Every time a virus jumps from animals into people there’s a shudder of alarm.
So-called zoonotic illnesses have resulted in pandemics previously, most lately after all COVID-19.
That’s why the UK Health Security Agency is attempting to work out how somebody in Yorkshire has been contaminated with a pressure of flu so just like a virus circulating in pigs within the UK.
We do not know a lot in regards to the particular person. But we do know they solely had gentle signs and absolutely recovered.
And they did not work with pigs. That’s the puzzle.
Does it imply that the virus is circulating in folks, undetected till now?
Health authorities are tracing contacts of the contaminated particular person and try to establish the supply.
Flu usually crosses the species barrier by infecting folks in shut contact with animals.
That’s why individuals who work with chickens are checked for chicken flu, which is brought on by one other pressure of the virus.
But even when there’s a human case of an animal virus that is often the top of the story. The virus is not handed on as a result of it is not properly sufficient tailored to human cells to unfold from individual to individual.
Officially there isn’t any proof of human transmission of the brand new swine flu virus.
But it is arduous to see another clarification for the time being.
That does not imply we’re on the verge of a brand new pandemic. The pressure might disappear as shortly because it emerged.
But scientists will need to perceive extra in regards to the virus to gauge how transmissible it’s – and likewise to make certain it is no more of a threat to people who find themselves weak, both due to age or underlying well being situations.
