I mean only people who were tested were considered recovered, whether hospitalized or not. Since here anyone with mild/not too serious symptoms are just being told to stay at home, they are not being tested. So, although they probably had Covid19 and recovered from it, we don't know for sure so they do not factor in the numbers.
Here if anyone is sick at home with flu like symptoms, even just a cold, they are to stay in quarantine for 14 days. That is what is considered a safe time to no longer be contagious.
