As other people said, most viral diseases have a asymptomatic period. What's unique about Coronavirus is that the patient can be infectious during the asymptomatic period. This makes coronavirus so hard to be controlled.
- bryanrasmussen 7y agoMy understanding is that most viruses have some short period of infectiousness before symptoms develop, like the flu https://www.cdc.gov/flu/about/disease/spread.htm https://www.cdc.gov/flu/about/disease/spread.htm https://www.nhs.uk/common-health-questions/infections/how-long-is-someone-infectious-after-a-viral-infection/ https://www.nhs.uk/common-health-questions/infections/how-lo... Coronavirus however has a really long infectious period before symptoms can appear. Which I guess is to its evolutionary advantage and thus unlikely to disappear (just guessing on this part)
