Taiwanese poultry farm workers have tested positive for the H5N2 avian flu strain despite not displaying flu symptoms, the country's disease control authorities have revealed.
The workers were among 141 people working at five poultry farms where the avian flu was discovered.
In the past few months since the outbreak of H5N2, tens of thousands of chickens from the farms were culled. Avian Influenza has so far affected poultry farms in Changhua, Tainan and Nantou.
Medical experts believe the test results may well be a cross-reactivity since all the three persons had flu jabs last year, Xinhua news agency reported. Cases of humans who tested positive for H5N2 while showing no health disorders were previously reported in South Africa and Japan between 1993 to 1995.
Taiwan authorities confirmed the outbreak of H5N2 following sporadic reports on farms in central Taiwan.
