It's a coronavirus, which is a cold. Flu is different. Colds can get bad and give pneumonia, which is what this cold does to those close to death. That's also why the symptoms are different.

Everyone here who had it has said about the same thing with the symptoms: breathing difficulties, aches, and extreme tiredness.

The flu would be more coughing, sneezing, and snotting.

Similar, but different.
