The first confirmed case of Ebola has been reported in the United States.
Ebola is a totally different ball game from long-established and controllable diseases that are genetically stable, easily preventable, and already well understood and treatable. Ebola is a lot scarier than malaria, for example, even though malaria currently causes a lot more deaths.
Looking at ebola today is like looking at Amazon.com when it was doing $1 million a year in revenue. Both have had alarmingly good early success, are breathtakingly effective at making money/killing people, nimble and constantly evolving, and just looking to explode in growth.
Looking at malaria today is like looking at Phillip Morris. It’s still a huge company with lots of cash, but already in a saturated market that is likely to decline as people move away from cancer-causing habits, or as campaigns for mosquito nets keep improving.
