Who? That's a false, alarmist rumor and the parent reads like a "technothriller", which is probably the wrong way to talk about real diseases that might alarm people. Remember during the Ebola epidemic in West Africa, some people coming to the U.S., including a nurse who was effectively imprisoned, were subject of a public panic that had nothing to do with reality. There was no risk. Ebola, like any disease, is contagious only in certain ways. The U.S. CDC says:
https://www.cdc.gov/vhf/ebola/transmission/index.html
The virus spreads through direct contact (such as through broken skin or mucous membranes in the eyes, nose, or mouth) with:
* Blood or body fluids (urine, saliva, sweat, feces, vomit, breast milk, and semen) of a person who is sick with or has died from EVD
* Objects (such as needles and syringes) contaminated with body fluids from a person sick with EVD or the body of a person who died from EVD
* Infected fruit bats or nonhuman primates (such as apes and monkeys)
* Semen from a man who recovered from EVD (through oral, vaginal, or anal sex)
The Ebola virus CANNOT spread to others when a person shows no signs or symptoms of Ebola Virus Disease (EVD). ... There is also no evidence that mosquitoes or other insects can transmit Ebola virus.
Please don't spread these rumors. EDIT: It also distracts people from the real risks.
