Vietnam has ordered the culling of chickens in all 12 regions
engaged in the bird flu epidemic.
This is one of a number of strict measures proposed by the
Vietnamese Ministry of Agriculture and Rural Development to
stop the spread of bird flu around the country.
Vietnamese reports have revealed that 18 people may have
been infected by the H5N1 strain of avian influenza and 13
people have died so far.
Are the measures taken by the Vietnamese officials enough
to curb the outspread of a bird flu epidemic?
Valarie Tan put this question to Mr Peter Cordingley (PC),
WHO's Spokesperson for the Western Pacific.
PC: The truth of the matter is we don't know. We don't know
because we don't have people out in the field at the moment
looking at what's going on. What we do know is that Vietnam
has got an enormous problem on its hands to kill all these
chickens. And they do have to be killed. The Vietnamese chicken
industry is not like those in the west - there are small farms,
there are large farms, there are chickens in the backyard,
chickens in the streets, all these chickens have to be found,
rounded up and killed.
Even though currently the virus highly contagious among chickens
is believed to spread to humans through contact with faeces
of infected birds, WHO has said that if human-to-human transmission
occurs, this could be worse than SARS. So what can they do
to prevent a human-to-human transmission?
PC: When WHO says that its deadlier than SARS, that's a doomsday
scenario.
Its subject to all kinds of conditions. There's no evidence
at all in any of the cases in Vietnam that human-to-human
transmission is going on. When there's transmission from chicken
to human, it looks like a dead-end transmission. The virus
has caused damage, its killed people certainly, but it has
not moved on to other people.
What happens if human to human transmission occurs?
PC: Well, we do have defences against human influenza, we
have vaccines there are some drugs out there that do actually
cure. There are public health measures that can be taken.
But I want to stress, that yes it could be worse than SARS,
because there are obvious things that could happen that would
be a really serious danger to international public health.
But those things to happen, they have to be in place but they
are not in place at the moment.
Vietnam is definitely in a great state of urgency now. Vietnamese
officials are also taking the matter very seriously. Do they
have enough resources and manpower to contain the virus and
prevent it from spreading?
PC: No, quite obviously the Vietnamese need all the international
help it can get. We've got people in there, we're going to
get more people in there. Vital to the effort is the assistance
of the Food and Agricultural Organisation, the FOA which has
enormous expertise of culling chickens and managing crisis
like this. Well, Dr Hitashi Oshitani who's the doctor who
here in Manila led the response to the SARs outbreak has flown
to Hanoi to lead the response to the bird flu crisis. He's
got two jobs to do. One of them is to draw up some case definitions,
just like we have with SARS in the early stages. Remember
we put out this message that if you have a fever of more than
38, if you have a dry and productive cough, if you have light
breathing problems, seek medical help. They'll be looking
at the cases in Vietnam studying the case definitions. And
the second thing he's got to do, is to put together an international
team. They'll be fanned out across the country, taking their
special skills with them. And when that happens, we have a
better reading of how serious the situation is.
