 [ Symptoms ] can you get a cold sore from drinking soda [ Disease ] well maybe if you shared a straw with someone who has ever had a cold sore caused by the herpes simplex virus  then yes even if the person had no active cold sore it is still possible to pick up the virus from them and not necessarily just from the straw    if you shared a glass bottle or can of soda with a person who has hsv then you could get the virus from them the odds of getting a cold sore from a random can bottle or glass of soda that is not a container someone else drank from is very very small if you developed a cold sore after enjoying a frosty beverage it is likely you were exposed to hsv some time before you drank the soda and the two events are not related hope this helps
