People get sick, especially in autumn. And they infect each other. Reporting that some people working at the lab were sick, without any knowledge about kind of sickness is only going to add fuel to the conspiracy theories.

That's a bad thing only if the conspiracy theory is false. At this point, the theory that the Chinese Communistic Party conspired to cover up a lab leak is not implausible. There are multiple known occurrences of pathogens escaping from laboratories.
Well that depends on your objective. If it's to push a certain narrative, then it's bad if it contradicts that narrative; whether or not it's true is secondary.
