How long can smallpox last on surfaces?
The smallpox virus is fragile. In laboratory experiments, 90% of aerosolized smallpox virus dies within 24 hours; in the presence of ultraviolet (UV) light, this percentage would be even greater. If an aerosol release of smallpox occurs, 90% of virus matter will be inactivated or dissipated in about 24 hours.

What was the survival rate for smallpox?
Two forms of the disease are recognized, variola minor with a mortality rate of approximately 1%, and the more common variola major with a mortality rate of 30%. Between 65–80% of survivors are marked with deep pitted scars (pockmarks), most prominent on the face.
Does the smallpox vaccine last for life?
Other live virus vaccines currently used include measles, mumps, rubella, and chickenpox. Smallpox vaccination can protect you from smallpox for about 3 to 5 years. After that time, its ability to protect you decreases. If you need long-term protection, you may need to get a booster vaccination.

So, these guys were facing, if not certain death, something pretty close to that.
Did Amherst's blankets kill Indians?

Though person-to-person transmission usually requires close, prolonged contact (a distance of about six or seven feet for about three hours), there are reported instances of fabric-borne infections among people who worked in smallpox hospitals, doing laundry or changing bed linens.
Is the mortuary virus eradicated?
Even a mortuary worker was infected this way, Dr. Damon said. “The disease is now eradicated, though the virus lives in a freezer,” she said, where it is potentially useful for studying the effectiveness of new drugs or vaccines. Advertisement.
Was the plan to infect enemy tribes actually carried out?
It would be at least theoretically possible, experts at the Centers for Disease Control and Prevention said, though some historians doubt that the plan to infect enemy tribes, which the British general Lord Jeffery Amherst notoriously wrote about in 1763, during the French and Indian War, was actually carried out.

To enhance preparedness in the event of a smallpox emergency, in October 2002 the Advisory Committee on Immunization Practices (ACIP) and the Healthcare Infection Control Practices Advisory Committee (HICPAC) recommended smallpox vaccination for persons designated by the appropriate bioterrorism and public health authorities to conduct investigation and follow-up of initial smallpox cases (ie, smallpox response teams). These teams were to include medical team leaders, public health advisors, medical epidemiologists, disease investigators, diagnostic laboratory scientists, nurses, personnel who would administer smallpox vaccines, and security/law enforcement personnel ( CDC 2003: Recommendations for using smallpox vaccine in a pre-event smallpox vaccination program).
What can be performed for rapid tests for rash?
Laboratories that have at least BSL-2 containment facilities can perform rapid tests for diagnosis of rash illness in patients not considered at high risk for smallpox. Local or state LRN laboratories should be contacted for testing of specimens from patients with a moderate or high risk of smallpox (see "Determining the Likelihood of a Smallpox Diagnosis" in the Clinical Syndromes and Differential Diagnosis section). The most likely alternative agents are VZV and HSV; available rapid tests for these two agents include the following:
