Novel influenza A (H1N1) is a new flu virus of swine origin that was first detected in Mexico and the United States in March and April, 2009. The first novel H1N1 patient in the United States was confirmed by laboratory testing at CDC on April 15, 2009. The second patient was confirmed on April 17, 2009. It was quickly determined that the virus was spreading from person-to-person. On April 22, CDC activated its Emergency Operations Center to better coordinate the public health response. On April 26, 2009, the United States Government declared a public health emergency.
It’s thought that novel influenza A (H1N1) flu spreads in the same way that regular seasonal influenza viruses spread; mainly through the coughs and sneezes of people who are sick with the virus.
According to the World Health Organization, each year there are an estimated 1 billion cases of influenza, between 3-5 million severe cases and up to 650,000 influenza-related respiratory deaths globally.
The potential "tripledemic" of influenza, SARS-CoV-2 and RSV (respiratory syncytial virus) infection continues to be a concern.
A recent study published in Viruses reviewed the characteristics of neuraminidase with emphasis on the development of NA-based universal influenza vaccines.
According to a scientific brief by the World Health Organization (WHO), there is insufficient information to implement syndromic COVID-19 testing for SARS-CoV-2 transmission prevention across land borders.
The weekly FluView Report mentions that the number of influenza cases seems to be declining in some areas in the United States. However, the overall seasonal influenza activity remains high.
In a new study, researchers reported the first H5N3 infection in a captive Emperor Tamarin.
Fever, cough, sore throat, and general malaise - the cold season is here, and not only corona but also influenza viruses are spreading again at a rapid pace.
Earlier this year, top leadership at the Centers for Disease Control and Prevention began a monumental task: turning the sprawling, labyrinthine organization known for its highly specialized, academically focused scientific research into a sleek, flexible public health response agency primed to serve the American public.
Researchers review potential areas for mRNA vaccine development against pathogenic viruses other than SARS-CoV-2.
Researchers detected a swine influenza A virus (IAV)-infected patient in routine surveillance at the National Influenza Center in Denmark. The detected influenza variant appeared distinct from any variant found previously in Denmark.
The latest WHO report updated up to 30 October 2022 has data categorized by influenza transmission zones, i.e., countries/regions with similar influenza transmission patterns.
Researchers compared cardiac autopsy samples from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive cases with age-matched samples from influenza hemagglutinin 1 neuraminidase 1 (H1N1) cases, non-influenza lymphocytic myocarditis cases, and heart tissue with no inflammation to understand the mechanisms underlying the pathology of the cardiac complications during coronavirus disease 2019 (COVID-19).
Researchers proposed that vaccines targeting the immunosubdominant yet conserved hemagglutinin (HA) stem could trigger broadly neutralizing antibodies (bnAbs) against influenza A viruses.
In a recent study published in the journal Engineering Reports, researchers evaluated the reduction in exposure to airborne viruses in aircraft cabins when mitigation measures such as mask-wearing and leaving the middle seat vacant were adopted to understand strategies to limit the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during air travel.
New research presented this week at ACR Convergence 2022, the American College of Rheumatology's annual meeting, showed that discontinuing methotrexate for one week after seasonal influenza vaccination provided the same seroprotection as a two-week discontinuation period in patients with rheumatoid arthritis.
Influenza infection and hospitalization rates continue to increase at an alarmingly fast and early rate this year.
Researchers examined virus-virus interactions using human lung cells coinfected with two co-circulating respiratory infection-causing viruses, respiratory syncytial virus (RSV) and influenza A virus (IAV).
Respiratory viruses continue to be a leading cause of childhood morbidity and mortality.
Researchers presented an overview of factors influencing emerging infectious diseases. They also highlighted the importance of molecular dynamic (MD) simulations and molecular docking (MDO) analysis for combating these diseases.
A recent study published in the Pulmonary Pharmacology & Therapeutics journal described different inhalation therapeutic agents for treating respiratory viral infections like coronavirus disease 2019 (COVID-19).
