10 things you need to know
about Anthrax
·
Anthrax is an acute infectious disease caused by the spore-forming bacterium
Bacillus anthracis. It most commonly
occurs in mammals such as cattle, sheep, goats, camels, and antelopes, but
can also occur in humans when they are exposed to infected animals or tissue
from infected animals.
·
Anthrax is most common in agricultural regions where it occurs in animals.
Humans infected with anthrax usually have been exposed to infected
animal or their product through their occupations.
Workers who are exposed to dead animal and animal products from other
countries where anthrax is more common may become infected with Bacillus
anthracis.
3.
How is anthrax transmitted?
·
Anthrax infection can occur in three forms: cutaneous (skin), inhalation,
and gastrointestinal. Spores can
live in the soil for years, and humans can become infected with anthrax
by handling products from infected animals or by inhaling anthrax spores
from contaminated animal products. Eating
undercooked meat from infected animals also can spread the disease. It is rare to find infected animals in the United
States.
4.
What are the symptoms of anthrax?
·
They vary depending on how the disease was contracted, but symptoms usually
occur within seven days.
·
Cutaneous: About 95 percent of anthrax infections occur when the
bacterium enters a cut or abrasion on the skin, such as when handling contaminated
wool, hides, leather or hair products of infected animals. It begins as a raised itchy bump that resembles
an insect bite, but soon turns into a painless ulcer, usually one to three
centimeters in diameter, usually with a black center in the middle. Lymph glands in the adjacent area may swell. About 20 percent of untreated cases result in
death. The employee at NBC who contracted
anthrax has cutaneous anthrax.
·
Inhalation: Initial symptoms may resemble a common cold,
but lead to severe breathing problems and shock after several days. Inhalation anthrax is usually fatal. An employee of a Florida tabloid publishing
company contracted inhalation anthrax and died.
·
Intestinal: This form of anthrax may follow the consumption
of contaminated meat and is characterized by an acute inflammation of the
intestinal tract. Initial signs include
nausea, loss of appetite, vomiting and fever, followed by abdominal pain,
vomiting blood and severe diarrhea. Between
25 percent and 60 percent of cases are fatal.
5.
Where is anthrax usually found?
·
Anthrax is global. It is more common
in developing countries or countries without veterinary public health programs.
Certain regions of the world (South and Central America, Southern
and Eastern Europe, Asia, Africa, the Caribbean, and the Middle East) report
more anthrax in animals than elsewhere.
6.
Can anthrax be spread from
person to person?
·
Direct, person-to-person spread of anthrax is extremely unlikely. It is not contagious.
7.
Is there a treatment for anthrax?
·
Doctors can prescribe effective antibiotics. To be effective, treatment should be initiated
early. If left untreated, the disease
can be fatal.
8.
Is there a way to prevent infection?
·
In countries where anthrax is common and vaccination levels of animal
herds are low, humans should avoid contact with livestock and animal products
and not eat meat that has not been properly prepared. Also, an anthrax vaccine has been licensed for
use in humans. It is reported to
be 93 percent effective.
9.
What is the anthrax vaccine?
·
It is manufactured and distributed by BioPort Corp. of Lansing, Michigan.
It is a cell-free filtrate vaccine, which means it contains no dead
or live bacteria in the preparation. Anthrax
vaccines intended for animals should not be used in humans.
10.
Who should get vaccinated against
anthrax?
·
The CDCPs advisory committee on immunization practices recommends
vaccination for the following:
·
People who work directly with the organism in the laboratory.
·
People who work with imported animal hides or furs in areas where standards
are insufficient to prevent exposure to anthrax spores.
·
People who handle potentially infected animal products in high-incidence
areas. (Incidence is low in the United
States, but veterinarians who travel to work in other countries where incidence
is higher should consider getting vaccinated.)
For any unusual or suspicious letters, packages, substances or odors, please call 9-1-1. A procedure is in place with the police authorities to make a threat assessment on these incidents.
