Viral Surface

Coronaviruses are a large family of viruses that usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. They were named according to the shape of glycoprotein spikes present on the viral surface and resembling to the solar corona. The first coronaviruses identified in human were HCoV 229E and the HCoV OC43, known also as β-coronavirus. This virus family has become increasingly important and received more attention within scientific community in the past two decades because of three new viruses that can cause serious, even fatal, disease. These are SARS coronavirus (SARS-CoV), which emerged in November 2002 and caused severe acute respiratory syndrome (SARS); Middle East respiratory syndrome (MERS) caused by the MERS coronavirus (MERS-CoV), identified in September 2012 and continues to cause sporadic and localized outbreaks. The third novel coronavirus to emerge in this century is called SARS-CoV-2. This chapter will describe the history of the coronavirus family discovery, emergence, and classification of the main coronaviruses.

Subjective Alertness

Abstract The present study examined whether volunteers with common colds showed impairments in objective and subjective indicators of alertness. All the volunteers (N = 81) were tested when healthy to provide baseline data for mood, simple and choice reaction time tasks, and an anti-saccadic eye movement task. When subjects developed a cold (N = 17) they returned to the laboratory and repeated the procedure. Volunteers (N = 64) who remained healthy over a 10-week period were recalled as controls. The results showed that those with colds felt significantly less alert and had significantly slower simple and choice reaction times and eye movements. This extends earlier research and shows that electrophysiological measures may also be of use in assessing the behavioral changes induced by upper respiratory tract illnesses.

Human Coronaviruses

Dear Reader, Coronaviruses are a large family of zoonotic viruses, that is, the virus is transmitted from animals to humans. Although several common human coronaviruses are known, and usually lead upon infection to mild to moderate upper-respiratory tract illnesses, some coronaviruses cause epidemics. Severe Acute Respratory Syndrome (SARS-CoV) erupted in February 2003 following transmission from civet cats to humans. Middle East Respiratory Syndrome (MERS-CoV) surfaced in April 2012 following transmission from dromedary camels to humans. However, both these epidemics pale into insignificance in the context of the havoc currently being caused by an hitherto unknown coronavirus, now named as COVID-19 and which is first assumed to have started mid-December 2019 in Wuhan, China. It is strongly suspected that COVID-19 was transmitted from bats to humans.

The article provides a philosophical analysis of the tropological theory of the history of H. White. The researcher claims that history is a specific kind of literature, and the historical works is the connection of a certain set of research and narrative operations. The first type of operation answers the question of why the event happened this way and not the other. The second operation is the social description, the narrative of events, the intellectual act of organizing the actual material. According to H. White, this is where the set of ideas and preferences of the researcher begin to work, mainly of a literary and historical nature. Explanations are the main mechanism that becomes the common thread of the narrative. The are implemented through using plot (romantic, satire, comic and tragic) and trope systems – the main stylistic forms of text organization (metaphor, metonymy, synecdoche, irony). The latter decisively influenced for result of the work historians. Historiographical style follows the tropological model, the selection of which is determined by the historian’s individual language practice. When the choice is made, the imagination is ready to create a narrative. Therefore, the historical understanding, according to H. White, can only be tropological. H. White proposes a new methodology for historical research. During the discourse, adequate speech is created to analyze historical phenomena, which the philosopher defines as prefigurative tropological movement. This is how history is revealed through the art of anthropology. Thus, H. White’s tropical history theory offers modern science f meaningful and metatheoretically significant. The structure of concepts on which the classification of historiographical styles can be based and the predictive function of philosophy regarding historical knowledge can be refined.

Coronaviruses (CoVs) are a well-known group of viruses in veterinary medicine. We currently know four genera of Coronavirus, alfa, beta, gamma, and delta. Wild, farmed, and pet animals are infected with CoVs belonging to all four genera. Seven human respiratory coronaviruses have still been identified, four of which cause upper-respiratory-tract diseases, specifically, the common cold, and the last three that have emerged cause severe acute respiratory syndromes, SARS-CoV-1, MERS-CoV, and SARS-CoV-2. In this review we briefly describe animal coronaviruses and what we actually know about SARS-CoV-2 infection in farm and domestic animals.

Abstract Background We performed a search in the PubMed databases, Web of Science, LILACS, MEDLINE, SciELO, and Cochrane Library using the keywords COVID-19, Novel coronavirus, corona, 2019-nCoV, SARS-CoV-2, ENT, nose, anosmia, hyposmia, smell, olfactory, ORL, different ENT related symptoms. We reviewed published and peer-reviewed studies that reported the ENT manifestations in COVID-19 laboratory-confirmed positive patients. Main text Within the included 2549 COVID-19 laboratory-confirmed positive patients, smell affection was reported in 1453 patients (57%). The other reported ENT manifestations were taste disorder (49.2%), headache (42.8%), nasal blockage (26.3%), sore throat (25.7%), runny nose or rhinorrhea (21.3%), upper respiratory tract infection (URTI) (7.9%), and frequent sneezing (3.6%). Conclusion Smell affection in COVID-19 is common and could be one of the red flag signs in COVID-19 infection. With a sensitivity of utilized questionnaire in smell identification, a homogenous universal well-defined COVID-19 questionnaire is needed to make the COVID-19 data collection more sensible.

In September 2009, an outbreak of 2009 pandemic influenza A(H1N1) took place in a Finnish garrison. In November 2009, we performed a serological survey among 984 recruits undergoing their military service at the garrison and related the results to self-reported upper respiratory tract infection (URTI) with or without fever. Of 346 volunteers who donated a blood sample, 169 (49%) had pandemic influenza A(H1N1) virus-specific antibodies. Of those, 84 (50%) reported no recent history of URTI, suggesting that a major part of those infected with pandemic influenza A(H1N1) virus may be asymptomatic.

Coronaviruses (CoVs) are a group of viral pathogens that infect mammals and birds. The presentation in humans is typically that of a mild upper respiratory tract infection, similar to the common cold. However, in recent years, dramatic attention has arisen for more lethal members of this viral family (e.g., severe acute respiratory syndrome [SARS-CoV], Middle East respiratory syndrome [MERS-CoV], and coronavirus disease 2019 [COVID-19]). The epidemiology, clinical presentation, diagnosis, and management of these viruses are discussed in this review. Importantly, new guideline tables from the Centers for Disease Control and Prevention, as well as the World Health Organization are provided at the conclusion of the review. This review contains 12 tables, 3 figure and 48 references. Keywords: Coronavirus, severe acute respiratory distress syndrome (SARS), Middle East respiratory syndrome (MERS), COVID-19, respiratory infection, antiviral, real-time polymerase chain reaction
