The G4 swine flu virus is not a new virus,
REPUBLIKA.CO.ID, JAKARTA – WHO South-East Asia Region (SEARO) Infectious Disease Director Prof. Dr.Tjandra Yoga Aditama said swine flu virus G4 EA H1N1 is not a new virus. According to him, the only way to anticipate it is by supervision.
Previously, the Executive Director of the WHO Health Emergency Program Dr. Michael Ryan also said that the virus flu babi G4 is not a new virus, but a virus under surveillance. The findings were made from years of supervision.
“It has been under surveillance for some time, so it’s not a new virus,” Tjandra said, quoting Dr Michael Ryan in a virtual discussion about the G4 swine flu that was monitored in Jakarta on Friday (10/7).
The virus has been reported by the Chinese government and has been under surveillance since 2011 and there have been several previous publications about the virus. The team of researchers from China had previously examined the influenza virus found in pigs in the period 2011-2018, found a variant of Genotype 4 (G4) EA H1N1.
At the end of June 2020, a study published by the journal Proceedings of the National Academy of Sciences discusses new strains or strains of H1N1 swine flu. The flu virus had previously circulated in pig populations in China with the most common variant of the H1N1 EA flu virus found was strain or strain Genotype 1, but the strain mutated until Genotype 4 appeared.
Based on reports from research the G4 virus can attach to receptors that are similar to humans in the lining of the respiratory tract and attack the upper part of the airway which can then travel to the lungs.
According to Tjandra, G4 and other types of swine flu and bird flu will continue to evolve. “So for that the only way is to be monitored continuously, not only whether or not there is a monitor, but also monitored the possibility of a risk of a pandemic,” he said.
