The Swine flu in China: G4 EA H1N1

..

Swine Influenza is the H1N1 (SIV H1N1) virus. The 2009 H1N1 strain that circulated worldwide in humans is estimated to have caused 12,469 deaths in the U.S. and as many as 575,400 globally.

The swine flu in China is G4 EA H1N1.

It has not arrived in Malaysia.

Pigs are routinely catching variations of the flu and mostly it’s not a big deal, because the viruses usually don’t spread to people. But that’s not the case with the most-common strain infecting pigs in China since 2016, dubbed the G4 EA H1N1 virus. In past years it jumped the species barrier to infect possibly dozens of humans, according to so-called serosurveys that look for the presence of antibodies in a person’s blood, which indicates prior exposure to the virus. New research published June 29 in the Proceedings of the National Academy of Sciences showed the virus can replicate in cells lining the human airway, and can be efficiently transmitted among ferrets, an animal used to study flu viruses. Those features led that research team to declare that it “possesses all of the essential hallmarks of a candidate pandemic virus” and poses “a serious threat to human health.”

 …G4 EA H1N1 has been closely watched by scientists in China and around the world. Anthony Fauci, director of the National Institute for Allergy and Infectious Diseases in the U.S., said it’s not an immediate threat, but bears watching.

G4 EA H1N1 is a Eurasian, avian-like virus with genetic material from the 2009 H1N1 pandemic strain, dubbed “swine flu” because of genetic similarities with viruses known to circulate in pigs. That strain circulated worldwide in humans and is estimated to have caused 12,469 deaths in the U.S. and as many as 575,400 globally. (Unusually for a flu virus, the vast majority of fatalities were under 65 years old.) People then passed the virus back to swine, which are considered to be mixing vessels for influenza viruses. Scientists believe G4 EA H1N1 is the result of the H1N1 flu virus mixing with one or more other influenza strains circulating in hogs.

Swine Influenza H1N1 (SIV H1N1) virus, or more commonly known as swine flu, was found in some samples of commercial livestock and wild boars in Malaysia recently, stated the Department of Veterinary Services (DVS).

However, Malaysia’s strain of H1N1 is different and carries little risk of transmission to humans.

This comes hot on the heels of a report that there is another possibly zoonotic influenza strain in China that can lead to another pandemic.

This zoonotic strain in China is called the G4 EA H1N1, which the pigs here in Malaysia have tested negative for.

Malaysia tests for three different strains descended from the H1N1 swine flu under our national surveillance programme, namely the SIV H1N1, H1N1pdm09, and the G4 EA H1N1.

Only some samples tested positive for SIV H1N1, which does not transmit to humans. The pigs also did not show any symptoms of diseases or risk of infection.

If you’re still worried about the G4 EA H1N1, the Agriculture and Food Industries Ministry has already taken various steps at the country’s entry points to check for signs of the disease with the help of the DVS as well as the Malaysia Quarantine and Inspection Services (Maqis).

The import of pork and swine products are already prohibited from high-risk countries, and there are continuous monitoring efforts on the country’s borders on the import of such items, as well as raising awareness about the risks of disease.
