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.
A recent study published in the United States (U.S.) Centers for Disease Control and Prevention (CDC) journal Emerging Infectious Diseases reported the outbreak of the highly pathogenic hemagglutinin type 5 and neuraminidase type 1 (H5N1) avian influenza virus among New England gray and harbor seals in the United States (U.S.)
In a recent study published in the United States (U.S.) Centers for Disease Control and Prevention (CDC) journal Emerging Infectious Diseases, researchers from Sweden described the detection of the hemagglutinin type 5 and neuraminidase type 1 (H5N1) avian influenza virus in a stranded harbor porpoise, indicating a potential spillover of this highly pathogenic avian influenza virus into cetacean species.
The next pandemic that cascades through the human population could be caused by a new influenza virus strain concocted in animals, against which humans will have little to no immunity.
Scientists have developed mathematical models that analyze the data obtained from an initial wave of the influenza pandemic to predict the dynamics of subsequent waves. Such predictions could be useful for pandemic preparedness.
The United States, the largest importer of wildlife in the world, is not prepared for future spread of animal-borne, or zoonotic, diseases due to gaps among governmental agencies designed to combat these threats, concludes a new analysis by researchers at Harvard Law School and New York University.
Researchers correlate SARS-CoV-2 load and neutralizing capacity of all saliva immunoglobulins isotypes in asymptomatic individuals.
Researchers investigate the sociodemographic factors that contribute to the remission of long COVID.
A study published in PLOS PATHOGENS describes the prevalence and functions of mutations in neuraminidase enzyme of avian H5N1 influenza viruses that are preferentially selected in human H5N1 influenza viruses.
Highly pathogenic avian influenza (HPAI) A(H5N1) is a strain of the avian influenza virus that primarily affects birds, particularly poultry. HPAI A(H5N1) is a highly contagious and deadly virus that can cause severe illness and death in birds, including chickens, ducks, geese, and turkeys.
Researchers performed a systematic review and meta-regression study to determine the breadth and duration of the protective immunity conferred by previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and hybrid immunity.
In a recent article published in the Disease Outbreak News section of the World Health Organization (WHO) website, they reported severe infection from the current H5 clade of avian influenza A virus in a nine-year-old girl inhabiting a rural province of Bolívar in Ecuador.
A recent study published in the journal Scientific Reports examined the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) whole genome data to determine the deletion mutations around the spike protein region associated with increased transmission of the virus and identified an increase in the deletion-prone spike protein regions indicating an evolution strategy for immune escape.
A recent study posted to the medRxiv* preprint server developed a hierarchical modeling method to estimate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant fitness advantage and prevalence.
Researchers used sheep, a ruminant mammal, to obtain polyclonal immunoglobulins (IgGs) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
All poultry and captive birds must be housed in England until further notice, following an increase in the number of detections of avian influenza in wild birds and on commercial premises.
A recent study identified neutralizing antibodies against conserved SARS-CoV-2 epitopes.
Researchers conducted a retrospective analysis to investigate the impact of vaccine-sharing strategies on the heterogenous global distribution of COVID-19 vaccines.
The prevalence of the avian influenza H5N8 virus among birds and its pervasiveness based on geographical locations and time-point.
Researchers explored the genetic variability among the monkeypox virus genomes of Clade IIb lineage B.1 using a phylodynamic and genetic survey to confirm the epidemic cluster in the clade and understand the evolution of the virus.
In a recent study published in the journal JAMA Network Open, researchers in the United States estimated the sociodemographic factors associated with and prevalence of post-acute coronavirus disease 2019 (COVID-19) symptom sequelae (PASC) or long COVID (LCOVID).
