Aphthous ulcer associated with Covid-19
Abstract
The mouth plays an important role in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) owing to the fact that both the tongue and salivary glands are conducive environments for the storage and spread of the virus. Various oral lesions have now found to be associated with covid 19. We are going to present a case of 53 year old diabetic female developed oral ulcer 4 days after getting a covid positive report.References
