Coronavirus Infection

Ten years have elapsed since the severe acute respiratory syndrome outbreak, which resulted in more than 8000 cases worldwide with more than 700 deaths. Recently, a new coronavirus, the Middle East Respiratory Syndrome Coronavirus emerged, causing serious respiratory cases and death. By the end of August 2013, 108 cases including 50 deaths were reported. The authors discuss a coronavirus-associated severe acute respiratory syndrome, which was detected in Hungary in 2005 and highlight its significance in 2013. In 2005 the patient was hospitalized and all relevant clinical and microbiological tests were performed. Based on the IgG antibody positivity of the serum samples, the patient was diagnosed as having severe acute respiratory syndrome coronavirus infection in the past. The time and source of the infection remained unknown. The condition of the patient improved and he was discharged from the hospital. The case raises the possibility of infections in Hungary imported from remote areas of the world and the importance of thorough examination of patients with severe respiratory syndrome with unknown etiology.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is causing a pandemic of coronavirus disease 2019 (COVID-19). The worldwide transmission of COVID-19 from human to human is spreading like wildfire, affecting almost every country in the world. In the past 100 years, the globe did not face a microbial pandemic similar in scale to COVID-19. Taken together, both previous outbreaks of other members of the coronavirus family (severe acute respiratory syndrome (SARS-CoV) and middle east respiratory syndrome (MERS-CoV)) did not produce even 1% of the global harm already inflicted by COVID-19. There are also four other CoVs capable of infecting humans (HCoVs), which circulate continuously in the human population, but their phenotypes are generally mild, and these HCoVs received relatively little attention. These dramatic differences between infection with HCoVs, SARS-CoV, MERS-CoV, and SARS-CoV-2 raise many questions, such as: Why is COVID-19 transmitted so quickly? Is it due to some specific features of the viral structure? Are there some specific human (host) factors? Are there some environmental factors? The aim of this review is to collect and concisely summarize the possible and logical answers to these questions.

When the World Health Organization declared the end of the global outbreak of severe acute respiratory syndrome (SARS) on the 5 July 2003, more than 8000 cases with over 800 fatalities had been reported in 32 countries worldwide and financial costs to the global economy were close to $US40 billion1,2. Coronaviruses were identified as being responsible for the outbreaks of both SARS and Middle East respiratory syndrome (MERS, the latter in 2013). Subsequently, bats (order Chiroptera) were identified as the natural hosts for a large number of novel and genetically diverse coronaviruses, including the likely ancestors to SARS-like and MERS-like coronaviruses3–8.

ABSTRACT An indirect immunofluorescent assay (Euroimmun AG, Luebeck, Germany) was used to investigate the avidity of immunoglobulin G (IgG), IgM, IgA, and total Ig (IgGAM) antibody responses to severe acute respiratory syndrome coronavirus (SARS CoV) infections. Serial serum samples from eight patients collected during the first, third, and ninth months after the onset of infection were evaluated. It was found that low-avidity IgG antibodies were detected in 15/15 (100%), 1/5 (20%), and 0/8 (0%) serum samples collected during the first, third, and ninth months after the onset of symptoms, respectively. Low-avidity antibodies of IgA and IgM subclasses were detected in 14/14 (100%) and 3/14 (21%) serum samples, respectively, collected in the first month after the onset of infection. However, IgA antibodies remained low in avidity in a proportion of patients even during late convalescence. As a consequence, IgG antibody avidity assays gave better discrimination between acute-phase and late-convalescent-phase serum samples than IgM, IgA, or IgGAM assays. In two of these patients, sequential serum samples were also tested for IgG avidity against human CoV strains OC43 and 229E in parallel. While SARS CoV infections induced an anamnestic IgG antibody response to the 229E and OC43 viruses, these cross-reactive antibodies remained of high avidity from early (the first month) postinfection. The results showed that assays to detect low-avidity antibody may be useful for discriminating early from late antibody responses and also for distinguishing anamnestic cross-reactive antibody responses from primary specific responses. This may be useful in some clinical situations.

