My wife's first symptoms were headaches and a dry cough. When she lost her sense of smell, there was no doubt. By the way that was early August and she still can't taste or smell a lot of things and others are definitely off. To me I guess the question I'd ask most people who get cavalier about it all is, "Are you willing to go months or a year with no sense of smell and eat food that is tasteless or doesn't taste right?" On the other hand my sister and brother in law are just getting over it, and they had almost no symptoms - both tested positive.
