As sad as it is, epidemics come and go. As she has risen, so she must fall. But take heart, for the sooner she begins her rest, the sooner the forces that seek to cure her for profit shall proclaim victory and move on to the next big thing.
It may take months, or even years of hidden incubation, but someday she will return upon those same leathery wangs that brought her this time. Her friends, her carriers, her protectors, they are the bats, the brush animals. They sheltered her before, and shall continue to do so.
Of course, there is always the possibility that some survivor may pass along her Love through their own. That she may take root in another population through one who does not repress their sexual desires. Only time and faith will show if this is a viable option.
In any case, hold her close, and let her know how proud you are of her. She achieved tens of thousands of infections, an epidemic that lasted more than a year, and a cult following of those who were unafraid to open their hearts (or veins) to her. Celebrate the life, do not morn for that which has not yet died.
