Overview
History
In 90% of the cases, patients presented with ordinary smallpox. Commonly there is a family member, or close contact, with the disease. Ordinary smallpox progresses according to the following periods:[1][2]
Incubation period
- Usually 12 - 14 days
- Asymptomatic
- Noncontagious
Prodrome period
Commonly patients fell very ill during this period.
- Usually 2 - 4 days
- Sometime contagious
- Abrupt onset of fever
- Malaise
- Muscle pain and headache
- Abdominal pain
- Vomiting
Early rash
- About 4 days
- Most contagious stage
- Rash as small red spots in the mouth, tongue and oropharynx
- Rash turns into sores releasing the virus
- Rash appears on the skin, starting on the face, moving towards arms and hands, eventually spreading to the rest of the body within 24-48 hours (centrifugal fashion)
- At this time, fever usually falls and the person feels better
- At the 3rd day of rash, it turns into raised bumps
- At the 4th day of rash, bumps are filled with fluid, with a central depression
- Fever will then raise again, until scabs are formed
Pustular rash
- About 5 days
- Contagious
- Bumps turn into pustules
Pustules and scabs
- About 5 days
- Contagious
- Variable number of pustules, up to a few thousand
- Pustules first forma crust and than a scab
Resolving scabs
- About 6 days
- Contagious, until all scabs have fallen
- Scabs start to fall leaving scars not the skin
- Most scabs will have fallen 3 weeks after start of rash
Resolved scabs
- All scabs have fallen
- Person is no longer contagious
Throughout these stages, the skin lesions were all at the same level of development, among different parts of the body.
Common Symptoms
- Initially in the mouth, that evolves into sores
- Followed by skin rash
Less Common Symptoms
