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.
Invariably, vaccination programs in high-income countries (HICs) are in a much better position due to their ability to secure a greater number of vaccines from multiple companies. On the contrary, lower-income countries have failed to obtain a sufficient number of vaccines.
Though the U.S. and South Korea recorded their first official COVID-19 case on the same day, January 20, 2020, there were notable differences in how each country would ultimately address what has become the world's most severe pandemic since 1918.
A plethora of earlier studies has reported on the differences between the sexes in susceptibility to the currently circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as its severity. A new preprint research paper posted to the bioRxiv* server extends this to the placenta in pregnancy.
Humans are creating or exacerbating the environmental conditions that could lead to further pandemics, new University of Sydney research finds.
Missourians have driven hours to find vaccines in rural counties — at least those with cars and the time. Tens of thousands of doses are waiting to be distributed, slowly being rolled out in a federal long-term care program.
A team of researchers led by Sander Herfst from Erasmus University Medical Center in The Netherlands suggests severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could spread through the air at a one-meter distance and cause infection in a new ferret model study.
Ask Eric Weaver about pandemics, and he's quick to remind you of a fact that illustrates the fleeting nature of human memory and the proximal nature of human attention: The first pandemic of the 21st century struck not in 2019, but 2009.
A novel computer algorithm that could create a broadly reactive influenza vaccine for swine flu also offers a path toward a pan-influenza vaccine and possibly a pan-coronavirus vaccine as well, according to a new paper published in Nature Communications.
While the vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are administered, and extensive research is conducted for targeted therapeutics to control the COVID-19 (coronavirus disease 2019), it is equally crucial to develop more novel, broad-spectrum antiviral compounds.
Researchers in the United States and Finland have used tissues from people who died from coronavirus disease 2019 (COVID-19) to generate detailed cellular maps of the pathogenetic processes that occur within affected organs during severe disease.
Now, researchers at the University of Silesia in Katowice and the Poznan University of Medical Sciences in Poland recommend measures to prevent future zoonotic outbreaks. They emphasized the importance of viral surveillance and research on new viral strains as primary strategies to combat these infections.
The World Health Organization greenlighted emergency use of AstraZeneca and Oxford's covid-19 vaccine this month, following in the steps of the United Kingdom, the European Union and others, who are already injecting it as quickly as possible into the masses.
So far, based on clinical data, patients with cystic fibrosis (CF) don't appear to be especially susceptible to COVID-19, and when they do get infected, they don't seem to get sicker. But Ruobing (Ruby) Wang, MD, a physician-scientist in the Division of Pulmonary Medicine at Boston Children's Hospital, cares for patients with CF and thinks there is more to the story.
Doctors say a woman in Michigan contracted covid-19 and died last fall two months after receiving a tainted double-lung transplant from a donor who turned out to harbor the virus that causes the disease — despite showing no signs of illness and initially testing negative.
For a decade, Jennifer Crow has taken care of her elderly parents, who have multiple sclerosis. After her father had a stroke in December, the family got serious in its conversations with a retirement community — and learned that one service it offered was covid-19 vaccination.
Researchers report on a Chicken-derived antibody against SARS-CoV-2, offering preliminary data on a potential therapeutic for COVID-19 warranting further research.
A child's first influenza infection shapes their immunity to future airborne flu viruses-;including emerging pandemic strains.
Policymakers at all levels of government are racing to vaccinate hundreds of millions of people to save lives and blunt the deadly COVID-19 pandemic.
An international team of researchers has conducted a study suggesting that individual variation across different strains of betacoronaviruses can alter their stability and pathogenicity profiles.
Face masks mandates have led people to spend less time at home, but whether this has exposed Americans to more risk is still a question, according to a new study published Thursday in Scientific Reports.
