If you've read the recent cases coming out of Indonesia, you might have noticed a reoccurring theme - people contracting H5N1 while neighborhood poultry all test negative.
Finally someones decided this merits a closer look.
"Indonesia's National Avian Influenza Committee says in the last three to four months there have been four cases where poultry in the victim's neighbourhoods tested negative for the virus.
It says the number is significant enough for investigations to be stepped up to gain a more accurate explanation.
Last year, 20 per cent of confirmed cases in 2006 were inconclusive, meaning there was no direct contact with poultry. This year the figure has increased to 30 per cent."
