Indonesia overtook Thailand recently as the second worst-affected country in the world, after
Vietnam, in terms of the number of people killed by1 H5N1 bird flu.. Thirty people are now
confirmed as having died in Indonesia.

2. The virus has been found in poultry in the majority of Indonesia's thirty three provinces.
Worryingly, the latest cluster of deaths was on the island of Sumatra, not Java where all previous
confirmed fatalities had been 3. recorded. All the Sumatran victims were reported to have been in
close 4. proximity  to sick poultry.

The United Nations Food and Agriculture Organisation this week 5. warned Indonesia that they it was
failing to combat the spread of the disease, both in terms of controlling animal 6. infections and
failing to increase public awareness. The Indonesian authorities say they are watching the Sumatra
cluster carefully but there's no evidence that the virus was 7. passed  from human to human.
