User :   My nine and a half month old daughter has a blister like rash on her backside, only a small amount, with a white top to them, also a few on her legs. She also has developed a fever of 38.4. She is a lot sleepier than usual. She seems to be sore when I pick her up. Has gone off her food a bit also. This has just happened over the course of the last 24 hours.
Doctor :   Hi
Doctor :   Since when have you noticed these bliters?
Doctor :   *blisters?
User :   Shes had them since this morning
Doctor :   Is she have other symptoms such as redness, itching burning sensation associated with the rash?
User :   I dont think she's itchy and there is no particular redness only localised around the blister.
Doctor :   How big are these rashes?
User :   They look like a small blister, almost the same sort of thing as hand foot and mouth. She recently had hand foot and mouth about month and a half ago, only a very mild case. On her backside she has a small scattering, about 10 or 12. One on her leg and one on her face. Although the one on her leg and face appear to be fading and she has had those for a few days.
Doctor :   Ok
Doctor :   Before I can explain you about it, I would like to know if your daughter has other symptoms such as chills, shivering, vomiting, loosestools and so on?'
User :   No nothing, she was fine yesterday, the fever came on this afternoon, I gave her some baby panadol which seemed to help. At about 6 this evening I noticed that she felt a lot hotter and gave her some more baby panadol. There has been no vomiting, chills or shivering and her stools seem to be fine for a baby of her age.
Doctor :   Ok
Doctor :   Let me explain to you.
Doctor :   She has symptoms consistent with the features of infection.
Doctor :   Though it looks clear that it either could be a viral infection
Doctor :   or a the blister with secondary bacterial infection
Doctor :   without a physical examination and evaluation
Doctor :   it is a difficult task to differentiate among the two.
Doctor :   A viral infections heal by itself and however a bacterial infection will need antibiotics.
Doctor :   Let me suggest you a few measures which you may follow.
Doctor :   a
Doctor :   1. Continue the use of paracetamol syrup
Doctor :   2. Use local antibiotic creams such as neomycin cream on the affected blisters.
Doctor :   3. Keep the rashes clean and dry.
Doctor :   4. Keep the temperature monitored and if the temperature is above 100 degree F or if she develops chills/shivering
Doctor :   you need to see a doctor for oral antibiotics.
Doctor :   5. Good and nutritious diet with plenty of water needs to be fed.
Doctor :   Do you follow?
User :   Yes, thanks Doctor. How long do you think it would take for the symptoms to dissipate. Should I let it go for another 24 hours and if there's no improvement go and see a doctor for antibiotics?
Doctor :   A viral infection usually fade away in 2-3 days time.
Doctor :   I suggest you to keep a watch on the rashes/blisters
Doctor :   along with monitoring the temperature.
Doctor :   Increase in the size of rashes despite using the neomycin (antibiotic cream)
Doctor :   or presence of discharge from the blister can indicate
Doctor :   secondary infection.
User :   Just out of curiosity, what sort of viral infection causes blisters on a backside or in the genital area of a baby?
Doctor :   This is a sign that you need to consider consulting your doctor.
User :   Could this be a repeat of the hand foot and mouth that she has had previously?
Doctor :   Presence of blister
Doctor :   * I mean blisters are more commonly seen in a bacterial infection
Doctor :   Rashes are more common due to viral infections.
Doctor :   However since you report that there were no significant signs of inflammation such as redness, burning, itching
User :   Okay, could she have caught something off an animal, eg: dog, cat etc. We have a farm with a lot of animals including ponies, sheep etc. Could it be something she caught from them?
Doctor :   Neomycin creams should be useful to you.
Doctor :   It is hard to answer this question without a physical examination.
Doctor :   It either could be an allergic rash which may have got infected
Doctor :   or like I mentioned a viral infection by itself.
User :   Doctor, thank you for answering my questions. I have four other children should I keep them isolated from the baby just in case?
Doctor :   Viral rashes can be contagious.
Doctor :   Moreover there are higher chances of active infection if these rashes are exposed to bare fingers.
User :   So best to have the other children leave the baby alone for a 2 - 3 days?
Doctor :   So, I would suggest you to wait till he is recovered.
Doctor :   Yes.
User :   Thank you for your time doctor, you've put my mind at ease.
Doctor :   Do you have any other query?
Doctor :   Thanks for consulting me.
Doctor :   Bye for now.
