Anthrax is an infection caused by bacteria which form protective spores to survive in extreme conditions, enabling it to survive for long periods of time. When we come into contact with these spores an infection may result, but not always. Anthrax can be quite difficult to contract. There are three distinct types of anthrax infection:
- Cutaneous anthrax (skin)
This is the most common infection caused by skin contact, where the spores enter any cuts or tiny abrasions in the skin. A raised itchy area develops, with a black scab forming in the centre. This was the most common infection in the 2001 American postal incidents.
- Pulmonary anthrax (lungs)
This is where a number of spores have been inhaled and pneumonia results two to three days after exposure. Following the 2001 incidents in America, only one elderly person has died from this form of anthrax - probably because it was not diagnosed quickly enough, as it is so rarely seen.
- Gastrointestinal anthrax (digestive)
This is an extremely rare infection where large numbers of organisms/spores have been ingested in contaminated food, resulting in an episode of watery diarrhoea. These infections are easily treated with common antibiotics such as penicillin, ciprofloxacin (Cipro, as the media calls it) or tetracycline.
It is important, however, that treatment is administered early on in the infective process and, therefore, anybody who is concerned should see their GP as soon as possible.
Vaccines do exist and it has been reported that the UK government have stockpiles for use if needed. However, they will avoid mass vaccination unless absolutely necessary, due to the potential risks, estimated at a one in a million chance of death and a one in 300,000 chance of serious side effects.
ANTHRAX INFECTION IS NOT KNOWN TO BE SPREAD BY PERSON-TO-PERSON CONTACT.
Action to be taken for suspicious mail/substances
The best action is one of containment. If anybody is suspicious of a package or has opened something containing a suspicious substance it should be handled with extreme care. The package should be gently resealed as best as possible, not moved away from the area and gently placed into a further sealable container, such as a plastic bag. The Police should then be immediately informed and they will assume control of the situation and take the necessary appropriate actions. In the meantime, it would be prudent for personnel to close all windows and calmly leave the immediate area, which should then be sealed off.
If present, local and central air conditioning/ventilation systems should also be isolated as a precaution, as it is likely that the whole building will be evacuated by the Police.
In 1998 a panel of experts on bioterrorism concluded the following on the risk of being killed:-
|Car accident||1: 5,000|
|Terrorist bomb||1: 10s of millions|
|Bioterrorism||1: 100s of millions|
In 2001, 22 cases of cutaneous anthrax occurred, spread through the postal service in the United States. This led to five fatalities.
