Avian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them.
Can face masks protect against SARS-CoV-2 infection? Faruque Ahmad, MD, recently explored the role of face masks in mitigating the coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2.
A team of researchers at the University of Tokyo in Japan have detected a sarbecovirus, called Rc-o319, which is phylogenetically positioned in the same clade as SARS-CoV-2 in Rhinolophus cornutus bats in Japan.
3D8, a 27-kDa recombinant antibody fragment, was found in autoimmune-prone Murphy Roths Large mice. The single-chain variable fragment (scFv) has the nucleic acid hydrolyzing activity and is shown to degrade DNA or mRNA of viruses in infected cells.
Researchers from the Department of Critical Care Medicine, Sichuan Provincial People's Hospital, Chengdu in China, have explored the possibility of using hydrogen therapy on severely ill COVID-19 patients. The team published their study's findings, titled "Hydrogen: A Potential New Adjuvant Therapy for COVID-19 Patients," in the latest issue of the journal Frontiers in Pharmacology.
United States based researchers have published a report exploring the potential role of Xylitol and Grapefruit seed extract (in the form of a nasal spray) in treating COVID-19.
To efficiently infect human cells, SARS-CoV-2, the virus that causes COVID-19, is able to use a receptor called Neuropilin-1, which is very abundant in many human tissues including the respiratory tract, blood vessels and neurons.
Researchers at Linköping University, Sweden, have developed a unique method to predict influenza epidemics by combining several sources of data.
The COVID-19 pandemic has focused, yet again, intense research interest on coronaviruses, due to the high toll the novel coronavirus SARS-CoV-2 has taken on human life, health, economic well-being, and social activity. A recent paper published on the server Preprints in September 2020 reviews what is known about this viral infection in water life.
Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment.
Small-scale poultry farmers in Vietnam tend to respond to viral outbreaks of highly pathogenic avian influenza (HPAI) by rapidly selling their birds as a way to avoid financial loss, according to a new study by an international team of researchers.
In a recent bioRxiv* preprint paper, researchers from the United States demonstrate the pivotal role the furin cleavage site insertion in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein plays in viral replication and pathogenesis – highlighting, in turn, the need for mutation monitoring when developing therapeutics and vaccines.
In a heated exchange late last month on CNN's State of the Union, host Jake Tapper pressed Adm. Brett Giroir, the Health and Human Services assistant secretary who oversees COVID testing efforts for the Trump administration, on why the government isn't requiring commercial labs to increase testing capacity in order to speed turnaround time.
The virus that causes COVID-19 probably originated in wild bats that live in caves around Wuhan, China, and may have been passed to a second animal species before infecting people, according to the World Health Organization.
As the world grapples with a novel coronavirus pandemic, a new strain of swine flu that can trigger a pandemic has been reported.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing the current pandemic of COVID-19, is the focus of many investigators seeking to find an effective vaccine or therapeutic. Among the potential targets are various protease enzymes suspected of allowing the virus to gain entry to host cells and establish a successful infection.
News-Medical spoke to researchers from the German Primate Center on their research in determining the activation sequence of the SARS-CoV-2 virus.
Researchers have succeeded in detecting anti-avian influenza virus antibody in blood serum within 20 minutes, using a portable analyzer they have developed to conduct rapid on-site bio tests. If a suitable reagent is developed, this technology could be used to detect antibodies against SARS-CoV-2, the causative virus of COVID-19.
The SARS coronavirus 2 (SARS-CoV-2) infects lung cells and is responsible for the COVID-19 pandemic. The viral spike protein mediates entry of the virus into host cells and harbors an unusual activation sequence.
When a person contracts a respiratory viral infection like COVID-19 or influenza, the immune system responds in a myriad of ways to eliminate the virus.
The current COVID-19 outbreak was first reported on 31 December 2019. On 11 March 2020 the World Health Organization (WHO) declared a pandemic.
