“The World Is Watching the U.S. Deal With Bird Flu, and It’s Scary”
By Tulio de Oliveira
“As a virus scientist in South Africa, I’ve been watching with dread as H5N1 bird flu spreads among animals in the United States. The pathogen poses a serious pandemic threat and has been detected in over 500 dairy herds in 15 states — which is probably an undercount. And yet, the U.S. response appears inadequate and slow, with too few genomic sequences of H5N1 cases in farm animals made publicly available for scientific review.
Failure to control H5N1 among American livestock could have global consequences, and this demands urgent attention. The United States has done little to reassure the world that it has the outbreak contained.
The recent infection of a pig at a farm in Oregon is especially concerning as pigs are known to be “mixing bowls” for influenza viruses. Pigs can be infected by both avian and human influenza viruses, creating a risk for the viruses to exchange genetic material and potentially speed up adaptation for human transmission. The H1N1 pandemic in 2009 was created and spread initially by pigs.”

“The world cannot afford to gamble with this virus, letting it spread in animals and hoping it never sparks a serious outbreak — or crossing our fingers that its effects won’t be serious in people. Time will tell. I hope we are not watching the start of a new pandemic unfold, with both the American and the international communities burying our heads in the sand rather than confronting potential danger.”
