TAIPEI:
Three poultry farm workers have been
tested positive for the H5N2 avian influenza strain but none have displayed flu
symptoms, Taiwan's disease control authorities said.
They
were among 141 people working at five poultry farms where the avian flu was
discovered.
Tens of
thousands of chickens in the farms have been culled since the outbreak of H5N2
in the past few months.
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 in farms
in central Taiwan.
The flu
has so far affected chicken farms in Changhua, Tainan and Nantou.
