In my world, there is a virus that causes acquired degreasing body syndrome (also known as ADBS) (sorry, the original French name of this disease is syndrome de dégraissage corporel acquis) (the original language of my story is my native French).
The laconic of this infectious disease is a progressive contagious adipocyte degeneration. It is transmitted by all body fluids (vaginal secretions, sperm, mother-to-child, milk, blood, saliva, vomit, urine, and tears). This disease does not directly kill, however, because people who have it become gaunt, they have an EXTREMELY high risk of the following diseases: both female infertility caused by low oestrogen (amenorrhea) and male infertility caused by a lack of nutriments to make viable spermatozoa, osteoporosis, both myocardial infarction and stroke caused by anaemia, both hypotension (low blood pressure) and cardiac arrythmia (irregular heart beat), and amyotrophic lateral sclerosis (all those causes of death are more common in underweight people).
The virus that causes this pandemic is a retrovirus from the Betaretrovirus genus (to be exact, its direct ancestor is the mouse mammary tumor virus).
So, I wonder if this disease could possibly exist.
