New flu from pigs
What if we stopped raising pigs? Easy answer: we would stop the swine flu.
We pay a very high price from raising pigs and, of course, the pigs do as well. A big part of that price is the swine flu. U.S. health officials are tracking a newly discovered strain of swine flu in China they say has the characteristics of viruses with potential to cause another human pandemic. Although the virus has not yet been detected in the U.S. or shown human to human transition, doctors have reason to worry it could spell trouble.
Here’s why they’re worried. The new virus appears to grow well in the cells lining the human airway, and possesses all the essential hallmarks of being highly adapted to infect humans, according to a recent study.
Pigs are considered as important hosts or “mixing vessels” for the generation of pandemic influenza viruses. Systematic surveillance of influenza viruses in pigs is essential for early warning and preparedness for the next potential pandemic.
The virus, which scientists are calling G4 EA H1N1 is exhibiting “reassortment capabilities.” When you get a brand new virus that turns out to be a pandemic virus, it’s either due to mutations and/or the reassortment or exchanges of genes. This virus has characteristics of the 2009 H1N1 virus, and of the original 1918 Flu which some other flu viruses have, as well as segments from pigs. The H1N1 swine flu and 1918 pandemic flu were both considered very dangerous viruses that spread across the globe.
Most pigs are raised in very harsh over crowded conditions on what’s known as factory farms. But if we didn’t raise pigs, almost all the threat of swine flu would disappear.
