WASHINGTON, (Reuters) – The new virus that has killed as many as 177 people and spread globally is a mongrel that appears to have mixed with another hybrid virus containing swine, bird and human bits, U.S. researchers reported yesterday.
Raul Rabadan and colleagues at Columbia University in New York analyzed the published genetic sequences from the H1N1 virus that has brought the world to the brink of a pandemic.
“The closest relatives to the virus we have found are swine viruses,” Rabadan said in a telephone interview.
“Six segments of the virus are related to swine viruses from North America and the other two from swine viruses isolated in Europe/Asia,” they wrote in the online journal Eurosurveillance.
The U.S. Centers for Disease Control and Prevention said last week after discovering this virus in two U.S. children that it had four virus types — two swine, an avian and a human component.
It may be even more complex than that.
Influenza viruses mutate constantly and they also swap genetic material with one another promiscuously, especially if an animal or person is infected with two strains at once.
Rabadan’s team said this particular strain looked partly like another hybrid, or what scientists call a reassortant, virus.
“The North American ancestors are related to the multiple reassortants, H1N2 and H3N2 swine viruses isolated in North America since 1998,” they wrote.
“In particular, the swine H3N2 isolates from 1998 were a triple reassortment of human, swine and avian origin.”
Scientists can study those genetics to try to track the origin of the new virus. Mexican officials have denied it came from pigs in Mexico and pork producers have been battling rumors it could have come from pig farms there.
Rabadan said the findings did not show the virus came directly from pigs. “We don’t know how long this virus has been in humans,” he said.
Yeah it’s a mongrel, because it was created in a lab, and unleashed on a naieve population, who don’t even know what’s going on. You can fool the people sometime but you can’t fool all the people all of the time, and now we see the light, stand up for your rights.
its your own “good old usa” govt.
your govt in it too, don’t act like what happens in u.s dont affect canada, they are all in it together.
amen -ra is not we govt…we govt here in canda does go sunday and tuesday school on wednesdays…like yuh didnt know dat….we govt dont do notin wrong…we just follow de leada leada….
