Interesting comments from a London epidemiologist. Sounds as though it's starting to become a more mild bug like the common cold
“Since the start of May, we have been looking at the top symptoms in the app users and they are not the same as they were,” he said. “The number one symptom is headache, then followed by sore throat, runny nose and fever.” More “traditional” Covid symptoms such as a cough and loss of smell were much rarer now he said, with younger people experiencing much more of a bad cold or “funny off feeling.”
