Simple rules like not touching dead people or sick people? Simple rules, like not touching dead or sick people, and washing your hands regularly would have helped a lot more than "databases" and "global warning and response systems.
It is not reasonable to expect people to not touch dead or sick people and it is absurd to think that proper hand washing would prevent the transmission of Ebola. Ebola is primarily a caregivers disease because the people most likely to get it are those caring for someone near the end of their life. A person walking around with Ebola is unlikely to spread it to another person. And a person who is near the end of life and severely sick with Ebola is unlikely to be walking around. In most places on Earth, a person with Ebola would go to a hospital when their symptoms were very strong. When there aren't hospitals, though, then it will be family members that will help care for a person who starts to spike a fever and is becoming dehydrated due to the explosive diarrhea or projectile vomiting (or both) that they are having. And, people should care for one another, because most of the time, the symptoms of Ebola are indistinguishable from other common ailments a person might have. For some patients, at the very end of life, there might be other signs that are peculiar to Ebola, such as lesions, but this isn't always the case. But in any case, even in a hospital setting, if a person is projectile vomiting or having explosive diarrhea, then often it is not just simply a matter of properly washing ones hands to prevent infection. Lastly, if when a person dies of such conditions, they are likely covered in their own vomit and excrement and may on occassion even have open lesions on their skin. Properly cleaning the area of a sick person and preparing their body for burial is something that trained professionals with proper equipment should do. But, again, such professional services do not exist throughout much of rural West Africa, and so the job of cleaning, preparing a body, and burying a body falls on shoulders of the members of the family and household.
As Paul Farmer said: "The only formula we’ve come up with is the following: you can’t stop Ebola without staff, stuff, space and systems. And these need to reach not only cities but also the rural areas in which most people in West Africa still live."
