Real life event. My wife's boss went to a holiday dinner last weekend. He and his wife got the sniffles the next day. They work in health care so he had Covid rapid tests at home. POSITIVE! He couldn't come to work. He went to the doctor and had a PCR test. NEGATIVE! They just caught a cold. The government is distributing millions of home tests. I think they will register positive if you have any respiratory virus. Thus making millions of people with colds think they had Covid.
