What is Anthrax?
Anthrax is a rare but serious infectious disease caused by the bacterium Bacillus anthracis. The bacteria produce spores that can survive in the environment for many years. Anthrax primarily affects grazing animals such as cattle, sheep and goats, although humans can become infected through contact with infected animals or contaminated animal products.
Natural cases of anthrax are uncommon in people. Because the spores can remain dormant for long periods, anthrax has also been studied as a potential biological weapon.
Anthrax does not normally spread from person to person.
Types of Anthrax
The symptoms depend on how the bacteria enter the body.
Cutaneous (Skin) Anthrax
This is the most common form of anthrax worldwide.
Symptoms include:
- Small itchy bump resembling an insect bite
- Development of a painless black ulcer (eschar)
- Swelling around the sore
- Fever in some cases
When treated promptly with antibiotics, cutaneous anthrax has an excellent prognosis.
Inhalation Anthrax
This is the most serious form and occurs after inhaling anthrax spores.
Early symptoms may resemble influenza or a common respiratory illness, including:
- Fever
- Fatigue
- Muscle aches
- Mild cough
After several days, severe breathing difficulties, shock and other life-threatening complications may develop.
Immediate medical treatment is essential.
Gastrointestinal Anthrax
This uncommon form follows consumption of contaminated meat.
Symptoms may include:
- Fever
- Nausea and vomiting
- Abdominal pain
- Bloody diarrhoea
- Severe intestinal infection
Can Anthrax Spread Between People?
Direct person-to-person transmission is extremely rare and is generally not considered a public health concern.
Family members, friends and co-workers of someone diagnosed with anthrax do not usually require antibiotics or vaccination unless they were exposed to the same contaminated source.
Diagnosis
Doctors diagnose anthrax using laboratory testing of blood, skin lesions or other appropriate specimens depending on the type of infection.
If anthrax is suspected, healthcare providers will work with national public health authorities to arrange appropriate testing and confirm the diagnosis.
Treatment
Anthrax can usually be treated successfully when diagnosed early.
Treatment typically includes:
- Appropriate antibiotics
- Hospital care for severe infections
- Supportive medical treatment when required
Self-medicating with antibiotics is not recommended. Unnecessary antibiotic use contributes to antibiotic resistance and may delay proper diagnosis of other illnesses.
Always seek medical advice if exposure to anthrax is suspected.
Vaccination
Anthrax vaccines exist but are not recommended for the general public.
Vaccination is generally reserved for:
- Certain military personnel
- Laboratory workers
- People whose occupations place them at unusually high risk of exposure
If You Receive a Suspicious Letter or Package
While biological threats are extremely uncommon, the following precautions remain sensible if you receive a suspicious package.
Do:
- Stay calm.
- Do not open, shake or empty the package.
- Place it carefully into another container if this can be done safely.
- Leave the immediate area.
- Wash your hands thoroughly with soap and water.
- Notify your building management, employer or local emergency authorities.
- Follow instructions from emergency responders.
Do Not:
- Attempt to clean up spilled powder yourself.
- Use bleach or disinfectants directly on your skin.
- Handle suspicious materials unnecessarily.
- Spread rumours before authorities have assessed the situation.
Many suspicious powder incidents ultimately prove to involve harmless substances.
Recognising Suspicious Mail
While unusual packages rarely involve biological agents, warning signs may include:
- No return address
- Excessive postage
- Incorrect or misspelled names
- Excessive tape or string
- Oily stains or unusual odours
- Excessive weight for the package size
- Protruding wires or foil
- Restrictive markings such as “Personal” or “Confidential”
None of these characteristics alone confirm that a package is dangerous.
Anthrax in Indonesia
Human anthrax remains rare in Indonesia. Sporadic outbreaks occasionally occur among livestock in some regions, and human infections are generally associated with direct contact with infected animals or consumption of contaminated meat rather than intentional release.
Healthcare providers who suspect anthrax will coordinate testing and case management through Indonesia’s public health authorities and designated reference laboratories.
When Should You Seek Medical Attention?
Seek immediate medical advice if:
- You believe you have been exposed to anthrax.
- You develop symptoms after handling potentially contaminated animal products.
- You become ill following confirmed exposure to a biological incident.
- Public health authorities advise you to seek evaluation.
Early diagnosis and treatment greatly improve outcomes.
