i'm 25 years old and i was diagnosed with impetigo today (july 7th). First i had a painful canker sore on my tongue (july 4th) which made it very painful to eat. Then on july 5th, i woke up and i had an abrasion like thing on my lip and around my noise it was red and crusted yellow around my nostrils. Earlier this afternoon (july 7th), i ended up going to urgent care and the doctor said i had impetigo, and he wrote me up a prescription for antibiotic ointment (Mupirocin Ointment USP, 2%) and sent me on my way.
I still have some questions though!
1.) i read that impetigo is highly contagious. How contagious is it? i always wash my hands after i apply the ointment, and I don't touch the area at all, except when im putting the ointment on.
2.) how long can the impetigo bacteria live outside the body? like on surfaces such as towels or pillow cases?
3.) Do i really have to wash all my towels and pillow cases in hot water?
4.) how long will i be contagious for? i read that after 24 hours after the first treatment, impetigo is no longer contagious, is that true?
5.) I really need to shave my face, is it safe to do that while i have impetigo? I won't shave over the scabs at all, and i'll try my best to make sure the razor doesn't touch the areas. BUT would it be ok if i cleaned off the razors with some 91% or 70% isopropyl rubbing alcohol?
6.) Does 91% or 70% isopropyl rubbing alcohol kill the bacteria that causes impetigo on surfaces? (as in, if i sprayed my bed-sheets, pillow cases, shaving razors, and towels with rubbing alcohol, would it be ok then?
