The Basics
What flight
attendants need to know
Tuberculosis (TB)
is a serious respiratory disease that can be spread throughout the world by
global air travel. Growing numbers of passengers are flying to and from regions
of the world where tuberculosis (TB), avian flu, and other infectious
communicable diseases are endemic. A 1998
report by the World Health Organization (WHO) estimated that
"[a]pproximately one third of the world’s population is infected with
Mycobacterium tuberculosis, and TB is the leading cause of death from a single
infectious agent in adults worldwide.”
Flight attendants
should be aware of the potential for exposure to this disease, and remain
vigilant about their health. According to a WHO Factsheet,
TB “spreads through the air. Only people who are sick with TB in their lungs
are infectious. When infectious people cough, sneeze, talk or spit, they propel
TB germs, known as bacilli, into the air. A person needs only to inhale a small
number of these to be infected.” If you have come in contact with someone
who is known to have an active case of TB, you should immediately contact your
primary care physician or an infectious disease specialist, and seek emergency
care if needed. If you would like further information or assistance,
contact your AFA Employee Assistance Program representative.
Maximizing the
airflow to the cabin can reduce your risk of exposure to airborne viruses or
bacteria. Encourage your airline and pilots to turn up the air packs to
"high" whenever possible. Most airplanes use about 50% re-circulated
air, which should first be passed through high efficiency filters to prevent
germs from being re-circulated throughout the cabin. These filters should be
replaced at least as regularly as the manufacturers recommend. Right now,
there are no real air quality standards for airplane cabins, and the airlines
often reduce airflow to save fuel and lengthen the time between filter
replacements. Crew and passengers need to speak up.
The
latest, most complete information on TB is available from the World Health Organization
(WHO) and the Centers for
Disease Control and Prevention (CDC).
