Highly pathogenic avian influenza in Thailand
Summary of two-month nationwide active surveillanceA nationwide active surveillance campaign has been conducted since 1 July 2005. The purpose of this surveillance is to evaluate the present status of highly pathogenic avian influenza after the second wave of outbreaks between 3 July 2004 and 12 April 2005.
As a result of this two-month campaign, 29 new outbreaks have been confirmed in four provinces:
Affected province No. of outbreaks Ayudhaya 1 Chainat 1 Kampaengphet 8 Suphanburi 19 All cases involved either free-range poultry or poultry raised in farms with traditional husbandry practices with poor sanitation and insufficient biosecurity, notably in the 3 outbreaks involving quail.
Affected population No. of outbreaks native poultry 21 quail 3 fighting cocks 2 laying hens 1 laying ducks 1 broilers 1 For effective movement control and farming management, all 76 provinces of Thailand have been grouped into five poultry zones (see table hereafter). All four affected provinces are in the central poultry zone.
