ebola is transmitted by body fluids such as blood mucous and perhaps even sweat by a person who actually has ebola. a zillion medical and non-medical conditions can cause a simple fever so the presence of fever does not mean that (a) you have ebola or (b) that you are contagious.
can you transmit ebola if you have a temperature but no other symptoms. how long after you have a temperature does it take for you to become contagious? can ebola simply be transmitted through sweat sneezing?
