Loss of smell and taste has been anecdotally linked to COVID-19 infections. In a study published April 12, 2020 , researchers at UC San Diego Health report the first empirical findings that strongly associate sensory loss with corona virus infection

The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell&taste follow as other very common initial symptoms.Of those who reported loss of smell&taste, the loss was typically profound. But those who show this also have gr8 recovery rate

Interestingly, the researchers found that persons who reported experiencing a sore throat more often tested negative for COVID-19.

In an effort to decrease risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus
