DieCorona pandemic is not yet over, the security measures to curb the dissemination to the public life.
And now this message from China: scientists have been in pig fattening, a new influenza virus operated discovered, which spreads among the animals.
their findings, the researchers of the Chinese Academy of Sciences, shared in the scientific magazine ‘PNAS’.
Therefore, these pathogens don’t make the animals sick, it would have also, similar to the swine flu in 2009, “pandemic Potential”.
mixed viruses in pigs
influenza viruses are changing rapidly. In this country that makes the annual flu epidemics is noticeable, in which slightly modified versions of the virus are rife.
There is, however, that new fatal viruses.
This often happens with pigs, because can infect these animals at the same time with different influenza viruses mammalian, human and avian – influenza strains to exchange their genes.
Thus, in the case of a mixed virus, spreading since 2013, in pig farms in China. As the researchers report, had become this Virus is now the dominant variant.
In the investigation of the new influenza variant G4, the scientists were noisy. In the case of this Virus it is in fact a mixture of three lineages:
- one that is similar to strains found in European and Asian birds,
- the H1N1 strain that caused the pandemic in 2009,
- a North American H1N1, the genes of influenza viruses of birds, humans and pigs contains
Through this combination of G4 can animals, not only, but also cells of the human respiratory tract, infect. Between ferrets, considered a good model for influenza spreads, it spread slightly.
workers have already antibodies against the new Virus on
The scientist have already been able to demonstrate antibodies against the G4 Virus in the workers of pig farms – each tenth Person.
A slight sigh of Relief there should be but probably. Because so far only two cases have been documented where the Virus has triggered in people with a serious illness – a 46-Year-old died of it.
As the scientists hold on to, not such cases were far more dangerous, as the Virus has not yet been passed from human to human.
the Virus should continue to be observed
experts such as flu-researcher Martha Nelson of the American National Insitutes of Health, therefore, slight all-clear.
The researcher feels that it is appropriate to watch G4 more carefully, you will see, however, currently there is no direct evidence that this can trigger a new, deadly wave of Influenza.
Because it would have to spread easily from person to person and a severe course of the disease trigger.
Nelson noted in a scientific article, however, is that influenza can change virus also surprising.
in addition, would be due to the Corona pandemic, “the danger is that we neglect to Influenza and other threats.”
production of flu vaccinations are Routine
if there is indeed a new flu virus spread, the infected people, worldwide, registration is obligatory.
The world health organization (WHO) and the production of a suitable vaccine to be launched would be informed.
This production is likely to be also significantly simpler than that of a matching By means of counter-Covid-19. Because flu vaccinations are now Routine.
