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 -- China
  Chinese markets linked to some of the earliest Covid-19 cases were illegally selling a range of wildlife from which the coronavirus may have spread, according to a study published less than 2 weeks after U.S. President Joe Biden ordered a deeper probe into the pandemic's genesis.
  Mink, masked palm civets, raccoon dogs, Siberian weasels, hog badgers and Chinese bamboo rats were among 38 animal species sold live at markets in Wuhan from May 2017 to November 2019, researchers said Monday [7

• Environmental dimensions of the protein corona Sat, 12 Jun 2021 06:00:00 -0400
  The adsorption of biomolecules to the surface of engineered nanomaterials, known as corona formation, defines their biological identity by altering their surface properties and transforming the physical, chemical and biological characteristics of the particles. In the first decade since the term protein corona was coined, studies have focused primarily on biomedical applications and human toxicity. The relevance of the environmental dimensions of the protein corona is still emerging. Often...
• Isolation methods commonly used to study the liposomal protein corona suffer from contamination issues Fri, 11 Jun 2021 06:00:00 -0400
  The liposomal protein corona has been the focus of numerous studies, but there is still no consensus regarding its extent and composition. Rather, the literature is full of conflicting reports on the matter. To elucidate whether there could be a methodological explanation for this, we here scrutinize the efficiency of three commonly used liposome isolation methods at isolating stealth liposomes from human plasma. Firstly, we show that size-exclusion chromatography (SEC) in its standard form is...
• The polymeric glyco-linker controls the signal outputs for plasmonic gold nanorod biosensors due to biocorona formation Fri, 11 Jun 2021 06:00:00 -0400
  Gold nanorods (GNRs) are a promising platform for nanoplasmonic biosensing. The localised surface plasmon resonance (LSPR) peak of GNRs is located in the near-infrared optical window and is sensitive to local binding events, enabling label-free detection of biomarkers in complex biological fluids. A key challenge in the development of such sensors is achieving target affinity and selectivity, while both minimizing non-specific binding and maintaining colloidal stability. Herein, we reveal how...
• The ecological dynamics of the coronavirus epidemics during transmission from outside sources when R ₀ is successfully managed below one Fri, 11 Jun 2021 06:00:00 -0400
  Since COVID-19 spread globally in early 2020 and was declared a pandemic by the World Health Organization (WHO) in March, many countries are managing the local epidemics effectively through intervention measures that limit transmission. The challenges of immigration of new infections into regions and asymptomatic infections remain. Standard deterministic compartmental models are inappropriate for sub- or peri-critical epidemics (reproductive number close to or less than one), so individual-based...
• Amphiphilic Triblock Copolymer Prodrug for Tumor-Specific pH/Reduction Dual-Triggered Drug Delivery: Effect of Self-Assembly Behaviors Fri, 11 Jun 2021 06:00:00 -0400
  Diblock copolymer-based prodrugs have been widely designed for tumor treatment after self-assembly; however, premature drug leakage could not be ignored because their hydrophobic prodrug cores were directly exposed to the media. Here, an amphiphilic triblock copolymer prodrug with a hydrophilic PEG block, a pH-sensitive poly(2-(diisopropylamino)ethyl methacrylate) (PDPA) block, and a hydrophobic reduction-cleavable prodrug block was synthesized for tumor-specific pH/reduction dual-triggered drug...
• Corona Virus Disease-19 serology, inflammatory markers, hospitalizations, case finding, and aging Thu, 10 Jun 2021 06:00:00 -0400
  Most deaths from severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection occur in older subjects. We assessed the utility of serum inflammatory markers interleukin-6 (IL-6), C reactive protein (CRP), and ferritin (Roche, Indianapolis, IN), and SARS-CoV-2 immunoglobulin G (IgG), immunoglobulin M (IgM), and neutralizing antibodies (Diazyme, Poway, CA). In controls, non-hospitalized subjects, and hospitalized subjects assessed for SARS-CoV-2 RNA (n = 278), median IgG levels in...
• Role of vitamins and minerals as immunity boosters in COVID-19 Thu, 10 Jun 2021 06:00:00 -0400
  Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) known as coronavirus disease (COVID-19), emerged in Wuhan, China, in December 2019. On March 11, 2020, it was declared a global pandemic. As the world grapples with COVID-19 and the paucity of clinically meaningful therapies, attention has been shifted to modalities that may aid in immune system strengthening. Taking into consideration that the COVID-19 infection strongly affects the immune system via multiple inflammatory responses,...
• Undergraduate nursing students' resilience, challenges, and supports during corona virus pandemic Thu, 10 Jun 2021 06:00:00 -0400
  The coronavirus global pandemic interrupted teaching at Australian universities. Face-to-face teaching was replaced by online delivery. This presented challenges for nursing programmes due to the hands-on teaching requirements and clinical placements. Questions were raised around students' resilience and stress in the face of adversity. This study explored undergraduate nursing students' resilience, challenges experienced, and supports utilized during the pandemic. Convenience sampling recruited...
• POCUS - Thoracic Sonography in Times of Corona: What Sonographing Family Physicians Should Examine Thu, 10 Jun 2021 06:00:00 -0400
  POCUS - Thoracic Sonography in Times of Corona: What Sonographing Family Physicians Should Examine Abstract. When performing chest sonography of patients with symptoms such as respiratory infection, dyspnea and chest pain, the primary goal is to find or exclude significant diagnoses such as pneumothorax, pleural effusion, pulmonary edema, tumors, pulmonary emboli, etc. as the cause of the symptoms. If infection with SARS-CoV-2 is present, COVID-19 pneumonia can be confirmed or excluded as the...
