- Two questions aboutthe history of infectious diseases
-
- 1. How long can (or rather, could) the smallpox virus survive outside a
- living host?
- Context: in a famous incident, General Jeffrey Amherst, commander of the
- British forces in the Colonies during the 1763 Pontiac rebellion, suggested
- to one of his subordinates that smallpox-infected blankets be distributed
- to the rebellious Indians. This is well-documented, but there is no evidence
- that the plan was actually carried out other than the fact that smallpox
- did break out among these Indians some time later. According to a couple of
- Infectious Diseases encyclopedias I checked, smallpox _could_ be transmitted
- via bedding and clothing, but these books were discussing transmission in
- hospitals where it wouldn't take long. Amherst's plan must have required
- several days, I would think (collect the blankets, transfer them to middlemen,
- carry them out to the besieging tribes.) Could the virus have survived in the
- blankets for that long?
- (It is possible, I suppose, that the people carrying the blankets became
- infected themselves and transmitted the disease.)
-
- 2. Has any consensus been reached about whether syphilis originated in
- the New World? Those same encyclopedias were noncommittal on this.
