Introduction.

In the late 1960s and early 1970s, many scientists felt that the battle against infectious disease had been won. Consequently, the health care community turned its attention toward cancer. However, since the mid- 1970s, diseases have been returning and new diseases emerging. Several new diseases have emerged, including AIDS, Lyme disease, Ebola, Hanta, West Nile, SARS, Monkeypox, and Bird Flu. In addition, to add to the crisis, many disease-causing bacteria have become resistant to commonly used antibiotics.

"That humanity had grossly underestimated the microbes was no longer, as the world approached the twenty-first century, a matter of doubt. The microbes were winning. The debate centered not on whether Homo sapiens was increasingly challenged by microscopic competitors for domination of the planet; rather, arguments among scientists focused on the whys, hows, and whens of an acknowledged threat."

From "The Coming of the Plague: Newly emerging diseases in a world out of balance", by Laurie Garrett. Penguin Books, 1994.

The U.S. Department of Agriculture (USDA) works together with Federal, State, and industry partners to protect the U.S. against the rapid spread of highly pathogenic H5N1 avian influenza (AI)


Map of Nations With Confirmed Cases H5N1 Avian Influenza (May 19) (If a larger map of the map to the right is not available at http://pandemicflu.gov/, click here.)


Bird flu (also known as avian flu or avian influenza), which has now spread from Asia to Europe, continues to pose a significant threat to human health and economic activity in the region and beyond.


"I personally believe it will happen and make personal preparations....Ý Society just can't accept the idea that 50 percent of the population could die. And I think we have to face that possibility....Ý I'm sorry if I'm making people a little frightened, but I feel it's my role."


"Unlike a hurricane that's confined to a specific area over a short time, a pandemic flu strikes everywhere and can last a year or more..." "No one can predict when a killer flu will strike, how bad it will be or even whether the virus will sustain its virulence after it begins to spread widely among humans. "It's clear the warning signs are troubling, but there is no certainty."


Because of concerns about the potential for more widespread infection in the human population, public health authorities closely monitor outbreaks of human illness associated with avian influenza. To date, human infections with avian influenza A viruses detected since 1997 have not resulted in sustained human-to-human transmission. However, because influenza A viruses have the potential to change and gain the ability to spread easily between people, monitoring for human infection and person-to-person transmission is important.


This thing is so deadly that we should not be downgrading this," said Eduardo Olivarez, chief administrative officer for the Hidalgo County Health Department. "If it does cross over to humans, it's going to become rampant.

Readings Introduced Species


These ants do not have stingers (unlike the red imported fire ant, Solenopsis invicta). In place of a stinger, is an acidopore, which can excrete chemicals for defense or attack. These ants, will however, bite. This behavior seems to be rare, but in some cases they will bite, causing a relatively sharp but quickly fading pain.
