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.

Impact of COVID-19 on Head and Neck Carcinoma
The COVID-19 pandemic has significantly impacted all public life and the global economy. Since its discovery, the disease has spread rapidly, which led to an unprecedented public health crisis and the adoption of extreme measures to limit community and hospital spread. As a result of a confluence of extraordinary circumstances caused by this pandemic, the doctrines of treatment for patients with head and neck carcinoma had to be reanalyzed, guaranteeing the well-being of both patients and health professionals as well as society itself.

Syphilis and COVID-19
The syphilis and COVID-19 pandemics have marked a turning point in the history of mankind. The aim of this review is to analyze what two pandemics caused by different diseases have in common.

SARS-CoV-2 and HIV Surface Envelope Glycoproteins
Although very different, in terms of their genomic organization, their enzymatic proteins, and their structural proteins, HIV and SARS-CoV-2 have an extraordinary evolutionary potential in common. Faced with various selection pressures that may be generated by treatments or immune responses, these RNA viruses demonstrate very high adaptive capacities, which result in the continuous emergence of variants and quasi-species. HIV and SARS-CoV-2 first recognize a lipid raft microdomain that acts as a landing strip for viral particles on the host cell surface. In the case of mucosal cells, which are the primary targets of both viruses, these microdomains are enriched in anionic glycolipids (gangliosides) forming a global electronegative field. Both viruses use lipid rafts to surf on the cell surface in search of a protein receptor able to trigger the fusion process. This implies that viral envelope proteins are both geometrically and electrically compatible to the biomolecules they select to invade host cells.

Parasitic Connection between COVID-19 and Diarylamidines
As emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants (Omicron) continue to outpace and negate combinatorial vaccines and monoclonal antibody therapies targeting the spike protein (S) receptor binding domain (RBD), the appetite for developing similar COVID-19 treatments has significantly diminished, with the attention of the scientific community switching to long COVID treatments.

Immune Response to SARS-CoV-2 and mRNA Vaccines
The SARS-CoV-2 (severe acute respiratory syndrome coronavirus responsible for the COVID-19 disease) uses the Spike proteins of its envelope for infecting target cells expressing on the membrane the angiotensin converting enzyme 2 (ACE2) enzyme that acts as a receptor. To control the pandemic, genetically engineered vaccines have been designed for inducing neutralizing antibodies against the Spike proteins. These vaccines do not act like traditional protein-based vaccines, as they deliver the message in the form of mRNA or DNA to host cells that then produce and expose the Spike protein on the membrane (from which it can be shed in soluble form) to alert the immune system. Since the genetically engineered vaccines have been modified to be more stable and because they are distributed via liponanoparticles to various tissues and organs, this type of products may cause unforeseen serious adverse effects.

Angiotensin-Converting Enzyme 2 (ACE-2) in COVID-19
The genetic variants of HLAs (human leukocyte antigens) play a crucial role in the virus–host interaction and pathology of COVID-19. The genetic variants of HLAs not only influence T cell immune responses but also B cell immune responses by presenting a variety of peptide fragments of invading pathogens. Peptide cocktail vaccines produced by using various conserved HLA-A2 epitopes provoke substantial specific CD8+ T cell responses in experimental animals. The HLA profiles vary among individuals and trigger different T cell-mediated immune responses in COVID-19 infections.

Protection of Patient Data in Digital Oral
The use of digital health technologies, including telemedicine and teledentistry, has become a necessity in healthcare due to the SARS-CoV-19 pandemic. These technologies allow for the reduction of the workload of healthcare providers and the improvement of patient outcomes in cases of remote monitoring, diagnosis, and communication. While there are no doubtful benefits, there are some counterparts, such as concerns about clinical risks, data security, and privacy protection.

Humanitarian Activities against COVID-19 Disruption
The COVID-19 pandemic has affected more than 214 countries across the world, disrupting the supply of essential commodities. As the pandemic has spread, humanitarian activities (HAs) have attempted to manage the various situation but appear ineffective due to lack of collaboration and information sharing, inability to respond towards disruption, etc. Developing a sustainable humanitarian supply chain (HSC) for managing disasters/emergencies can be viewed as an extension of the traditional supply chain. Thus, sustainable HSCs have evolved as a specialized discipline with a focus on social sustainability.

Extracellular Vesicles for COVID-19
COVID-19 is an infectious disease caused by the novel coronavirus (SARS-CoV-2) that first appeared in late 2019 and has since spread across the world. It is characterized by symptoms such as fever, cough, and shortness of breath and can lead to death in severe cases. To help contain the virus, measures such as social distancing, handwashing, and other public health measures have been implemented. Vaccine and drug candidates, such as those developed by Pfizer/BioNTech, AstraZeneca, Moderna, Novavax, and Johnson & Johnson, have been developed and are being distributed worldwide. Clinical trials for drug treatments such as remdesivir, dexamethasone, and monoclonal antibodies are underway and have shown promising results.

mRNA Vaccines against SARS-CoV-2
Coronaviruses are single-stranded positive-sense RNA (+ssRNA) viruses belonging to the Coronaviridae family. Their genome encodes replicase/transcriptase proteins, structural proteins and a set of non-structural proteins linked to their virulence and proofreading activities of the replicase complex.
