Terrorist Attacks in
London, U.K.
The
July 7th terror attacks on and the July 21st attempted bombings of the
London subway have raised the specter of terrorism threats in Europe
and abroad. Through statements to the press and appeals to the
general public, British authorities are helping to learn the identities
of the suspected bombers, track their movements over the last few
years, describe the safety measures being enacted to help ensure public
safety, and enlist assistance in identifying "suspicious" materials or
individuals. In the United States, increased attention is being
paid to securing transportation infrastructure (especially trains),
also with appeals to passengers to report anything they believe to be
suspicious.
Terrorism is an ongoing threat and during terrorist
attacks, good information is at a premium.

Childhood
vaccination
and autism - what is the risk?
Over the last several years, debate has centered on
whether a mercury-based preservative once widely used in childhood
vaccines causes autism. Rates of the neurological
developmental disorder - one that is still poorly understood
scientifically - have risen sharply in recent years. Although
epidemiological studies and expert review panels have not found any
evidence of a link, debate continues, involving parents, public health
professionals, medical doctors, vaccine
makers, and politicians. Effective risk communication in this
case involves providing clear information about the benefits of
childhood vaccines, what is currently known about its relationship to
autism, and what exactly autism is as a disorder.

CNN

2nd case of Mad Cow
Disease in U.S. cattle
On June 24th, the United States Department of Agriculture (USDA)
announced that a 2nd U.S. cow had tested positive for Mad Cow Disease
(also known as BSE - Bovine Spongiform Encephalopathy). The cow
was first tested last year, with final confirmation from a British lab
received last week. Mad Cow Disease has received heavy coverage
in recent years, especially in Great Britain, where the disease was
suspected in causing a variant of BSE in humans who ate contaminated
meat. Mad Cow Disease is, of course, a real concern to the food
supply, and effective risk communication involves disseminating
information about what the disease is, what danger is poses to a
nation's food supply, how many cases (if any) have been diagnosed in
cattle and humans, and what actions are being taken to prevent its
spread.

On July 11th, the USDA announced that testing on the other members of
the herd where the infected cow came from were all negative for
BSE.

Homeland
Security
The U.S. Government Accountability Office (GAO) recently
released a report about possible applications of risk communication to
the federal Homeland Security Advisory System. Since the 9/11
attacks, the color-coded Homeland Security Advisory System has
functioned with the goal of communicating the risk of terrorist attacks
to law enforcement, emergency responders, and the general public, among
other groups. This system, according to GAO, faces numerous
challenges, namely a shortfall in
disseminating threat-specific information in a timely manner. In
its report, GAO issues several recommendations to make the System more
timely, accurate and precise.
