BIRD FLU
Three quarter of the cases of bird flu worldwide in VN
Many victims brought to one hospital in Southern city of HCM
I went to see a doctor lived and worked there 10 years, witnessed the devastation of H5N1
Without natural defenses, immune reaction literally destroyed the lungs
Doctor: X-ray of a normal patient, black area is where we breath through. Here is a patient admitted in January with H5N1, on admission to hospital - black area of right lung completely destroyed, very little gas exchange, still have a little bit of lung and can breathe on their own without assistance. Two days later, whole lung tissue destroyed, no longer able to breathe for themselves. The patient died a day after this picture taken
The virus originate in birds
In VN, the poultry population exploded in recent years
Humans and their birds are brought to close contacts
The greatest danger is when poultering birds infected with flu virus
People can breathe in drops of blood, saliva, and feces
Eating infected poultry not properly cooked can be catching disease
Ducks often carry it without any sign of ill health
This new Avian strain of bird flu has become endemic in VN
Winter approaching, flu season about to start
Doctor and medical staffs are carrying patients with malaria and Dengue fever, but they expect to soon see a new wave of bird flu cases
Doctor: We have to assume this going to happen, and try to prepare for that
This new flu strain first trans from birds to humans in Hongkong 8 years ago, in China
122 confirmed cases in VN, Cam, Thai, Indo in the past three years
1918
The last pandemic by Avian bird flu infected half of the population joining the first world war, killed 50 million people in 3 distinguish global waves of disease
Flu pandemics are not natural phenomena, there are 2 less outbreak in the last century
Doctor researched the origin virus caused 1918 pandemic, took samples of lung tissue to isolate the bird flu strain, Northern France
Doctor: First month, there are 50 cases, to geese, swans, ducks, chickens, buy from market in the nearby village, helping carry the virus
Like the bird flu today, 1918 strain on young healthy adults not the elderly have better immunity
Doctor: A piece of lung from 1918 pandemic, look at the genetic footprint of the 1918 and the virus today. It gained another warning, H5N1 has a little too likeness to 1918 virus
So far, H5N1 only infected a person on 122 documented occasions, hasn’t spread beyond these people
Global pandemic occurs when a flu virus finds a way to transmit easily from person to person
To do that, H5N1 either need to change gradually as happened in 1918 or to mix with the seasonal human virus inside a person. Either would create a high contagious and deadly strain
Doctor: It has been around 5-6 years, probably a billion people has been exposed to it. It not showing any sign of mutating into a human strain or mixing with the human flu virus but it might happen in a short or long time. Or even the third scenario, it could be an entirely different type of bird flu strain we not yet known about. All of those scenarios are possible
An epidemiologist studied the path of infection and effects on society
The longer between flu pandemic, the less immunity there is in population
Professor plans to send her children to the country to try to protect them from infection if a pandemic breaks out
Professor: Hopefully you get far from the pandemics, control will be much better. (The warning may not happen at all) I think it will happen, it might not happen soon. But the problem is if it does happen, it could be so bad.
VN with 80 million people and H5N1 in poultry is at risk of a serious outbreak
Each new case of bird flu in a person gives the virus an opportunity to change to something able to pass easily from person to person, the precondition for a pandemic
What is happening in population in recent months raises the disturbing possibility that the virus is mutating
Visit HN Infectious Diseases Hospital where doctors solve 33 bird flu inpatients last year from Northern VN
The medical staffs reconsidered there’s a high risk to them from nursing such patients
Now they’re worried there are signs the virus evolving
Virus changed it form and strain, sometimes make the disease worse, sometimes less severe
We have sent our … to other countries to test and the result show the virus changed
In the past year, nearly three times as many VNese got bird flu virus as in the previous year, but more are surviving
But to the doctor watched it spread for the past 2 years, that is hardly reassuring
In this virus so far, 50 or 60% of people get infection die, and of course that virus die with that patient.It absolutely tragic for that patient and their family.But in term of spreading the virus, it actually very good news in population level because that virus can’t go on. The worry will be if the virus starts to kill fewer people but infect more, then we have what we had in 1918, a chance for global pandemic
