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?

  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.

• Hybrid PSO-SVM algorithm for Covid-19 screening and quantification Mon, 17 Jan 2022 06:00:00 -0500
  Corona Virus Disease (COVID) 19 has shaken the earth at its root and the devastation has increased the diagnostic burden of radiologists by large. At this crucial juncture, Artificial Intelligence (AI) will go a long way in decreasing the workload of physicians working in the outbreak zone, aiding them to accurately diagnose the new disease. In this work, a hybrid Particle Swarm Optimization-Support Vector Machine based AI algorithm is deployed to analyze the Computed Tomography images...
• Small businesses and their challenges during COVID-19 pandemic in developing countries: in the case of Ethiopia Mon, 17 Jan 2022 06:00:00 -0500
  Mainly this study was aimed at demonstrating the challenges of small businesses during the corona virus pandemic in developing countries, specifically in Ethiopia. Methodologically, the study deployed secondary data analysis following a descriptive research design. Furthermore, this study was conducted through both qualitative and quantitative research approaches. The secondary data analysis result shows that many small and large businesses are suffering challenges and this unprecedented...
• A cross-sectional study of gastrointestinal manifestations in COVID-19 Egyptian patients Mon, 17 Jan 2022 06:00:00 -0500
  CONCLUSIONS: GI symptoms are prevalent among COVID-19 patients, the most common which were vomiting and diarrhea and were associated with COVID-19 severity.

• NuSTAR observations of a repeatedly microflaring active region Mon, 17 Jan 2022 06:00:00 -0500
  We investigate the spatial, temporal, and spectral properties of 10 microflares from AR12721 on 2018 September 9 and 10 observed in X-rays using the Nuclear Spectroscopic Telescope ARray and the Solar Dynamic Observatory's Atmospheric Imaging Assembly and Helioseismic and Magnetic Imager. We find GOES sub-A class equivalent microflare energies of 10^(26)-10^(28) erg reaching temperatures up to 10 MK with consistent quiescent or hot active region (AR) core plasma temperatures of 3-4 MK. One...
• FOXSI-2 Solar Microflares. II. Hard X-ray Imaging Spectroscopy and Flare Energetics Mon, 17 Jan 2022 06:00:00 -0500
  We study the nature of energy release and transfer for two sub-A class solar microflares observed during the second Focusing Optics X-ray Solar Imager (FOXSI-2) sounding rocket flight on 2014 December 11. FOXSI is the first solar-dedicated instrument to utilize focusing optics to image the Sun in the hard X-ray (HXR) regime, sensitive to energies of 4-20 keV. Through spectral analysis of the microflares using an optically thin isothermal plasma model, we find evidence for plasma heated to ~10 MK...
• Periodicities in an active region correlated with Type III radio bursts observed by Parker Solar Probe Mon, 17 Jan 2022 06:00:00 -0500
  CONTEXT: Periodicities have frequently been reported across many wavelengths in the solar corona. Correlated periods of ~5 min, comparable to solar p-modes, are suggestive of coupling between the photosphere and the corona.