The world is currently going through a disastrous event and a catastrophic upheaval caused by the coronavirus disease 2019 (COVID-19). The pandemic has resulted in loss of more than 150000 deaths across the globe. Originating from China and spreading across all continents within a short span of time, it has become a matter of international emergency. Different agencies are adopting diverse approaches to stop and spread of this viral disease but still now nothing confirmatory has come up. Due to lack of vaccines and proper therapeutic drugs, the disease is still spreading like wild fire without control. An Old but very promising method- the convalescent plasma therapy could be the key therapy to stop this pandemic. This method has already proven its mettle on several occasions previously and has been found to be effective in curing the pandemics induced by Ebola, severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the same group of β-Coronavirus that has resulted in the above diseases. Therefore, the role of plasma therapy is being explored for treatment of this disease. In this review, we have mainly focused on the role of convalescent plasma therapy and why its use should be promoted in fight against COVID-19, as it could turn out to be a game changer.

The Creation

The creation of the Islamic State in Iraq and Sham (ISIS) changed the nature of jihadism worldwide. For a few years (2014–2017) it exemplified the destructive capacity of jihadism and created a new utopia aimed at restoring the past greatness and glory of the former caliphate. It also attracted tens of thousands of young wannabe combatants of faith (mujahids, those who make jihad) toward Syria and Iraq from more than 100 countries. Its utopia was dual: not only re-creating the caliphate that would spread Islam all over the world but also creating a cohesive, imagined community (the neo-umma) that would restore patriarchal family and put an end to the crisis of modern society through an inflexible interpretation of shari‘a (Islamic laws and commandments). To achieve these goals, ISIS diversified its approach. It focused, in the West, on the rancor of the Muslim migrants’ sons and daughters, on exoticism, and on an imaginary dream world and, in the Middle East, on tribes and the Sunni/Shi‘a divide, particularly in the Iraqi and Syrian societies.

Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic since March 2020 and led to significant challenges to over 200 countries and regions all over the world. The establishment of highly pathogenic coronavirus animal model is beneficial for the study of vaccines and pathogenic mechanism of the virus. Laboratory mice, Syrian hamsters, Non-human primates and Ferrets have been used to establish animal models of emerging coronavirus infection. Different animal models can reproduce clinical infection symptoms at different levels. Appropriate animal models are of great significance for the pathogenesis of COVID-19 and the research progress related to vaccines. This review aims to introduce the current progress about experimental animal models for SARS-CoV-2, and collectively generalize critical aspects of disease manifestation in humans and increase their usefulness in research into COVID-19 pathogenesis and developing new preventions and treatments.

The disaster due to the novel coronavirus disease 2019 (COVID-19) around the world has made investigators enthusiastic about working on different aspects of COVID-19. However, although the pandemic of COVID-19 has not yet ended, it seems that COVID-19 compared to the other coronavirus infections (the Middle East Respiratory Syndrome [MERS] and Severe Acute Respiratory Syndrome [SARS]) is more likely to target the heart. Comparing the previous presentations of the coronavirus family and the recent cardiovascular manifestations of COVID-19 can also help in predicting possible future challenges and taking measures to tackle these issues.

ABSTRACT Severe acute respiratory syndrome (SARS) is a recently emerged human disease associated with pneumonia. Inapparent infection with SARS coronavirus (CoV) is not well characterized. To develop a safe, simple, and reliable screening method for SARS diagnosis and epidemiological study, two recombinant SARS-CoV nucleocapsid proteins (N′ protein and NΔ121 protein) were expressed in Escherichia coli, purified by affinity chromatography, and used as antigens for indirect, immunoglobulin G enzyme-linked immunosorbent assays (ELISA). Serum samples collected from healthy volunteers and SARS patients in Vietnam were used to evaluate the newly developed methods. The N′ protein-based ELISA showed a highly nonspecific reaction. The NΔ121 protein-based ELISA, with a nonspecific reaction drastically reduced compared to that of the nearly-whole-length N′ protein-based ELISA, resulted in higher rates of positive reactions, higher titers, and earlier detection than the SARS-CoV-infected cell lysate-based ELISA. These results indicate that our newly developed SARS-CoV NΔ121 protein-based ELISA is not only safe but also a more specific and more sensitive method to diagnose SARS-CoV infection and hence a useful tool for large-scale epidemiological studies. To identify inapparent SARS-CoV infections, serum samples collected from health care workers (HCWs) in Vietnam were screened by the NΔ121 protein-based ELISA, and positive samples were confirmed by a virus neutralization test. Four out of 149 HCWs were identified to have inapparent SARS-CoV infection in Vietnam, indicating that subclinical SARS-CoV infection in Vietnam is rare but does exist.
