Bird flu-infected worker's travel to Scotland raises pandemic risk
One of two bird flu-infected poultry workers in the UK travelled to Scotland while awaiting test results, prompting criticism of the country's containment strategy. Experts have called for workers to self-isolate until swabs are confirmed negative in future. No new cases have been spotted, and health chiefs are confident anyone potentially at risk has already been hunted down. There is no proof human-to-human transmission has occurred yet, but virologists fear it is inevitable the pathogen will eventually overcome this barrier.
