Science journalist Tim Vernimmen traveled to Southeast Asia in April to investigate the impact of the controversial study on the avian flu surveillance effort, a journey that landed him right in the middle of the H7N9 conundrum.
This resulted, besides long rambles in the countryside and endless market visits, in some very urgent conversations with some of the key players in the fight against avian flu, including renowned virologist Malik Peiris and epidemiologists like Peter Horby and Arnaud Tarantola.
When Fouchier announced last week that he's planning to do similar reseach on H7N9, the time had come to look back on the trip and try to answer some crucial questions: where did H7N9 go? Is the search effort sufficient? And is it defensible to conduct lab research that might make it more dangerous?
