Avian Adenovirus Group 1 has been discovered in breeder chicks aged 3-7 days, causing inclusion body hepatitis in poultry.
The virus, which reportedly cannot be transmitted to humans, was found in chicken farms in Thailand's central, western and eastern regions by a team of Kasetsart University's veterinary diagnostic unit.
The virus which broke out at six chicken farms in the three regions earlier this year has been contained, said Taweesak Songserm, leader of the university's veterinary unit.
Besides young chickens, the virus can also be found in pigeons, geese, turkeys and partridges, Songserm said.
The disease takes 3-7 days to incubate. The symptoms, including drowsiness and exhaustion, will last for about one week, and become apparent in three weeks, Songserm added.
Besides transmission from hen to chicks via the egg, the disease can also be transmitted between chickens through virus-contaminated food, drink and equipment.
