<s>[INST] my 3yr old granddaughter picked her nose and just had a tiny cut inside a week ago but it has now spread all over her nostril and onto her lip and is brown in colour!  What should I apply or do for her and what is it?  Ive been putting germolene on so far. [/INST] Dear parent, this is most probably a herpes simplex viral infection. you should apply an antiviral ointement 3 times daily as acyclovir . this is contagious so avoid kissing and hugging the child until it resolves </s>
