My sister started having rashes on her entire body from past few days. We thought that it was because of any insect-bite. We did pest-control spray in our home. But even then, the rashes are increasing on her body. These are itchy and give her sleepless nights. I read few articles which said that skin rashes have also been found in few COVID patients. We are really scared now as my father also started having same symptoms from past two days. What should we do now? Please advise.
