Q: What is anthrax?
Anthrax is an acute, infectious disease caused by the
spore-forming bacterium Bacillus anthracis. The cutaneous form
(contracted through the skin) is the most common and is less deadly than
the inhalation, or pulmonary, form (contracted through inhaling the
spores).
Q: How do I get it?
It is transmitted by humans handling products from infected
animals or contaminated materials, or by inhaling anthrax spores.
Q: Is anthrax contagious?
There is no evidence of direct person-toperson spread of
anthrax.
Q: What are the symptoms of anthrax infection?
Symptoms of the disease vary depending on how the disease was
contracted. Cutaneous: Most (about 95 percent) anthrax infections occur
when the bacterium enters a cut or abrasion on the skin, or when
handling contaminated wool, hides, leather or hair products of infected
animals. Skin infections begin as a raised itchy bump that resembles an
insect bite but within 1 to 2 days develops into a blister and then a
painless ulcer. Lymph glands in adjacent areas may swell. Inhalation:
Initial symptoms may resemble the common cold. After several days, the
symptoms may progress to severe breathing problems and shock.
Gastrointestinal: Infection may follow the consumption of contaminated
meat and is characterized by an acute inflammation of the intestinal
tract. Initial signs of nausea, loss of appetite, vomiting and fever,
are followed by abdominal pain and severe diarrhea
Q: When do symptoms appear?
Symptoms usually appear within seven days of exposure to the
anthrax bacteria
Q: How common is anthrax?
Anthrax is most common in agricultural regions, where it occurs
in animals. These include South and Central America, Southern and
Eastern Europe, Asia, Africa, the Caribbean and the Middle East. When
anthrax affects humans, it is usually due to an occupational exposure to
infected animals or their products. Anthrax in wild livestock has
occurred in the United States, but it is rare.
Q: Can the disease be treated?
Yes. Treatment with appropriate antibiotics is effective, but
timing is crucial: a delay of even hours can inhibit effectiveness.
There are three types of approved antibiotics for anthrax: ciprofloxacin
(Cipro®), tetracyclines (including doxycycline) and penicillins. People
who have been exposed to anthrax but do not have symptoms should consult
with a medical professional who will determine the best course of action
for recovery.
Q: Should I ask my doctor to write a
prescription for antibiotics so that I can take them as a precautionary
measure?
No. The Red Cross supports the Center for
Disease Control and Prevention’s (CDC) recommendation against taking
unnecessary antibiotics for possible anthrax exposure. Taking
antibiotics will not make you immune to the disease and could lower your
ability to fight other illnesses. Widespread use of antibiotics could
also lead to organisms developing resistance to these drugs, making them
ineffective. Federal health officials have ample supplies of needed
drugs and medical supplies they can deliver anywhere in the United
States within 12 hours of a request for assistance.
Q: Is a vaccine available?
An anthrax vaccine was licensed by the Food and Drug
Administration (FDA) in 1970 for at-risk veterinary and laboratory
workers and livestock handlers. The Department of Defense also reserves
a stockpile of the vaccine for military use and for some anthrax
researchers. The vaccine is in short supply and not available to the
general public.
Q: Is anthrax easy to use as a biological
weapon?
The spores have to be turned into a microscopically fine powder
of a certain size to be absorbed by the lungs and released in a certain
way in order to be effective. This is difficult to do.
Q: Does the government have a plan in place to
make antibiotics available in the event of mass exposure?
Yes. The CDC’s National Pharmaceutical Stockpile is available
to any community in need of additional medicinal support in response to
an event involving any biological agent. It consists of several tons of
the necessary pharmaceutical supplies and equipment, strategically
located throughout the United States, that will be delivered to the
local community within 12 hours of an event taking place. The Federal
Response Plan does not need to be activated in order for the stockpile
to be utilized by a local community.
Q: Are blood or blood products used as a
treatment for anthrax infection?
Antibiotics are the primary treatment for an anthrax infection.
Neither blood nor blood products are used in a case of anthrax infection
unless the patient has another condition requiring blood or blood
products.
Q: Can anthrax affect donated blood?
