What causes fever, blisters on mouth and throat and swollen lips?
Patient: 2 of my grandchildren are running low grade fever and have blisters in their mouth and throat with very swollen lips..it started with one child and the second one the next day.We are afraid it might be contagious as well. I Don t know if I have given you enough information. Also we know they did not eat anything unusual. Doctor: Thanks for expressing your concern on HealthCareMagic. There are a number of viral infections that give rise to fevers with rashes, although certain other infections also be causative. The nature of rash can distinguish between them. Based on the information that you have provided, it could be herpes or chicken pox but the information that you have provided is not enough. It would have been best if I could have a direct look but that is not possible. I suggest that you consult a doctor. The infection could be contagious and so I would advise isolation upto the point of time when you consult a doctor. He would also be able to tell you whether it is a simple case of vitamin B deficiency.I hope that answers your query. Feel free to revert back with any further queries if any.
