Loss of smell is an early warning for a COVID-19 infection?

Can a loss of smell be an early warning for a COVID-19 infection? Multiple reports have surfaced, primarily from Europe and the United States, from physicians and ear, nose and throat specialists, of COVID-19 patients complaining of an inability to smell — or anosomia. However, it is not clear whether neurons in the brain that are responsible for recognising various odours are damaged, or whether other cells may be involved. While research on this aspect of the disease is emerging, studies say the loss of smell is different from diminished smell or a lack of perceiving flavour in food when one is afflicted with a cold or stuffy nose.
