I have flu symptoms, fever, chills, body aches, some vomiting and am developing a rash all over my body. Im in day 3 of being sick. Is it common to develop a rash with flu?  Does it need to be treated? If my fever goes away and I start feeling better but the rash persists, am I contagious?
Thanks for posting you query to Chat Doctor .your symptoms are suggestive of viral infection.usually such type of infection wean off without any treatment when virus completed its life cycle. Presently I don't know the causative virus but as your symptom suggest it would be a respiratory virus and these are usually transmitted by coughing sneezing and by article used by you so you should keep some preventive measure to limit its spread like keep handkerchief when cough and sneeze, avoid to go in overcrowded places, use separate towel and pillows in home etc. Chances of secondary bacterial infection are higher in such condition, so you should maintain good HY Chat Doctor. Take multivitamin tablet. Tablet paracetamol 750 mg (adult dose) can be taken orally to receive fever and body ache.tablet Pentoprazole20 mg with comparison 10 mg orally for nausea and vomiting two times a day. Hope you would be satisfied with my answer.  Feel free to communicate if any query .regards,
