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.

- Role of individual characteristics and national distancing policies for COVID-19 protective behaviour among older adults: a cross-sectional study of 27 European countries Fri, 03 Feb 2023 06:00:00 -0500
CONCLUSIONS: Protective behaviours responded to distancing policies, but our results suggest that people used them voluntarily, especially if they were at health risk.
- Automated model discovery for human brain using Constitutive Artificial Neural Networks Fri, 03 Feb 2023 06:00:00 -0500
The brain is our softest and most vulnerable organ, and understanding its physics is a challenging but significant task. Throughout the past decade, numerous competing models have emerged to characterize its response to mechanical loading. However, selecting the best constitutive model remains a heuristic process that strongly depends on user experience and personal preference. Here we challenge the conventional wisdom to first select a constitutive model and then fit its parameters to data....
- Water-soluble polythiophene-based colorimetry for the quick and accurate detection of SARS-CoV-2 RNA Fri, 03 Feb 2023 06:00:00 -0500
The SARS-CoV-2-related Corona Virus Disease 2019 (COVID-19) epidemic has had a significant negative impact on society and endangered global health. To quickly stop and constrain the pandemic, a SARS-CoV-2 detection technology that is sensitive, quick and reasonably priced is urgently required. The widely used reverse-transcription polymerase chain reaction (RT-PCR) requires complex equipment and a fair amount of time. Reverse transcription-loop-mediated isothermal amplification (RT-LAMP)...
- Modeling the impact of combined use of COVID Alert SA app and vaccination to curb COVID-19 infections in South Africa Fri, 03 Feb 2023 06:00:00 -0500
The unanticipated continued deep-rooted trend of the Severe Acute Respiratory Syndrome Corona-virus-2 the originator pathogen of the COVID-19 persists posing concurrent anxiety globally. More effort is affixed in the scientific arena via continuous investigations in a prolific effort to understand the transmission dynamics and control measures in eradication of the epidemic. Both pharmaceutical and non-pharmaceutical containment measure protocols have been assimilated in this effort. In this...
- Provision of and trust in COVID-19 vaccines information: Perspectives of people who have had COVID-19 Fri, 03 Feb 2023 06:00:00 -0500
CONCLUSION: Different characteristics of people who had COVID-19 and sought information were identified, which is important to offer tailored information. People who had COVID-19 in this study, mainly middle-aged, vaccinated and highly educated, were generally positive about the vaccines information, but overall the reliability and clarity could be improved. This is important for a high vaccination uptake, booster programs and coming pandemics.
- Depression, anxiety and stress after COVID-19 vaccination: A retrospective cross-sectional study among health care providers Fri, 03 Feb 2023 06:00:00 -0500
CONCLUSIONS: To the best of our knowledge, this is the first study that assesses mental health after receiving the COVID-19 vaccine in the middle east. The study concluded that HCPs have low DASS-21 scores and this gives us promising results for the use of the COVID-19 vaccine in future.
- Assessment of commitment to healthy daily habits and diets, preventive measures, and beliefs about natural products utilization during COVID-19 pandemic in certain population in Egypt and Saudi Arabia Fri, 03 Feb 2023 06:00:00 -0500
CONCLUSION: Natural products selected in the present study can be used in combination with the existing clinical standards of care that have the potential to serve as prophylactic agents in populations that are at risk to develop COVID-19 infection.
- Clinical outcomes in COVID-19 among patients with hypertension in the Philippine CORONA Study Fri, 03 Feb 2023 06:00:00 -0500
CONCLUSIONS: Our analysis of nationwide data confirmed previous findings that hypertension is an independent risk factor for worse clinical outcomes among patients hospitalized for COVID-19, with increased odds of in-hospital mortality, respiratory failure, ICU admission, and severe/critical COVID-19. More specific studies should be done to elucidate the impact of hypertension characteristics, such as chronicity, severity, drug therapy, and level of control on these clinical outcomes.
- The impact of Zn doping on CdTe quantum dots-protein corona formation and the subsequent toxicity at the molecular and cellular level Thu, 02 Feb 2023 06:00:00 -0500
Understanding the formation of protein corona (PC) is of vital importance for exploring the toxicity of nanoparticles and promoting their safe applications. In this study, CdTe QDs doping with 0, 1%, 5% and 10% Zn were synthesized using one-pot hydrothermal methods. Afterwards, this study explored and compared the formation of pure and Zn doped-QDs PC as well as the subsequent molecular and cellular toxicity. Result found that Zn doping regulated the toxicity of Cd-QDs by controlling their...
- Deciphering the microheterogeneous repartition effect of environmental matrix on surface-enhanced Raman spectroscopy (SERS) analysis for pollutants in natural waters Thu, 02 Feb 2023 06:00:00 -0500
Although surface-enhanced Raman spectroscopy (SERS) offers a promising technology for sensitive detection of environmental pollutants in natural waters, its performance can be greatly affected by the environmental matrix. The lack of identification of the origin and the underlying mechanism of matrix effect hinders the application of SERS in practical environmental analysis. Herein, with silver nanoparticles (AgNPs) as a solution-based SERS substrate, the matrix effect from environmental waters...
