|WHAT IS IT?
virus, commonly known as smallpox, was eradicated
from the world
in 1977, except for stocks of it kept in two World
Health Organization reference labs.
It is unknown whether it is being held in other
labs in violation of WHO policy.
Smallpox comes in two forms: variola minor or
the more deadly variola major.
HOW DOES IT SPREAD?
The smallpox virus is relatively stable and the
dose required for infection is
small, making it a candidate for aerosol release.
It could then be further
spread by the saliva droplets of infected people.
The incubation period is about 12 days following
exposure. Symptoms include
fever, fatigue and aches, followed by a rash with
lesions and can lead to death
within the first two weeks of the illness.
TREATMENT: No proven treatment at this time.
