When someone sneezes (打喷嚏) or coughs, the viruses can travel as far as one meter through the air, so you'd better stand a proper distance while talking to someone who has a cold.

It spreads quickly once tiny beads of fluid enter your body, often from a sneeze, cough, or kiss. There are hundreds of viruses that can cause a cold; you can never build up immunity to all of them.

Do not take an antibiotic for a viral infection like a cold, a cough, or the flu.
