Here are some facts about how Ebola spreads:WHEN IS EBOLA CONTAGIOUS?Only when someone is showing symptoms, which can start with vague symptoms including a fever, flu-like body aches and abdominal pain, and then vomiting and diarrhea.HOW DOES EBOLA SPREAD?Through close contact with a symptomatic person’s bodily fluids, such as blood, sweat, vomit, feces, urine, saliva or semen. Those fluids must have an entry point, like a cut or scrape or someone touching the nose, mouth or eyes with contaminated hands, or being splashed. That’s why health care workers wear protective gloves and other equipment.The World Health Organization says blood, feces and vomit are the most infectious fluids, while the virus is found in saliva mostly once patients are severely ill and the whole live virus has never been culled from sweat.WHAT ABOUT MORE CASUAL CONTACT?Ebola isn’t airborne.
