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.
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.
Today, the National Institutes of Health will launch a new website with important educational resources for Coronavirus workers dealing with the spread of COVID-19.
When the federal government decided to investigate the threat viruses in animals posed to humans, Dennis Carroll helped lead the charge.
In the Federal State of Brandenburg, a case of highly pathogenic avian influenza (often referred to as bird flu) was found in a wild goose, caused by a virus of the H5N8 subtype.
The Hong Kong Polytechnic University today announced the development of the world's most comprehensive automated multiplex diagnostic system (the System) which includes a fully automated machine and a multiplex full-screening panel for the point-of-care genetic testing of respiratory infectious disease including the 2019-nCoV.
China has reported an outbreak of the H5N1 bird flu in Hunan, which borders the province of Hubei, the epicenter of the novel coronavirus outbreak.
A new coronavirus virus, likely first transmitted to people from animals at a market in the Chinese city of Wuhan, is making international headlines as disease detectives work to uncover what it is, how it's transmitted, and how deadly the virus actually is.
Scientists have identified the virus likely to have caused a pneumonia-like illness that has caused an outbreak in Wuhan, China.
