Context (Updated with new information based on Q1, Q2)
In an act of war, an advanced, extraterrestrial species has designed the machina plague - an infectious nanobot pathogen - to wipe out the human race. They will release 10,000 nanobots on January 1st, 2017. Every bot will be located inside one nondescript, human host in Haneda Airport, Tokyo. Release will be at local time.
- Bots do not effect the host directly after infection in order to reproduce.
- Health effects occur gradually after required number of bots is reached. Reaching this number may take between 8 and 24 hours after infection. Symptoms reach a sustained peak approx. 30 minutes after the first symptoms occur.
- Plague is both waterborne and airborne, but bots will only reproduce in human blood
- Outside of the bloodstream they will survive for up to 48 hours before losing power and shutting down; they may be revived if re-introduced
- Bots can permeate flesh to reach capillaries
- Bots reproduce using iron, manganese, lead
- Hosts infect the bloodstreams of other humans using fangs
- Hosts may also come in contact with other hosts' skin, or release bots into the air through respiration
- Only humans can be infected, but other animals may be prey to hosts
- Bots coordinate with other hosts' bots in proximity; no attempts to infect hosts occur. This interaction is not "hive-mind" level
- Bots lobotomize the host brain; preserve feral instincts and locomotion
- Bots reroute nutrients inside the body to form fangs, tubes
- Hosts prey on live animals for blood (and for food), replenishing iron supplies, maintaining blood iron
- New red blood cells are made periodically and in abundance
- Bots repair host if injuries are deadly or life span is exceeded
- Typical "pathogen" symptoms are suppressed if possible to avoid suspicion
- Decapitation separates brain from body, meaning no acquiring food; bots eventually become dormant
- Stake through the heart stops blood flow; organs die before bots remove stake, causing eventual death
- Hosts hide from sunlight, which reveals the structures beneath their skin
- Nanobot communication signals can be detected - identifying a host
- Signals can be jammed, making hosts attack each other thinking they're more humans
- Strong EMPS may quarantine large areas as a last resort
The third question in this series:
Assuming the scenario provided in the context is feasible, what measures must humans take to inhibit the spread of the plague; how can this be quarantined effectively? Cures will be discussed in the next question - please just focus on containment here.
Quarantine measures should be feasible, use relatively cheap technology and precautions, and should not integrate curing the disease.
