H2n1 influenza virus

Study timeline and phylogenetic analysis of strains used in study. (A) Groups of three-week-old swine (n=5/group) were immunized with Ad-swH3-Epi, FluSure XP, or DPBS as a negative control group at D0 and boosted at D21. Blood samples were collected every 7 days for the first month, then every 30 days for the subsequent 5 months for a total duration study of 6 months. Six months after the initial immunization all pigs were subjected to challenge with a divergent Cluster IV(A) IAV-S isolate, A/swine/Wyoming/A01444562/2013. Nasal swabs were taken every other day after challenge, then at 5 days post infection pigs were humanely bled, euthanized, and samples were taken for analysis.

H1N1 In 2009, H1N1 was spreading fast around the world, so the World Health Organization called it a pandemic. Since then, people have continued to get sick from swine flu, but not as many. While swine flu isn't as scary as it seemed a few years ago, it's still important to protect yourself from getting it. Like seasonal How Do You Catch It? The same way as the seasonal People who have it can spread it one day before they have any symptoms and as many as 7 days after they get sick. Kids can be contagious for as long as 10 days. Despite the name, you can't catch swine flu from eating bacon, ham, or any other pork product. Swine Flu Symptoms These, too, are pretty much the same as seasonal flu. They can include: • • Fever • • Stuffy or • Body aches • • Chills • Like the regular flu, swine flu can lead to more serious problems including Are There Tests for Swine Flu? Yes. Without one it's hard to tell whether you have swine flu or seasonal flu, because most symptoms are the same. If you have swine flu, you may be more likely to feel sick and your To test for swine flu, your doctor runs a swab -- a bigger version of the ones in your bathroom -- up the inside of your nose around the back of your throat. But the test isn’t as common or widespread as those for regular flu. So the only people who really need to be tested are those in the hospital or those at high risk for life-threatening problems from swine flu, such as: • Children under 5 years old • People 65 or older • Childre...

A team led by Eric Weaver, associate professor of biological sciences, has developed a robust vaccine against a strain of swine influenza. Framed by a model of nucleic acid proteins is (from left) Weaver; Matt Pekarek, a graduate student in the Weaver Lab; Cedric Wooledge, a technician with the Institutional Animal Care Program; David Steffen, with the Nebraska Veterinary Diagnostic Center; and Nicholas Jeanjaquet and Erika Petro-Turnquist, both doctoral students in the Weaver Lab.

A successful long-term experiment with live hogs indicates Nebraska scientists may be another step closer to achieving a safe, long-lasting and potentially universal vaccine against swineflu. The results are not only important to the pork industry, they hold significant implications for human health. That’s because pigs act as “mixing vessels,” where various swine and bird influenza strains can reconfigure and become transmissible to humans. In fact, the 2009 swine flu pandemic, involving a variant of the H1N1 strain, first emerged in swine before infecting about a fourth of the global population in its first year, causing nearly 12,500 deaths in the United States and perhaps as many as 575,000 worldwide, according to the Centers for Disease Control andPrevention. “Considering the significant role swine play in the evolution and transmission of potential pandemic strains of influenz...

Swine flu (H1N1) is a type of viral infection. It’s called swine flu because it resembles a respiratory infection that pigs can get. In 2009, an H1N1 pandemic infected millions of people worldwide. Today, you can prevent H1N1 with an annual flu shot. You can treat it with rest, fluids and antiviral medications. Overview What is swine flu (H1N1)? Swine flu (H1N1) is an infection that a type of Are swine flu (H1N1) and Spanish flu the same thing? In 1918, a flu pandemic from a strain of H1N1 infected 500 million people around the world. It was known as the Where did the 2009 swine flu (H1N1) pandemic start? In April 2009, researchers discovered a new strain of H1N1. They detected it in the United States first. The virus spread quickly across the U.S. and around the world. It spread quickly because it was a new type of flu virus. Young people weren’t The new strain infected millions of people worldwide. At least 150,000 people worldwide died. Eighty percent of those who died were younger than 65. When did the swine flu (H1N1) pandemic end? The World Health Organization (WHO) said the pandemic was over in August 2010. However, people can still get and spread H1N1. H1N1 is one of the seasonal flu viruses. It can cause illness, hospitalization and death. Symptoms and Causes What causes swine flu (H1N1)? A virus causes swine flu (H1N1). It spreads from person to person. When a person You can’t get H1N1 by eating pork. Is swine flu (H1N1) contagious? Yes. Swine flu (H1N1) is conta...
