A 75 year old female presented with complaints of pruritic rashes which started from both arms and have now involved trunk region too in last 4 days. T2DM on OAD HTN on medications Her son also complaint that she had an episode of mild fever too today upon asking by me. I attributed to Viral exanthem and gave symptomatic treatment of Atarax 25mg TDS, Calamine + Aloe Vera Lotion, Tab Azilide 500mg OD to take care of superadded bacterial skin infection. Also advised to take plenty fluids. Please give your valuable comments. I refrained from using oral steroids as patient is already diabetic and secondly, using steroids could further suppress immunity and give space for viral infection.
