Anthrax 101: What Is It And What Can It Do To Us?

As of Friday evening (October 12), four cases of anthrax had been reported in the United States since September 11, three in Florida and one in New York. In light of that disturbing news, you may be wondering what anthrax is exactly and what threat it poses to us?

Anthrax is an infectious disease that has been around for centuries. It is found most commonly in farm animals but humans can contract it three ways:

1. ingesting the anthrax bacteria by eating bad food, such as tainted meat

2. handling infected material such as powder, soil, animal skins or hides

3. inhaling microscopic anthrax spores, which are invisible to the naked eye

Anthrax can take anywhere from two days to two months to display symptoms. According to Allan Rosenfield, dean of the Mailman School of Public Health at Columbia University, “its initial symptoms are general symptoms, like the flu.” Later symptoms can include shock, coma, respiratory failure and, ultimately, death, depending on which strain of the disease is contracted.

According to the Center for Disease Control, 95 percent of anthrax cases are cutaneous, meaning they are contracted via physical contact with an infected material (soil, powder, animal skins, etc.). Only one in five of such cases will result in death, if treated. If one inhales anthrax spores, however, the chance of death rises dramatically. Data about intestinally contracted anthrax is less conclusive, with estimates about the likelihood of death varying widely.

Rosenfield points out that, unlike the flu, anthrax is not contagious. “If I have anthrax, you cannot get it from me. But if we’re both exposed to the same air, and anthrax is in the air, we may both come down with the disease, and it may take longer for you to get it than me.”

Prevention of anthrax is possible with a vaccine. But you must take it consistently for 18 months to become fully protected. The vaccine is regulated by the government, which is developing it for wider public use.

The good news is that, once exposed, victims can be treated with an antibiotic known as Ciproflaxin, or “Cipro”, which has displayed a high rate of success in curing anthrax patients. Two of the people who tested positive for exposure to anthrax in Florida and New York are reportedly taking Cipro and doing fine.

Don’t run out to your local pharmacy and begin stockpiling Cipro pills, though. Dr. Jim Walsh, a research fellow at the John F. Kennedy School of Government at Harvard University, has studied infectious diseases extensively and said, “Don’t waste your money on this stuff, it’s not going to make you any safer. There’s so much misinformation out there that we’re on the verge of hysteria. People are scared to death about anthrax when it really poses a very small threat.”

There have been threats and attempts to use anthrax as a weapon in the past. During the Gulf War in 1991, the specter of anthrax warfare loomed large over American troops in Iraq but never materialized. In 1995, a Japanese terror group piped anthrax into the Tokyo subway system several times with no effect. (They did, however, later succeed by using the poison gas sarin).

Infecting a population is not easy, according to Walsh. “It’s not quite as simple as stealing a crop duster and putting a bio agent in it,” he said. “It doesn’t work like that. You need sophisticated equipment, and it’s difficult to do.”

Difficult, but not impossible. Which is why the U.S. government is doing everything in its power to prevent and prepare for even the smallest possibility of biological terrorism.
