[/INST] Hello. Thanks for writing to us at heallthcaremagicJudging from the information that you have provided I will keep a possibility of a viral exanthem. I would specifically like to rule out Chicken pox, since as you say that the rash is composed of fluid filled lesions. Chicken pox classically presents with red lesions which later on become topped with fluid filled lesions. The lesions of chicken pox are mainly distributed on the trunk, face and proximal extremities. Palms and soles are usually spared. Fever and other systemic symptoms are present. I will suggest that you visit a dermatologist in your region. Your dermatologist after examination would be able to either confirm or rule out chicken pox. Treatment of a confirmed episode of chicken pox is with oral antivirals e.g. acyclovir or val acyclovir. Symptomatic treatment for fever and malaise should be provided with OTC paracetamol and ibuprofen. Regards </s>
