The rub for Vick

Michael Vick is in a fighting mood. He plead not guilty to multiple charges related to his pit bull fighting operation called Bad Newz Kennels. If the charges are true, Michael Vick has company: according to some estimates 40,000 people attend, organize, or breed for dog fighting.

Pit bulls are the dog of choice, with good reason. According to a study by Merritt Clifton, pit bulls, Rottweilers, and Presa Canarios are responsible for 74% of dog attacks. Here’s the scary part: Over two-thirds of the time, life-threatening or fatal attacks were the dog’s first known dangerous behavior.

Michael Vick knows that dogs can be dangerous. The Centers for Disease Control and Prevention in Atlanta, otherwise know as the CDC, said that each year dogs bite nearly 2% of the U.S. population – that’s 4.7 million people. Of those, nearly 800,000 require medical treatment, with over a thousand people a day visiting emergency rooms, dog bites being the second most common cause of emergency room visits by children. The annual cost to dog attack victims is estimated at over one billion dollars.

You might be surprised who else owns pit bulls. Among the estimated ten million pit bull owners in the US are Jessica Alba, Michael J. Fox, Alicia Silverstone, Jessica Biel (she has three), Rachel Ray, and Jon Stewart.

Michael Vick must have known this venture would make the news eventually. Can you imagine going on vacation and leaving your dog with Bad Newz Kennels? Well, let me give Vick the benefit of the doubt: maybe the name means they teach the dogs how to read the New York Times, the Wall Street Journal, or 18-count indictments.

Tuberculosis

A new strain of an ancient disease may be spreading, aided by modern technology. A man in love and with XDR TB – I’ll call him Typhoid Phil since his name has not been released – flew from Atlanta to Paris to get married in Greece and then flew from Prague to Montreal on a circuitous route home to Atlanta, possibly infecting dozens of fellow travelers.

XDR TB is Extensively Drug Resistant Tuberculosis. The CDC says XDR TB is highly communicable, that is, prolonged contact with XDR TB will likely result in getting the disease. Consistent with that belief they are contacting everyone on those two trans-Atlantic flights to warn them and – if they sat within two rows of Mr. Newlywed – to test them.

Is anyone else thinking what I’m thinking? What about Typhoid Phil’s new wife? Does she have XDR TB? The CDC said she tested negative before the trip and is not considered a public health risk. Did she somehow develop a resistance to it? And is the CDC testing her to find out why and find a cure? Just in case is she in isolation like her husband? With her husband?

I’m confused. Lots of questions, contradictory information. A perfect situation for good sound mathematical analysis. First let’s look at some numbers.

The US TB rate has steadily declined and last year hit an all-time low of 4.6 cases per 100,000 Americans. That’s just under 14,000 cases in 2006. XDR TB? There have been just 17 cases since 2000, which means that XDR-TB infects just 1 in 100 million people each year in the US. But we’re talking about a serious disease here: 1.6 million people die annually from TB.

Scientific studies often consider spouses of TB sufferers to be resistant. One thing is for sure, this marriage is off to an interesting start. And with Typhoid Phil’s wife resistant to his TB but not to his charms, I hope it lasts forever.
