KATHMANDU, June 28: Crows have been identified as a major factor behind the spread of bird flu across the Kathmandu Valley, according to the Department of Livestock Services.
Director General Dr Umesh Dahal said the virus has spread widely after being detected in crows, which can carry the infection from one location to another. While outbreaks in poultry can be contained, controlling the disease in wild crows is not feasible, he said, adding that crows have transmitted the virus to several areas, including the Central Zoo.
According to Dr Dahal, infected crows can remain contagious for up to 21 days. Dead crows and their droppings can also contribute to the spread of the virus.
Detecting bird flu
Bird flu cases have now been reported in all three districts of the Kathmandu Valley. Nationwide, the disease has been detected at 100 locations across 11 districts.
Dr Dahal said outbreaks in most parts of the Valley have been brought under control, except in Kirtipur and Kageshwori Manohara.
The department has established a bird flu control unit under the leadership of its deputy director general and is carrying out containment measures in coordination with federal, provincial and local authorities in affected areas.
