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.

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.

Biosecurity lessons from the Bruce Ivins case

Laura H. Kahn

We'll never know if Bruce Ivins, a former U.S. government microbiologist, perpetrated the 2001 anthrax letter killings, but the circumstantial evidence is pretty convincing. The DNA of the anthrax strain used in the killings matched the anthrax strain in his laboratory. Searches of his home in Frederick, Maryland, turned up "hundreds" of letters similar to those used in the terrorist attacks.

Food-borne illness: Attack of the killer tomatoes

How evil can prevail in state-sanctioned biowarfare research

Laura H. Kahn

Some people consider physician Wouter Basson South Africa's Josef Mengele. During the 1998 Truth and Reconciliation hearings on Project Coast, South Africa's apartheid-era chemical and biowarfare programs, Schalk Janse van Rensburg, a veterinarian, stated that Basson, the program's head, wanted to devise a way to kill individuals that would appear undetectable to a forensics laboratory.

The furor over genetically modified foods

Laura H. Kahn

The United Nations estimates that world population will top 9 billion people by 2050. Combined with the anticipated consequences of global warming such as drought, this could lead to devastating food shortages.

In pursuit of international biosecurity oversight

Laura H. Kahn

Without a doubt, the implementation of bioresearch oversight must be an international effort. The United States has tried to take the lead in this area by mandating its National Science Advisory Board for Biosecurity to foster international collaboration when reviewing dual-use bioresearch.

The potential dangers in medical isotope production

Laura H. Kahn

The medical isotope metastable technetium 99 emits gamma rays that physicians heavily rely upon to examine how organs such as hearts, lungs, and kidneys function. Technetium 99 is so beneficial to the medical community that it's used in approximately 80-85 percent of the world's diagnostic imaging procedures (cardiac perfusion scans and bone scans among them) and 12 million procedures in the United States alone. The size of the global nuclear imaging and therapeutics market is estimated at $3.7 billion per year.
