There's an interesting film focused on this topic:

The author traveled through Cameroon and documented, among other things, the realities of having a backlog of dead one must properly bury.

Turns out not everyone can afford putting their deceased relatives in a freezer - especially for extended periods of time, so sometimes the dead are stored in a separate storage area next to the home until the living gather the necessary funds.

Isn't this an own goal when it comes to disease?
