It's the asymptomatic spread that has caused a lot of the problems and concern. People with ebola for example rarely spread it because they become so quickly and acutely ill. But with COVID, you're going about your normal life for days while spreading it unknowingly before symptoms hit (if they even hit at all).

- standardUser 5y agoI used the wrong word! Most data shows people who have a truly asymptomatic infection do not frequently spread the virus. But much if not most of the transmission occurs from infected people while they are pre-symptomatic. Hence the ease of spreading the diseases, and the push by many health agencies to get people with no symptoms to wear masks and social distance in case they are infected but don't know it yet.
