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.
Researchers in the United States and India have presented the first known evidence that the rollout of coronavirus disease 2019 (COVID-19) vaccination is restricting the evolutionary and immune escape pathways accessible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Renowned evolutionary researcher, Jesse Bloom from the Fred Hutchinson Cancer Research Center, has conducted a phylogenetic analysis suggesting that the early severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequences that were obtained from the Huanan Seafood Market in Wuhan, China, are not fully representative of the viruses circulating in the city at the time of the coronavirus disease 2019 (COVID-19) outbreak.
The avian influenza, an acute viral infectious disease that occurs in poultry such as chickens, ducks, and migratory birds, has been reported to be transmittable to humans.
The number of COVID-19 variants is growing rapidly, so much that the scale and scope of mutation may pose a threat to the continuing successful use of the current vaccines and therapies.
As the coronavirus disease (COVID-19) pandemic continues to spread and wreak havoc globally, another health threat emerged in China. The country has reported its first confirmed case of the rare H10N3 bird flu in a patient admitted to the hospital in April 2021 in Zhenjiang, China.
A recent article published in the journal Frontiers in Tropical Diseases assessed the threat of emerging zoonotic and vector-borne tropical diseases.
International organizations have come together to launch a new One Health High-Level Expert Panel to improve understanding of how diseases with the potential to trigger pandemics, emerge and spread.
The lack of new or repurposed drugs to treat patients with severe or critical COVID-19 has been one of the biggest hurdles to reducing mortality rates in the ongoing pandemic caused by SARS-CoV-2. A new study describes the potential for the use of the plant molecule isorhamnetin in the management of this virus.
Researchers have analyzed this evolution of the virus based on evolutionary ecology theory. Using the virus genomes available in the Global Initiative on Sharing Avian Influenza Data (GISAID) database, the researchers focused their inquiry on mutations in the receptor-binding domain (RBD) on the spike protein of SARS-CoV-2.
In this News-Medical interview, we spoke to Professor Diana Bell about the illegal wildlife trade and how we could prevent future pandemics by stopping it.
Researchers in Japan have estimated that the B.1.1.7 strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that recently emerged in England is 40% more transmissible than strains previously circulating in the country.
Researchers in the United States have computed genome-wide covariation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to investigate interactions that could be of considerable importance in the prevention, diagnosis, and treatment of coronavirus disease 2019 (COVID-19).
Researchers at the Polish Academy of Sciences in Warsaw have identified a substrain of the recently emerged B.1.1.7 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that may confer resistance to antibody neutralization.
Researchers at the University of Michigan in the United States have cautioned against only using within-host minor genetic variations to resolve the genomic epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).
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.
