The problems with the Department of Homeland Security

Laura H. Kahn

In response to 9/11, Congress created the Department of Homeland Security (DHS), a massive cabinet-level agency that consolidated 22 departments and agencies and almost 200,000 federal employees. Its goal was to improve domestic security coordination and communication.

Stirring up "swine flu" hysteria

Laura H. Kahn

All disease crises begin with some level of chaos and confusion, particularly when a novel microbe is involved. The current influenza A (H1N1) crisis--referred to by the media as "swine flu"--isn't an exception. The notable difference is the level of hysteria it inspired.

Who's in charge during the swine flu crisis?

Laura H. Kahn

As the swine flu crisis worsens, effective disease control will require political and public health leadership at the federal, state, and local levels. Like the deadly influenza virus of 1918 that took more lives than World War I, this latest virus is an H1N1 strain and has the potential to develop into a major pandemic. Already, the virus has infected more than 150 people in Mexico and has spread to New York City and other parts of the United States.

Licensing life science researchers

Laura H. Kahn

In a previous column, I discussed how the recent U.S. buildup of high-containment biodefense laboratories might inadvertently increase the risk of another bioterrorist attack by increasing the number of researchers who have expertise and access to dangerous pathogens. One response to this risk has been to oversee research facilities and monitor the acquisition of microbes.

The threat of emerging ocean diseases

Laura H. Kahn

Much attention has been paid to newly emergent diseases that have afflicted humans in recent decades--HIV/AIDS, SARS, avian influenza, etc. Conversely, deadly diseases that have emerged in the world's oceans during the same time period have been largely ignored. While these diseases haven't caused epidemics in humans, they have proved troublesome to marine animal populations and to susceptible humans who have ventured into contaminated waters.

Modeling disease spread

Laura H. Kahn

Many things went wrong during Britain's 2001 foot-and-mouth disease crisis. Initial efforts at identifying infected animals, slaughtering them, and burying their carcasses within 24 hours--the tried-and-true method for containing the disease--were sluggish at best. And the country's Ministry of Agriculture, Fisheries, and Food (MAFF), still reeling from criticism about how it handled the country's decade-long mad cow disease epidemic, was unprepared for the severity of the foot-and-mouth outbreak.

Unifying the U.S. government response to bioterrorism

Laura H. Kahn

Of the many ways in which the United States is unprepared to deal with an infectious disease outbreak or bioterrorist attack, here's one of the most problematic: The responsibility for public health is a state concern.

The role of bats in disease transmission

Laura H. Kahn

Bats are considered mysterious creatures and often generate fear. Specifically, South American vampire bats feed on animal blood and possess a legendary lore. But more importantly, bats are the host species for deadly diseases such as rabies, Nipah and Hendra viruses, and SARS. There's also evidence that they continue to serve as sources of novel emerging viruses.

Strong health care equals strong emergency response

Laura H. Kahn

In previous columns, I've discussed the consequences that will result during a pandemic or bioterrorist attack from not insuring all Americans and providing adequate primary care--see "The Security Impact of the Uninsured" and "The Exodus of General Medical Physicians." What I haven't discussed is that the U.S.

Health-care realities during a pandemic

Laura H. Kahn

Despite the availability of antiviral medications and intensive care units, mortality rates for the 385 humans infected with avian influenza remain high. Virtually all of the victims have been from developing countries, with the case fatality rate in children younger than 15 years of age reaching  almost 90 percent.
