Corona Virus Net is the web resource for anyone interested in Coronaviruses. Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (COVID-19) is a new strain that has not been previously identified in humans. Coronaviruses are zoonotic, meaning they are transmitted between animals and humans. Common signs of infection include respiratory symptoms, fever, cough, and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death. Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing. Also avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.

A pneumonia of unknown cause detected in Wuhan, China was first reported to the WHO on 31 December 2019. The outbreak of COVID-19 was declared a Public Health Emergency of International Concern on 30 January 2020 by the WHO. As of March 11th, the WHO declared the rapidly spreading coronavirus outbreak a pandemic, acknowledging that the virus will likely spread to all countries in the world.

The objectives of Corona Virus Net are to be the public and professional information resource for coronaviruses and to serve as a network in the exchange of information and news related to coronaviruses. What do you know about the novel Coronavirus that is causing a health emergency?

  Mon, 20 Sep 2021 21:44:10 -0400
  COVID-19 -- Worldwide/Unknown
  A lower dose of the Pfizer-BioNTech coronavirus vaccine -- one-3rd the amount given to adults and teens -- is safe and triggered a robust immune response in children as young as 5 years old, the drug companies announced in a news release Monday morning.
  The finding, eagerly anticipated by many parents and pediatricians, is a crucial step toward the 2-shot coronavirus vaccine regimen becoming available for younger school-aged children, perhaps close to Halloween.

• Assessment of Proinflammatory Cytokines Among Patients with Middle East Respiratory Syndrome Coronavirus Infection Fri, 24 Mar 2023 06:00:00 -0400
  Middle East respiratory syndrome coronavirus (MERS-CoV) is associated with significant morbidity and mortality. This study was performed to assess the proinflammatory cytokines profile among MERS-CoV patients. A total of 46 MERS-CoV-infected patients (27 symptomatic and 19 asymptomatic) were assessed and compared with 52 normal healthy controls for plasma levels of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-17, IL-7, IL-6, interferon (IFN)-α, and IL-15 using a customized luminex kit....
• Laminating Structure for Interlayer Corona Discharge Treatment Toward Ion-Based Nanogenerators Fri, 24 Mar 2023 06:00:00 -0400
  A corona discharge treatment (CDT) is utilized to maximize the performance of triboelectric nanogenerators (TENGs) by injecting extra electrons into the negative tribomaterials. Increased performance of CDT TENGs, however, exhibits rapid degradation due to the electron dissipation by air moisture or thermal emission. To overcome such drawbacks and circumvent such dissipation, the source of charges should be replaced with ionic charges. This study reports a Ag nanowires (NWs)-embedded laminating...
• The spectrum of computed tomography findings in blunt trauma of the subclavian/axillary artery: a pictorial essay Fri, 24 Mar 2023 06:00:00 -0400
  Traumatic injuries of the subclavian and axillary arteries are uncommon but have high morbidity and mortality. In contrast to penetrating injuries, which are often lethal, blunt injuries present a wide and heterogeneous spectrum of imaging findings. If a vessel tear or transsection is a life-threatening circumstance, minor injuries might be overlooked in an emergency setting but could cause or aggravate the functional loss of a limb. The aim of this pictorial essay is to acquaint radiologists...
• Working in corona-designated departments in a fortified underground hospital: Concerns about corona and predictors of job burnout Fri, 24 Mar 2023 06:00:00 -0400
  CONCLUSION: The two groups showed no significant differences in psychological distress nor in burnout. Being a physician, having an intrinsic trait of being overly worried and experiencing psychological distress were significant predictors for job burnout among healthcare workers, regardless of work environment (underground vs. control).
• Identification of novel inhibitors for SARS-CoV-2 as therapeutic options using machine learning-based virtual screening, molecular docking and MD simulation Fri, 24 Mar 2023 06:00:00 -0400
  The new coronavirus SARS-COV-2, which emerged in late 2019 from Wuhan city of China was regarded as causing agent of the COVID-19 pandemic. The primary protease which is also known by various synonymous i.e., main protease, 3-Chymotrypsin-like protease (3CL^(PRO)) has a vital role in the replication of the virus, which can be used as a potential drug target. The current study aimed to identify novel phytochemical therapeutics for 3CL^(PRO) by machine learning-based virtual screening. A total of...

  CONCLUSION: This study confirms the association of economic stressors and mental health during the COVID-19 pandemic and highlights the exacerbating role of subjective risk perception on this association.
• Shortening the sulfur cell cycle by a green approach for bio-production of extracellular metalloid-sulfide nanoparticles Fri, 24 Mar 2023 06:00:00 -0400
  In the present study, a new approach was introduced regarding the extracellular synthesis of selenium sulfide micro/nano-particles using Saccharomyces cerevisiae in different ammonium sulfate supplementation and in the presence of sodium selenosulfate precursors (S(1)) and a blend of selenous acid and sodium sulfite (S(2)). In S(1), only cell supernatant exposed to ammonium sulfate was able to reduce sodium selenosulfate. Whereas, in S(2), cell supernatant in both pre-conditions of with or...

• Outcomes with Endovascular Treatment of Patients with M2 Segment MCA Occlusion in the Late Time Window Thu, 23 Mar 2023 06:00:00 -0400
  CONCLUSIONS: In the late time window, patients with M2 occlusions treated with endovascular thrombectomy achieved better clinical outcomes, similar reperfusion, and lower symptomatic intracranial hemorrhage rates compared with patients with M1 occlusion. These results support the safety and benefit of endovascular thrombectomy in patients with M2 occlusions in the late window.
• A cell-free platform to measure coronavirus membrane fusion Thu, 23 Mar 2023 06:00:00 -0400
  Here we present a protocol to measure coronavirus-mediated membrane fusion, an essential event in coronavirus cell entry. The approach uses nanoluciferase (Nluc) "HiBiT"-tagged corona virus-like particles (VLPs) and Nluc "LgBiT"-containing extracellular vesicles (EVs) as proxies for virus and cell, respectively. VLP-EV membrane fusion allows HiBiT and LgBiT to combine into measurable Nluc, which signifies virus fusion with target cell membranes. We highlight assay utility with methods to assess...
