A useful symptom that has been noticed to occur in Covid-19 positive patients is that of Anosmia or lack of smell.  In fact, some doctors believe that it one of the earliest symptoms that indicate an infection of the Covid-19 virus.  The Royal College of Surgeons of England noted data from multiple countries where patients developed anosmia commonly, in Germany 2 out of 3 patients were noted to have it.  An article in MedPage Today discusses these findings.

The American Academy of Otolaryngology (ENT) recommends that this early warning symptom may be a way to help screen patients.  The screening tool is called the “Online Covid-19 Anosmia Screening Tool” an can be used by any healthcare provider to help collect a database of information for these patients.
