Cultures across the world, for eons, have justified the slaughter of animals for the consumption of mankind, ‘because God/Nature created them for our sustenance.’ But today, sustenance has become the cornerstone of commerce and the meat industry, allegedly, has become a needlessly cruel and literally blood-thirsty enterprise. So now, is the animal farm hitting back? ‘Swine flu’ (H1N1 virus) is the latest incursion on the western world and is worrying everyone around. As the name suggests, it is the virus that often causes influenza outbreaks in pigs, especially during the late fall and winter months. While the season of the outbreaks of ‘common cold’ in pigs is similar to humans, the symptoms (running nose, coughing, sneezing, fever, laziness etc.) are surprisingly similar too. Normally, the swine flu virus does not infect humans. It is the direct exposure to pigs in either a breeding farm or fun fair that leads to infection in humans and is contagious like regular influenza. “It is a different strain. Though cold and cough are the symptoms, the body might not be immune to it. In those cases, it can take shape of a lethal pneumonia and may cause death,” says Dr. S. M. Sachdeva, Senior Consultant Cardiologist.
It is the horrifying memory of the biggest and the deadliest global endemic, Spanish Flu (a subtype of H1N1 virus and similar to swine flu) of 1918 which causes concern and panic every time such influenzas surface. It shook the world when 40 million people died. In Spanish Flu, pneumonia doesn’t even get the time to establish itself and the patient dies of the virus within hours of contracting it. The virus causes an uncontrollable hemorrhaging that fills the patient’s lungs with his own body fluids.
If one observes keenly, there are certain peculiarities about these outbreaks, about the kind of victims as well as about the recurrence of such virus attacks. While the Spanish flu presented an unusual preference in its choice of victims – young, healthy adults instead of those with weak immune systems – the origin of the ailment is considered to be in the Eastern world.
Again, an entirely new variety of human influenza, ‘Chicken Ebola,’ surfaced in the human population of Hong Kong in 1997. It was then that Hong Kong’s entire poultry population (ducks, geese and chickens) was slaughtered. SARS or bird flu also started among the Orientals and culling of several poultry animals was done to avoid it from gaining pandemic proportions. As far as the recurrence of these influenzas is concerned, influenza experts remind that aquatic birds maintain all the genes of all influenza viruses in the world and they transmit it to other species periodically. Even if these viruses are very ancient, they still have the capacity to evolve, to acquire new genes and new hosts. So, chances of such troubles hitting mankind again can’t be ignored.
While the 1918 Spanish flu took its toll in the pre-penicillin era, new types of viruses always pose a threat. It is quite clear that breeding farms for poultry and pig are the breeding grounds for such viruses. Well, the increased frequency of recurrence of such influenzas in the past one decade could be nature’s way of telling us that culling humans too isn’t as difficult!
