In brief: Virus

The common cold is transmitted while you are symptomatic, by transfer of the organism nose to hand to hand to nose.
Occasionally respiratory transmission possible. Hand washing, wearing a mask and general cleanliness ok. You need not see a doctor unless getting significantly worse.
