Some people have the symptom of loosing taste and smell sense but it is not yet confirmed as the key symptom. There are not many cases showing this symptom. Be safe.
It has been reported in several countries and a UK study 2 weeks ago, but most government websites don't mention it yet as a symptom to watch out for. You can google lots of articles about olfactory symptoms and loss of taste a few days after the smell sense is lost. the UK study said it was the first symptom for some but new data comes out daily so all I do is sniff the coffee each morning then smile.
I saw a report from someone who had Covid-19 in which he had the loss of smell and taste, but only about halfway into the illness. A lot of reports include it as a symptom but say it is sort of a harbinger. In this guy's case, it happened after he already knew he was sick.
