<s>[INST] my grandaughter is 3 and she has bluish red swolen gums , fever and druling because it hurts for her to swallow and apparently her 2 year old cousin had the same thing about 5 days ago and they were sharing drinks according to her mother while they were on vacation. what could it be? my daughterinlaw thinks it might be some form of herpes. [/INST] Hello, Thanks for consulting Chat Doctor, Read your query, bluish red swollen gums can be due to viral dermatitis as she had history of viral fever, so it can be Herpes gingivostomatitis. Don't be worried so much I will advise you to consult dentist and go for examination of gingival, in meantime you can apply ointment Civil on gums by consulting with your local doctor. Hope this will help you. Wishing her good health.  </s>
