On March 25, Chinese authorities seized manufactured pork buns that were found to be made from Zhejiang pigs that had died of the mysterious ailment. The possibly contaminated pork was in the Chinese food supply. By the end of March, at least 20,000 pig carcasses and tens of thousands of ducks and swans had washed upon riverbanks that stretch from the Lake Qinghai area all the way to the East China Sea -- a distance roughly equivalent to the span between Miami and Boston. Nobody knows how many more thousands of birds and pigs have died, but gone uncounted as farmers buried or burned the carcasses to avoid reprimands from authorities.
While environmental clean-up and agricultural authorities scrambled to remove the unsightly corpses and provide the anxious public with less-than-believable explanations for their demise, a seemingly separate human drama was unfolding. On Feb. 19, a man identified by Xinhua, China's state news agency, only as Li, an 87-year old retiree, was hospitalized in Shanghai with severe respiratory distress and pneumonia. On March 4, Li went into severe cardio-respiratory failure and succumbed.
On Feb. 27, a man identified only as Wu, a 27-year-old butcher or meat processor, fell ill with respiratory distress, was hospitalized, and died on March 10. The day Wu succumbed a third individual, a 35-year-old woman identified as Han, was hospitalized in the city of Nanjing, though she came from distant Chuzhou City, in Anhui province, about 300 miles northwest of Shanghai. Han is reportedly in critical condition, in intensive care. To date, no connection between the three individuals has been found.
The elderly Li may have been part of a family cluster of illness, as his 55-year old son died of pneumonia in March, and another 67-year-old son suffered respiratory distress, but has survived.
On March 31 -- Easter in the United States -- China's newly created National Health and Family Planning Commission (which includes the former Ministry of Health) announced that 87-year-old Li, Wu, and Han all were infected with a form of influenza denoted as H7N9 -- a type of flu never previously known to infect human beings. The commission insisted that Li's two sons (one dead, the other a survivor) were not infected with the flu virus -- their ailments were reportedly coincidental, though they occurred at the same time as the elder Li's demise.
So much for the backstory: What is going on?
