COVID-19's new symptom:

In England everyone is using a “Coved Symptom Study”, in which infected persons show the consequences or symptoms and thus help researchers get to know this virus.

It is from this app that an analysis of the Royal College of London has revealed that a new side effect of Covid-19 is also the inflammation of language, and can cause ulcers, swellings, and sometimes white spots.

So far this symptom is quite rare, but it has been reported by a growing number of patients who have resulted in coronary contact.
