I'm reading Spillover by David Quammen and the Ebola section has an interesting interview with Barry Hewlett, anthropologist.
I'm reading the Italian translation so I'll try to paraphrase...
The traditional practices in Uganda in case of really "bad spirits" require the person under attack to be isolated and the movement between the attacked village and the rest limited.
Cured, if there are any, are to take care of the ill; no sexual contact with the ill is allowed; meat is not to be eaten just smoked or when got bad; traditional funeral practices get suspended...
These practices together with the intervention of the Ugandan government and CDC, Doctors without borders and WHO contributed to isolate and stop Ebola in Gulu, Uganda.
Hewlett argued that we have unfortunately lost our traditional practices tweaked during many years of evolution.
I'd add that this may be contributing to our selfishness and individualism, and helping coronavirus response in some countries...
Also, on the other hand traditional practices may be the cause of death... It depends probably on the rareness of the problem... In case of common problems and practices, like standard childbirth or breastfeeding, the traditional practices were probably able to tweak enough during the years, while the ginecological and neonatal practices in the 70s didn't get decades long proof of effectiveness and are now scaling back towards some traditional practices in the last decades...
The most important message of the book is that if we continue the deforestation and get close to more wild species, we will get more of their deseases.
I guess in time we will also rebuild our traditional practices around the new infections. Cultures that already have that will have an advantage.
