What You Get When You Mix Chickens, China and Climate Change

02/05/2016

Excerpt: "Every few months, it seems, an invasive virus from a distant land attacks the Americas: dengue, chikungunya and, most recently, Zika. But the pathogens that frighten me most are novel strains of avian influenza.

I’d come to see their birthplace. Highly virulent and easily transmissible, these viruses emerge from open-air poultry farms and markets of the kind that stretch across Asia. Thanks to rising demand for chicken and other poultry, they’ve been surfacing at an accelerated clip, causing nearly 150 percent more outbreaks in 2015 than in 2014. And in late 2014, one strain managed to cross the ocean that had previously prevented its spread into the Americas, significantly expanding its reach across the globe.

Novel avian influenza viruses are mongrels, born when the influenza viruses that live harmlessly inside the bodies of wild ducks, geese and other waterfowl mix with those of domesticated animals like the ones at Jiangfeng, especially poultry but also pigs. It’s possible to squelch their emergence. One way is to protect domesticated animals from the excreta of waterfowl, which can spread infection. But no such protections are in effect at markets such as Jiangfeng, which, like the rest of southern China’s booming poultry industry, lies within the East Asian flyway, one of the world’s most important waterbird migration routes."

Six Cases of Bird Flu Reported in China, With One Fatality

01/07/2016

Excerpt: "Local officials in China have reported six new cases of H5N6 avian flu — commonly referred to as bird flu — in the country, though they say the virus is not currently transmittable through human-to-human contact.  Half of the six cases were reported in the southern province of Guangdong, where three individuals fell ill after coming into contact with live poultry or visiting markets where it was sold, reports the South China Morning Post."
