Vietnam confirms first human bird flu case in year and a half
Vietnam on Wednesday [23 May 2007] confirmed its 1st human bird flu
case in a year and a half, as the virus continues to spread through
the country's poultry stocks.
A 30-year-old man from northern Vinh Phuc province remains
hospitalized and breathing through a respirator after testing
positive for the H5N1 virus 3 days ago, said Tran Quy, director of
Bach Mai hospital in Hanoi.
"The man is in critical condition," he said. "He has a high fever,
difficulty breathing, coughing and the X-ray of his lung was
completely white. All these are typical bird flu symptoms."
Quy said the man was admitted to the hospital last week. Relatives
said he had helped prepare chickens for a wedding reception before falling ill.
It is the country's 1st human infection of H5N1 since November 2005
and comes as bird flu outbreaks among poultry have been reported in
southern, central and northern Vietnam.
Samples of the virus will be shipped to a World Health Organization
lab for analysis and reconfirmation, said WHO country representative
"We are following up with the Ministry of Health about it to get more
details," he said. "Since we know there is a risk for transmission to
people, it's not really a surprise. It could just be one isolated case."
Vietnam had been hailed a success story for beating back the virus
that began ravaging Asian poultry stocks in late 2003. A nationwide
mass poultry vaccination program, coupled with strong political will,
brought the virus under control after it killed 42 people in the
country. No poultry outbreaks were reported in 2006, but the virus
flared again early this year.
The H5N1 virus remains hard for people to catch, but experts fear it
could mutate into a form that spreads easily among people. It has
killed up to 185 people worldwide, according to the World Health Organization.
[As stated in the above newswire, the last reported human case of
H5N1 infection in Viet Nam was in 2005. According to the WHO website
on avian influenza
in 2003 there were 3 cases with 3 deaths reported in Viet Nam (case
fatality rate [CRF] 100 percent); in 2004 there were 29 cases with 20
deaths reported in Viet Nam (CFR 69 percent) and in 2005 there were
61 cases with 19 deaths reported from Viet Nam (CFR 31 percent),
bringing the overall total of reported cases to 93 with 42 deaths
(CRF 45 percent). There have been recent reports of spread of H5N1
infection among poultry in Viet Nam (see prior PRO/MBDS postings
Avian influenza - MBDS region (19): Viet Nam 20070522.1635 and Avian
influenza - MBDS region (18): Viet Nam, RFI 20070506.1464) with
significant geographic spread of these outbreaks in the past week.
Vinh Phuc Province is adjacent to the northwest portion of Hanoi
Province (see <http://www.angelfire.com/co/hongnam/vnmap.html>; and
for maps of Viet Nam with provinces). According to the earlier
report on the increased numbers of poultry outbreaks, while all 6
involved provinces were not mentioned, there was mention of an
outbreak in Son La Province, 2 provinces to the west of Vinh Phuc
Province where this present human case is from. More information on
the epidemiology of this present case would be appreciated. - Mod.MPP]
