Welcome to Corona Virus Net

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?

  • PRO/AH/EDR> COVID-19 update (323): Pfizer vaccine in children, vaccine diplomacy, WHO
    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.
    The companies still must

  • Reinfection cases by closely related SARS-CoV-2 lineages in Southern Brazil Sat, 25 Sep 2021 06:00:00 -0400
    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the pandemic that started in late 2019 and still affects people's lives all over the world. Lack of protective immunity after primary infection has been involved with reported reinfection cases by SARS-CoV-2. In this study, we described two cases of reinfection caused by non-VOC (Variants of Concern) strains in southern Brazil, being one patient a healthcare worker. The four samples previously positive for SARS-CoV-2...

  • Imaging Features at the Periphery: Hemodynamics, Pathophysiology, and Effect on LI-RADS Categorization Fri, 24 Sep 2021 06:00:00 -0400
    Liver lesions have different enhancement patterns at dynamic contrast-enhanced imaging. The Liver Imaging Reporting and Data System (LI-RADS) applies the enhancement kinetic of liver observations in its algorithms for imaging-based diagnosis of hepatocellular carcinoma (HCC) in at-risk populations. Therefore, careful analysis of the spatial and temporal features of these enhancement patterns is necessary to increase the accuracy of liver mass characterization. The authors focus on enhancement...
  • Plasma Heating Induced by Tadpole-like Downflows in the Flaring Solar Corona Fri, 24 Sep 2021 06:00:00 -0400
    As one of the most spectacular energy release events in the solar system, solar flares are generally powered by magnetic reconnection in the solar corona. As a result of the re-arrangement of magnetic field topology after the reconnection process, a series of new loop-like magnetic structures are often formed and are known as flare loops. A hot diffuse region, consisting of around 5-10 MK plasma, is also observed above the loops and is called a supra-arcade fan. Often, dark, tadpole-like...
  • Evolution of the Toroidal Flux of CME Flux Ropes during Eruption Fri, 24 Sep 2021 06:00:00 -0400
    Coronal mass ejections (CMEs) are large-scale explosions of the coronal magnetic field. It is believed that magnetic reconnection significantly builds up the core structure of CMEs, a magnetic flux rope, during the eruption. However, the quantitative evolution of the flux rope, particularly its toroidal flux, is still unclear. In this paper, we study the evolution of the toroidal flux of the CME flux rope for four events. The toroidal flux is estimated as the magnetic flux in the footpoint...
  • SARS-CoV-2: an imperative maternal-fetal concern Fri, 24 Sep 2021 06:00:00 -0400
    Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is a newly emerged virus which belongs to Coronaviridae family within the betacoronavirus genus. Previous reports demonstrated that other betacoronaviruses were responsible for adverse outcomes during pregnancy in human. Due to inadequate data, the consequences of a SARS-CoV-2 infection during pregnancy is still a public health concern in the second year of SARS-CoV-2 circulation in human population. Herein, we aimed to review the...
  • Soft gamma rays from low accreting supermassive black holes and connection to energetic neutrinos Fri, 24 Sep 2021 06:00:00 -0400
    The Universe is filled with a diffuse background of MeV gamma-rays and PeV neutrinos, whose origins are unknown. Here, we propose a scenario that can account for both backgrounds simultaneously. Low-luminosity active galactic nuclei have hot accretion flows where thermal electrons naturally emit soft gamma rays via Comptonization of their synchrotron photons. Protons there can be accelerated via turbulence or reconnection, producing high-energy neutrinos via hadronic interactions. We demonstrate...
  • The pattern of health insurance economic resilience in the Covid 19 pandemic shock Fri, 24 Sep 2021 06:00:00 -0400
    OBJECTIVE: Health insurance is based on people's significant risks in receiving health services that they cannot afford alone. Since the outbreak of the corona epidemic, the health insurance system has suffered many economic problems. Designing a model of a health insurance system based on the requirements of a resilient economy can improve the functions of this system in the corona crisis.
  • Epistaxis Requiring Intervention After Swab for SARS-CoV-2 Thu, 23 Sep 2021 06:00:00 -0400
    CONCLUSION: The nasopharyngeal swab for diagnosis of SARS-CoV-2 can lead to life-threatening complications in rare cases. Considering that daily more than 5 million corona tests are being carried out worldwide as part of the current pandemic, complications should not be neglected. It is necessary that the person performing the swab has a detailed understanding of the anatomy involved. Alternative test methods were further assessed with regard to their sensitivity. With regard to the future need...
