Influenza A is a type of virus that causes the flu. Most people who have flu are infected with the influenza type A virus. Symptoms of influenza A infection include fever, chills, muscle pains, coughing and a sore throat.

Characteristics of the New H1N1 Flu Strain Some people also experience gastrointestinal symptoms, such as nausea or diarrhea. This is thought to be one of the ways it differs from seasonal flus. Most people experience a mild illness for several days and then recover.

The 2009 swine flu outbreak did not originate in China - the virus started in Mexico in April 2009. ing to the WHO, between 105,000 and 395,000 people are thought to have died from it (here) (here ).

Current subtypes of influenza A viruses that routinely circulate in people include A(H1N1) and A(H3N2).

Furthermore, the sequences suggest that viruses with a similar genetic composition to the 2009 pandemic virus have been circulating in pigs in central-west Mexico for more than a decade. Thus, this region is the most likely source of the virus that started the 2009 pandemic.

The HA glycoprotein of influenza virus is an integral membrane protein (type I transmembrane glycoprotein) that has a cylindrical shape with approximate dimensions of 135 Å (length) × 35–70 Å (radius) forming spikes that project externally.

Swine-origin (or swine-lineage) influenza virus (SIV) infections also occur in poultry and humans, but interspecies transmission is considered a rare event. There are sporadic reports of human infections with swine influenza viruses, mainly in people who had direct contact with infected pigs.

H1N1 flu is a subtype of influenza A. Flu, also called influenza, is a viral infection of the nose, throat and lungs, which are part of the respiratory system.

The H1N1 flu, sometimes called swine flu, is a type of influenza A virus. During the 2009-10 flu season, a new H1N1 virus began causing illness in humans. It was often called swine flu and was a new combination of influenza viruses that infect pigs, birds and humans.

Current subtypes of influenza A viruses that routinely circulate in people include A(H1N1) and A(H3N2).

The protein has a calculated MW of 60.3 kDa. The protein migrates as 66-100 kDa under reducing (R) condition (SDS-PAGE).

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.