The FDA issued guidance on October 17, 2001, stating that there
is no known risk of transmission of anthrax from blood collected from
donors who might have been exposed to the anthrax bacterium but were
still in good health. The appearance of anthrax bacteria in the blood of
an infected person is thought to coincide very closely with the onset of
fever and other symptoms of a serious illness. Thus, standard blood
donation screening procedures that exclude sick persons from donating
blood are expected to result in deferral of donors who otherwise might
transmit the disease. However, if a blood donor later reports a
confirmed medical diagnosis of anthrax around the time of the donation,
the American Red Cross will withdraw that person’s donation and remove
it from use.
Q: What should I do if I receive a suspicious
unopened letter or package with a threatening message such as “Anthrax”?
You should:
- Not open, shake or empty the contents of any
suspicious envelope or package.
- Place the envelope or package in a plastic bag or
other container to prevent leakage of contents.
- Cover the envelope or package with anything (e.g.,
clothing, paper, trash can), if you do not have a container, and do
not remove this cover. Then leave the room and close the door, or
section off the area to prevent others from entering.
- Wash your hands with soap and water to prevent
spreading any powder to your face.
- Next
- If you are at home, report the incident to
local police.
- If you are at work, report the incident to
local police,
and notify your building security official
or an available supervisor.
- List all people who were in the room or area when the suspicious
letter or package was recognized. Give this list to both the local
public health authorities and law enforcement officials for
follow-up investigations and advice.
Q: What should I do if I open an envelope or
package and powder spills out?
You should:
- Not try to clean up the powder. Cover the spilled
contents immediately with anything (e.g., clothing, paper, trash
can) and do not remove this cover!
- Leave the room and close the door, or section off
the area to prevent others from entering.
- Wash your hands with soap and water to prevent
spreading any powder to your face.
- .Next…
- If you are at home, report the incident to
local police,
- If you are at work, report the incident to
local police,
and notify your building security official or an available
supervisor.
- Remove contaminated clothing as soon as possible
and place in a plastic bag, or some other container that can be
sealed. This clothing bag should be given to the emergency
responders for proper handling.
- Shower with soap and water as soon as possible. Do
not use bleach or other disinfectant on your skin.
- If possible, list all people who were in the room
or area, especially those who had actual contact with the powder.
Give this list to both the local public health authorities so that
proper instructions can be given for medical follow-up, and to law
enforcement officials for further investigation.
Q: How can I identify a suspicious package or
letter?
According to the U.S. Postal Service, typical characteristics
of suspicious letters or parcels include those that—
- Have any powdery substance on the outside.
- Are unexpected or from someone unfamiliar to you.
- Have excessive postage, handwritten or poorly typed
address, incorrect titles or titles with no name, or misspellings of
common words.
- Are addressed to someone no longer with your
organization or are otherwise outdated.
- Have no return address, or have one that can’t be
verified as legitimate.
- Are of unusual weight, given their size, or are
lopsided or oddly shaped.
- Have an unusual amount of tape. • Are marked with
restrictive endorsements, such as “Personal” or “Confidential.”
- Have strange odors or stains.
Q: What should I do if I suspect that a
biological agent has been released into the air?
You should:
- Turn off fans or ventilation units in the area.
- Leave the area immediately.
- Close the door, or section off the area to prevent
others from entering.
- Next…
- If you are at home, call 9-1-1 or your local
emergency number to report the incident to local police. They
will notify the FBI and other appropriate authorities.
- If you are at work, call 9-1-1 or your local
emergency number to report the incident to local police who in
turn will notify the FBI and other appropriate authorities.
Also, notify your building security official or an available
supervisor.
- Shut down the air handling system in the building,
if possible.
- If possible, list all the people who were in the
room or area. Give this list to both the local public health
authorities so that proper instructions can be given for medical
followup, and to law enforcement officials for further
investigation.
Q: Should I buy a gas mask?
No. The Red Cross supports the CDC’s recommendation that it
is not necessary to purchase a gas mask. In the event of a public health
emergency, local and state health departments will inform the public
about the actions individuals need to take.
Q: I haven’t opened a suspicious letter and
have no evidence of an aerial release of an agent but am still worried
about possible infection. Who should I contact in my local area if I’m
still worried?
Contact your local health department, or your doctor, for more
information if you are worried about anthrax exposure. Don’t start
taking antibiotics unless advised to do so by your doctor or by health
authorities.
