Smallpox is one of this year's top 10 medical stories. Not bad
for a disease that's been dead for a quarter of a century.
Ironically, it was only last October that the CDC celebrated
the 25th anniversary of the last case of smallpox in the world. Smallpox is
eradicated. It stands as one of mankind's greatest achievements.
By Shari SimsThere's a new, more sensitive way to screen for cervical cancer — yet only 15 percent of doctors are using it. Why the Pap may no longer be enough.
Suppose there were a screening test for cervical cancer that could detect potential dangers with far more sensitivity than the Pap. A test so reliable that when it was done with the Pap, you could trust the results nearly 100 percent. Sounds like all women would be getting it, right? Well...there is such a screen — the HPV test. It's been...
Now we fear that one of mankind's lowest acts -- terrorism --
might resurrect what 19th-century historian Thomas Macaulay called "the
most terrible of the ministers of death." We worry that Soviet Cold War-era
smallpox bioweapons might find their way into the hands of terrorists. We worry
that rogue states might somehow develop and distribute smallpox weapons. We
worry -- and now we prepare for the worst.
"The smallpox virus still exists in laboratories, and we
believe that regimes hostile to the United States may possess this dangerous
virus," President Bush said on Dec. 13. "Our government has no
information that a smallpox attack is imminent. Yet it is prudent to prepare
for the possibility that terrorists who kill indiscriminately would use
diseases as a weapon."
To this end, the U.S. already has begun an ambitious smallpox
vaccination program. About a half-million military personnel not deferred for
medical reasons must get vaccinated. Another half-million healthcare workers
will get voluntary vaccinations. After that, another 10 million healthcare
workers will be offered the vaccine. The general public eventually will be able
to choose vaccination. But unless there's an attack, no mass vaccination
program is planned.
What is the Real Threat?
For every million people who get the vaccine, thousands will
get bad reactions and one to five people will die. As Bugs Bunny used to ask in
WWII-era cartoons, is this trip really necessary?
One person dealing with some of the issues involved is Kent A.
Sepkowitz, MD, director of infection control at Memorial Sloan Kettering Cancer
Center and associate professor of medicine at Weill Medical College, Cornel
University, New York.
"What is threat of smallpox? I have no idea," Sepkowitz
tells WebMD. "That is the key piece. Nobody knows. That information is
missing. We are asked to take on blind faith that there is a threat and to make
a plan. It is our job to wrestle with the issues."
