It is highly contagious. But not as much as say, the measles.

  COVID19's main issue is that it takes anywhere from 5 to 14 days before you feel symptoms. During this window, it looks like you're still spreading COVID19 around. Therefore: traditional means of preventing spread (ie: staying home from work and/or school) are ineffective. Measles or Ebola (or plenty of other diseases) have a much smaller window of spreading (because you feel sick sooner).

    What's the latest on asymptomatic spread for covid-19? Last update I had seen was that this wasn't likely. https://www.nature.com/articles/s41467-020-19802-w https://www.nature.com/articles/s41467-020-19802-w

      Asymptomatic is not pre-symptomatic.

        What's the latest information on presymptomatic spreading?

  Is there a human pathogen more contagious than measles? I remember reading this scenario that really gave me a sense of how contagious it is: > The virus can linger in the air for about two hours after a person with measles has left the room. It can infect those who enter the room if they are unimmunized.

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).

    I 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. Here's a couple relatively recent links: https://wwwnc.cdc.gov/eid/article/27/4/20-4576_article https://wwwnc.cdc.gov/eid/article/27/4/20-4576_article https://www.health.harvard.edu/diseases-and-conditions/most-covid-19-cases-are-spread-by-people-without-symptoms https://www.health.harvard.edu/diseases-and-conditions/most-...
