The University of Hong Kong cannot move forward with a computer system to track future human-to-human transmission of bird flu because of "constraints" in collecting data from the mainland, a professor involved in the project says.
Lai Poh-chin, associate professor of geography, said the mainland was not supplying the necessary information about current cases, such as location and details of symptomatic people.
"We've had limitations in accessing the data since March," Dr Lai said.
She is hoping to use the department's geographic information system, which allows for the study of data using maps, to monitor the disease in Hong Kong and on the mainland. The same system was used to identify "high-risk areas" during the Sars epidemic in 2003.
"We can use the system to do predictions such as to identify high-risk areas," she said, adding that her department would work with the Centre for Health Protection in the event of an outbreak.
Legislator Kwok Ka-ki, chairman of the health services panel, said it was not surprising the team was unable to obtain sensitive data from the mainland.
Hong Kong health authorities yesterday expressed concern over a previously unreported H5N1 case in Beijing in November 2003.
Last week, the New England Journal of Medicine published a letter by mainland doctors about a Beijing man who was initially thought to have Sars but was later found to have died from bird flu.
That timing appears to indicate the current H5N1 outbreak in Asian poultry, thought to have begun in South Korea in December 2003, in fact started earlier.
