Answer 1

Viruses don’t cause insomnia and viruses don’t do *anything* on purpose. You’re attributing motive to something that’s not even alive let alone sentient. At any rate, viruses don’t cause insomnia in and of themselves. In the case of covid, it’s theorized that some aspect of the immunize response to the virus causes insomnia, but it could also just be the fact that people who feel unwell might have a hard time sleeping, or that changes in routine often lead to sleep issues.
