corrected me

And as a parent I really–I remember at the time feeling: well, just come home. I didn’t have the idea it would spread, I didn’t have the idea it would happen in a first-world, incredibly affluent society. And he actually corrected me. He said, no, he thought they were doing a good job, and he was following the advice he was getting, and so forth.
Could you please decipher the following- I can't get the logic.The author sayas that he thought the virus wouldn't spread but his son corrected him ( corrected what?) ? Who was doing a good job?

As I said elsewhere

Your example is from an unedited verbatim report. I suspect it may be done with speech to text software. The whole thing is not easy to read, even for a native.

Added to this, spoken English (or any other language) is filled with errors, non-sequiturs, sudden changes of mind and breaks in the flow, ad lib examples, etc.

to correct someone = to give someone accurate advice/information - as opposed to the idea that they held or stated.

He said that Vladivostock was the capital of Russia - I corrected him [by telling him that it was Moscow].
