How do you think Covid-19 transmitted, is it really human contact or is there some kind of special operation they use to spread it ?

It's a respiratory infection caused by a virus. Covid is spread by water droplets that people produce when they talk, sneeze and or cough. If you're less then 6 ft away from an infected person (close contact for long periods of time), and neither of you is wearing a face covering, they cough or sneeze on you, you have a good chance of contracting it. 

Covid can make you feel like you have a bad cold, or it could be worse then that. You could end up in a hospital on a breathing machine. Also you don't know who could have the virus, not every one that gets it has signs or symptoms. 

It is a virus. It is spread by people like most other common viruses.

Covid spreads via close contact:

Within 6ft for more than 15minutes (total / not each interaction) during a 24 hour period.
