- IDEA 1 OF 8
A deadly virus reached America
Preston tells the true story of a 1989 outbreak of an Ebola-like virus among monkeys in a laboratory building near Washington, DC.
Army and government scientists raced to contain it before it could spread.
- IDEA 2 OF 8
Filoviruses are terrifying
Preston describes Ebola and Marburg, viruses that cause severe bleeding and often death.
He explains why scientists consider them among the most dangerous known. Their sudden and violent effects made them feel like something from a nightmare.
- IDEA 3 OF 8
Teams worked in space suits
Preston describes the military biohazard teams who entered the monkey house wearing protective suits.
Every step carried the risk of infection. The work was slow and tense, since a single tear in a suit could be dangerous.
- IDEA 4 OF 8
Containment has levels
Preston explains the levels of biosafety laboratories, from basic to the highest level for the most dangerous germs.
Strict rules protect workers and the public. Higher levels mean more barriers, so germs have fewer ways to escape.
- IDEA 5 OF 8
A cave held a mystery
Preston describes Kitum Cave on Mount Elgon in Kenya, linked to Marburg infections.
Scientists searched it for the virus's natural host. Finding where a virus lives in nature is a key step in understanding how it spreads.
- IDEA 6 OF 8
The Reston strain spared humans
Preston explains that the Reston virus killed monkeys but did not make the exposed people ill.
This was a stroke of luck. Scientists were relieved, though it showed how little was known about such viruses.
- IDEA 7 OF 8
Outbreaks could go global
Preston warns that air travel could carry deadly viruses quickly around the world.
The book raised public awareness of this danger. A traveller infected in one place could reach a distant city before anyone knew.
- IDEA 8 OF 8
Nature strikes back
Preston suggests that cutting into rainforests brings humans into contact with unknown viruses.
He sees these diseases as a response to human disruption. This is his way of describing how new diseases can emerge from disturbed places.
