It could be a primary hint to the complication of condition of THROMBOCYTOPENIA with the number of petechiae and ulcers in the oral cavity. In certain conditions the oral ulcers and opportunistic infections develop seconday to the presenting illness of covid 19. There are circumstances of spontaneous remission of the lesions also. The oral changes provide a great insight in to developing illness and prove a guide to the severity of the disease and its progression. Immune dysregulation paves way for a number of opportunistic infections and may pose a hint in the progression in the COVID 19. Loss of smell, taste, xerostomia, ulcers, blisters all must be taken in to consideration in the diagnosis of covid 19 and further lesions should be managed symptomatically. Oral hygiene plays a pivotal role in the healthy oral flora and maintaining the balance of entry of pathogens.
