Viruses originating from birds and animals are known as zoonotic viruses. When these viruses are transmitted to humans through direct or indirect contact with infected populations, they cause a zoonotic spillover. Approximately 70% of infectious diseases over the last three decades are zoonotic. Because no immediate diagnosis or effective cure is available for the new

When a virus infects an individual, a complex human immune response is initiated to limit the effects of the viral invasion. One of the several different immune responses that can arise following a viral infection includes the generation of the pleiotropic cytokine interferon (IFN), which acts as a link between the innate and adaptive immune

Since the start of the coronavirus pandemic, thousands of nasopharyngeal swabs have been taken in Austria – millions worldwide. Their correct performance is essential for diagnosing and challenging Covid-19. To assist the correct collection of nasopharyngeal material, a systematic anatomical study conducted at MedUni Vienna specifies guidelines and landmarks and evaluates the danger for the

A retracted study on the safety of blood pressure medications in patients with COVID-19 continues to be cited nearly a year later, new research shows. The study in question, published on May 1, 2020 in the New England Journal of Medicine (NEJM), showed no increased risk for in-hospital death with the use of angiotensin-converting-enzyme (ACE) inhibitors

The World Health Organization (WHO) and the United States Centers for Disease Control and Prevention (CDC) have recognized airborne transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is a highly infectious ribonucleic acid (RNA) virus that was first reported in Wuhan, China in December 2019. Owing to the rapid outbreak of SARS-CoV-2

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the virus responsible for the coronavirus disease 2019 (COVID-19), originally emerged in December 2019 in Wuhan, China, and continues to spread worldwide. The transmission and deadly effects of COVID-19 have been significantly more considerable in densely populated regions such as Hong Kong and India. Urban

New drugs have also been urgently sought to mitigate

Researchers have just established a structural basis for two spike glycoprotein epitopes of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are restricted to human leukocyte antigen (HLA) A2 molecules. More specifically, they are involved in the presentation of antigenic peptides to specific T lymphocytes and recognized by public and private T cell receptors.

Florida’s coronavirus cases jumped 50% this week, the state Health Department reported Friday, continuing a six-week surge that has seen it responsible for 1 in 5 new infections nationally, becoming the outbreak’s epicenter. The release came shortly after Gov. Ron DeSantis barred school districts from requiring students to wear masks when classes resume next month.

As the development of the COVID-19 pandemic to date has shown: aerosols contribute significantly to the occurrence of infection – and combating them can significantly reduce a resurgence of infection levels.
