Just to Add
Just to add about the Spanish flu. It was very virulent compared with “normal” influenza strains, which has a mortality rate of less than 0.1% (I’m talking about the US, numbers may vary in other nations). But while the Spanish flu killed 675,000 Americans, the mortality rate was only 2.5%, and less than 5% overall. It was high compared to the standard run of the mill flu, but really quite low, as compared to something like Ebola.
The chicken flu spreading in Asia, in contrast, has a death rate of higher than 65%, although that seems to have dropped to about 35% in Vietnam. The first cases of humans catching a bird flu were back in 1997 in Hong Kong. So while the strain may be different, it seems that the virus may slowly be mutating to a form which infects humans.
Then again, put in perspective, the avian flu has killed hundreds of millions of birds. It has infected about 150 people in total (confirmed cases) in nations with very high population density and who often live in close proximity with their chickens and ducks. So out of hundreds of millions of people who have probably been in close contact with infected chickens, a minute number have actually become infected with it. Thus, it doesn’t seem like the virus is spread very easily between humans and birds at this point.
I also remember the panic over SARS a few years ago, which has all but been forgotten. That again, was also highly overhyped. SARS broke out in China, in a densely populated area, and weeks or even months passed before the strange new disease was noticed and quarantine measures were initiated. And yet a very small number of people were actually infected, despite the lack of precautions. The first infections were seen in China in November 2002. By July 2003, when the last case was reported, the SARS virus had infected over 8,000 people and killed 813. Considering that the virus had spread to over 24 countries including the USA, South America, Canada and Europe, and that it had gone virtually unchecked for weeks in China, that is a very small number of people. It doesn’t appear to have been very contagious, and I imagine that the death rate was this high because people didn’t initially seek medical help.
Anyway, this isn’t meant to downplay SARS but just to put things in perspective. SARS was not the deadly menace that mass hysteria, fueled by the media, made it out to be. Overhyping made it appear a lot more lethal and contagious than it really was. And now bird flu, which is still in its infancy stages. What concerns me is the report that the Spanish flu was also derived from birds, thus lending more support to the theory that this current strain circulating through chicken flocks in Asia does have the potential to mutate further and eventually be transmitted person to person.
Perhaps cleaning up the barnyard might be a start. Discouraging the consumption of raw chicken and chicken blood, which is how most humans appear to have contracted it. Better sanitation among chicken farmers, cleaner conditions, and so on, might keep the birds healthier. The factory chicken farmers in the US should pay special attention. Their birds are already doped up on antibiotics and hormones–a catastrophe waiting to happen.
