Loss of smell is a signal symptom of COVID-19.

  > signal symptom What's the difference between a 'signal symptom' and a normal 'symptom'? Aren't all symptoms signals?

      Nope, a signal symptom is a thing: https://medical-dictionary.thefreedictionary.com/signal+symptom https://medical-dictionary.thefreedictionary.com/signal+symp... "A symptom that is premonitory of an impending condition such as the aura that precedes an attack of epilepsy or migraine."

        By that definition, loss of smell is not a signal symptom for COVID.
      • pstuart 6y ago
        I stand corrected.

    my guess would be some symptoms provide more information for a unique diagnosis than others. Fever, headache, cough are very common symptoms for many things, like the flu, so having them does not single out covid.

    I was reading about this yesterday actually. I think a symptom is reported by the patient, but a sign is noticed by the doctor. I think "signal" meant characteristic or something like that.
