red eyes
Red eyes and conjunctivitis are common with many viral infections, and a number of ophthalmologists have now raised increasing concern that red eyes with secretions are common in Corona cases, but this sign can be forgotten because it is not a classic sign of the Corona virus.

brain fog

Doctors are now also warning patients to watch out for weak or phantom odors. If you have likely experienced a distorted odor, such as the smell of something strange and unusual with routine foods/smells without prior cause, it could also be a sign of COVID-19.
shortness of breath
Difficulties in breathing and shortness of breath are common complications associated with a viral infection, and experiencing this may also be a sign that you may have coronavirus without knowing it.
