Hello, do you know what causes common cold?
I'm pretty sure it's a viral infectious disease of the upper respiratory tract.
How long does it take after contracting the virus before it starts showing all it's symptoms? 
As soon as  two days after exposure to the virus. What areas are are being affected?
Yeas please tell me and also when was the disease first identified as a virus?
The neolithic period about 12,000 years ago.
Amazing, thanks for enlightening me about common cold
Be safe occasionally you can develop pneumonia.
