidity of populations, especially the elderly, generated several scientific studies and many research projects. Among them, researchers have the Predictive Models of COVID-19 Outcomes for Higher Risk Patients Towards a Precision Medicine (PREMO) research project. For such a project with many data records, it is necessary to provide a smooth graphical analysis to extract value from it.

Acute Myocardial Infarction during the COVID-19 Pandemic
Coronavirus disease 2019 (COVID-19) was a global pandemic with high mortality and morbidity that led to an increased health burden all over the world. Although the virus mostly affects the pulmonary tract, cardiovascular implications are often observed among COVID-19 patients and are predictive of poor outcomes. Increased values of myocardial biomarkers such as troponin I or NT-proBNP were proven to be risk factors for respiratory failure. Although the risk of acute coronary syndromes (ACSs) was greater in the acute phase of COVID-19, there were lower rates of hospitalization for ACSs, due to patients’ hesitation in presenting at the hospital. Hospitalized ACSs patients with COVID-19 infection had a prolonged symptom-to-first-medical-contact time, and longer door-to-balloon time. The mechanisms of myocardial injury in COVID-19 patients are still not entirely clear; however, the most frequently implicated factors include the downregulation of ACE2 receptors, endothelial dysfunction, pro-coagulant status, and increased levels of pro-inflammatory cytokines.

Nuclear Factor-Kappa B Pathway in SARS-CoV-2 Infection
COVID-19 is a global health threat caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is associated with a significant increase in morbidity and mortality. As a central player in the immune and inflammatory responses, modulating NF-κB activation could offer a strategic avenue for managing SARS-CoV-2 infection.
