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.

Using Learning Gain to Evaluate Undergraduate Business Education
During the COVID-19 pandemic, universities across the globe replaced in-person teaching, with online teaching, because of widespread campus shutdowns. Through the application of a pre-existing learning gain model, it was possible to review the learning of one cohort of students receiving in-person teaching, and then the next cohort of students on the same course receiving the online teaching. Overall, a drop in perceived learning was reported from the cohort of students receiving online teaching. For female students, the most significant drop in learning related to practical understanding, whereas for male students, the most significant drop in learning related to theoretical knowledge.

Victims of Cyberbullying during COVID-19
In Chile, during the COVID-19 pandemic, reports of cyberbullying victimization increased for adolescents and younger adults. Cyber-victims—adolescents and young adults alike—are at greater risk for mental health problems such as depression as a result of this negative type of aggression. Cyberbullying victimization has negative consequences for mental health across ages. In Chile, during the pandemic, there were increasing reports of this behavior, which is connected with mental health. Thus, the need for prevention programs in the school and other contexts is significant.

Mathematics Anxiety at different schooling conditions during COVID-19
The COVID-19 pandemic has caused unprecedented changes in the educational system, requiring students to continually switch between distance and in-person learning conditions. During the second wave of COVID-19, 405 students, recruited from twelve middle schools of Catania province (Italy), completed an online version of the MeMa questionnaire, answering each item twice and imagining themselves to be, respectively, in distance and in-person learning conditions.

Positive and Solidarity Messages Amid the COVID-19 Pandemic
The COVID-19 outbreak has caused significant stress in daily lives, which potentially increases frustration, fear, and resentful emotions. Managing stress is complex, but helps to alleviate negative psychological effects. The COVID-19 outbreak, and its subsequent effects have increased the risk of poor mental health outcomes among the general population, which is a significant challenge for tackling the pandemic. Thus, creating a positive atmosphere in crisis communication is imperative.

Academics Work from Home during COVID-19 in South Africa
The continuing crisis caused by the novel coronavirus (COVID-19) outbreak has raised significant challenges for the higher education community globally. In South Africa, the government-forced lockdown measures and social distancing containment policy changed working arrangements across sectors and organisations. As a result, academics were forced to work from home (WFH), a task for which they were hardly prepared.

Myocarditis in Athletes Recovering from COVID-19
To assess the event rates of myocarditis detected by Cardiac Magnetic Resonance (CMR) in athletes who recovered from COVID-19. The prevalence of COVID-19-related myocarditis in the athletic population ranges from 1 to 4%. Even if the event rate is quite low, current screening protocols are helpful tools for a safe return to play to properly address CMR studies.

Early Childhood Education during the COVID-19 Pandemic
During the COVID-19 pandemic, schools and preschools worldwide have been suspended, causing many challenges for students, parents, and teachers. Through home-schooling, preschool children struggle to accept new (online) learning modes. Teachers need to acquire digital skills quickly to deliver online teaching, while parents need to take on the role of a tutor at home to facilitate their children’s learning.

Antimicrobial Masks as Personal protective equipment
Shortage of personal protective equipment (PPE) is often projected in response to public health emergencies such as infection outbreaks and pandemics. Respiratory protective devices (RPDs), namely medical face masks and respirators, are considered the last defence for the front-line healthcare workers. To contribute to the mitigation of RPDs shortage, new technology such as antimicrobial treated PPE that can reduce the risks of fomite during the donning and doffing process with an extended lifespan gets increasingly prevalent.

SARS-CoV-2 Affect Eyes
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has become a worldwide threat resulting in a pandemic in 2020. SARS-CoV-2 infection manifests itself as coronavirus disease 2019 (COVID-19) that is evidenced in a vast number of either specific or nonspecific symptoms. Except for typical (but nonspecific) symptoms such as fever, dry cough, or muscle weakness, the infected patients might also present atypical symptoms including neurological, dermatological, or ophthalmic manifestations.

Understanding COVID-19 Vaccines Today: Are T-cells Key Players?
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has heavily mutated since the beginning of the coronavirus-2019 (COVID-19) pandemic. In this regard, the so-called variants of concern (VOCs) feature mutations that confer increased transmissibility and evasion of antibody responses. The VOCs have caused significant spikes in COVID-19 cases, raising significant concerns about whether COVID-19 vaccines will protect against current and future variants. In this research, whereas the protection COVID-19 vaccines offer against the acquisition of infection appears compromised, the protection against severe COVID-19 is maintained. From an immunologic standpoint, this is likely underpinned by the maintenance of T-cell responses against VOCs. Therefore, the role of T-cells is essential to understanding the broader adaptive immune response to COVID-19, which has the potential to shape public policies on vaccine protocols and inform future vaccine design.
