A Vietnamese man has died of bird flu, taking Asia's death toll
to 19, and a Cambodian woman who died last week in a Vietnamese
hospital could be the first victim from that neighboring country,
officials said on Monday.
However, a report from the World Health Organization (WHO) at
the weekend showed the H5N1 virus was not spreading from person
to person, suggesting it was not yet mutating into forms that
could turn it into a global epidemic for humans.
The latest victim was a 27-year-old man from Vietnam's
southern Binh Phuoc province, a medical official said.
A 23 year-old man from Vietnam's Central Highlands has tested
positive for the H5N1 strain and was being treated, the official
from the Pasteur Institute in Ho Chi Minh City said.
The WHO confirmed that death on Monday.
Fourteen people have died of the disease in Vietnam while five
have died in Thailand.
"Beside the two cases, we have received more samples for
tests," the official said, adding that test results for a
Cambodian woman who had died from respiratory illness were
expected later on Monday.
The pregnant 24-year-old Cambodian woman who died last week in
a Vietnamese hospital was the impoverished country's first
suspected human victim of bird flu, said a WHO official in the
Cambodian capital, Phnom Penh.
Officials at Chau Doc hospital in Vietnam said the woman died
there last Friday of acute respiratory illness.
The virus has struck virtually all of Vietnam's 64 provinces
and major cities. Hanoi has ordered a nationwide ban on the
transport of poultry and a cull of all fowl in the capital.
The WHO said last week genetic tests on bird flu virus taken
from two Vietnamese sisters who died showed it had not acquired
the mutations needed to pass from person to person.
A Food and Agriculture Organization (FAO) official in Vietnam
said three or four pigs had tested positive for the virus, but an
FAO scientist in Rome later said the tests used were experimental
and played down the report.
Pigs and birds are both sources of new influenza viruses that
can infect humans, but the immune system of a pig is closer to
that of a human than is that of a bird. Scientists say pigs are
ideal vessels for mixing genes from bird flu and the human
influenza virus.
The world animal health body the Office International des
Epizooties (OIE) recommended that countries with avian flu
closely monitor pigs in contact with infected birds and cull
those in which the presence of the virus was confirmed.
Experts say the possibility of a new strain sweeping through a
human population with no immunity is remote, but each outbreak
narrows the odds a little.
That is one reason the FAO and WHO have been urging affected
countries to act swiftly to stamp out the H5N1 virus, preferably
by slaughtering poultry within three kilometers of an outbreak.
