when you touch any object which is
contaminated

anybody's hand he becomes a carrier

when you touch the secretion
ON SOME OBJECT or surface
THEN you TOUCH YOUR NOSE ,EYES OR
MOUTH & pass on GERM TO YOU
When someone has cough or cold

If my nasal secretions are so bad
why I am not sick all the time?
Every ones nose has germs and you live with them but
if put your finger then touch a object it becomes
contaminated if this object is touched by another
