10 Critical Smallpox Symptoms You Should Know About
Smallpox was one of the most devastating diseases in human history, eradicated in 1980 through widespread vaccination. However, understanding smallpox symptoms remains crucial for historical context and preparedness against potential outbreaks caused by laboratory samples or bioterrorism. This article will break down the progression of smallpox symptoms, explain how the disease spreads, and address frequently asked questions to help you stay informed.
What is Smallpox?
Smallpox, caused by the variola virus, is a contagious and potentially deadly disease. Historically, it caused severe illness and disfiguring skin rashes. Smallpox spreads through person-to-person contact, respiratory droplets, and contaminated objects.
While the disease no longer exists in the general population, understanding its symptoms and history is vital for global health awareness and biosecurity.
Stages of Smallpox Symptoms
Smallpox symptoms typically progress through distinct stages, starting with flu-like symptoms and evolving into the classic skin rash associated with the disease. Let’s explore each stage in detail.
1. Incubation Period (7-17 Days)
- No symptoms are present during this stage.
- The virus multiplies inside the body, but the infected person does not feel sick.
- Smallpox is not contagious during this phase.
2. Initial Symptoms (2-4 Days)
- High Fever: A sudden rise in temperature, often above 101°F (38.3°C).
- Severe Fatigue: A feeling of extreme tiredness and weakness.
- Headache: Intense pain that may persist for days.
- Body Aches: Muscle pain, particularly in the back and legs.
- Vomiting: Nausea and occasional vomiting.
During this stage, smallpox symptoms mimic the flu, making it challenging to diagnose early. The individual becomes contagious once these symptoms appear.
3. Early Rash (4 Days)
- Red Spots: Small red spots first appear on the tongue and mouth.
- Sores in the Mouth: These spots turn into open sores, spreading the virus into saliva.
- Facial Rash: Red bumps develop on the face, spreading to the arms, legs, and torso.
The rash marks the start of the contagious period, as the sores release large amounts of the virus.
4. Pustular Rash and Scabs (5-10 Days)
- Pustules: The red bumps become raised, round pustules filled with thick fluid.
- Firm to Touch: The pustules feel firm, almost like peas under the skin.
- Scabbing: The pustules begin to form scabs, which eventually fall off.
This stage is highly contagious, as the fluid in the pustules contains large quantities of the variola virus.

Smallpox vs. Chickenpox: How to Tell the Difference
It’s easy to confuse smallpox with chickenpox due to the similarity in skin rashes. However, there are distinct differences:
| Feature | Smallpox | Chickenpox |
|---|---|---|
| Rash Pattern | Concentrated on face and limbs | Starts on the torso, spreads outward |
| Lesion Appearance | All pustules are at the same stage | Pustules are at different stages |
| Severity | More severe and life-threatening | Typically mild |
| Contagious Period | Longer, even after rash appears | Contagious until blisters crust over |
How Smallpox Spreads
Smallpox spreads through:
- Respiratory Droplets: Close, face-to-face contact with an infected person.
- Contaminated Objects: Bedding, clothing, and other personal items.
- Airborne Transmission: Rare but possible in closed environments.
Historical Impact of Smallpox
Smallpox caused significant death and suffering throughout history. Here are some key facts:
- Mortality Rate: 30% of those infected died from the disease.
- Global Eradication: Declared eradicated by the World Health Organization (WHO) in 1980.
- Vaccination: The smallpox vaccine, developed in 1796, was pivotal in eliminating the disease.
FAQs about Smallpox Symptoms
1. What are the first symptoms of smallpox?
The first symptoms include fever, fatigue, headache, and body aches, followed by a rash.
2. Is smallpox contagious during the incubation period?
No, smallpox is not contagious during the incubation period.
3. How long does smallpox last?
The disease typically lasts around 4 weeks, with the rash and scabs taking the longest to heal.
4. Can smallpox come back?
No, smallpox cannot recur naturally since it was eradicated. However, laboratory samples remain for research purposes.
5. What should I do if I suspect smallpox exposure?
While smallpox is unlikely in the modern era, contact healthcare professionals immediately for advice and possible vaccination.
