No mention of what kind of test was performed. And this article is not alone - most don't bother.
The kind of test matters. A qPCR tests the presence of an active infection. Antibody test determines past exposure.
Each has different expectations for symptoms, communicability, and prognosis.
It's not a lot to ask - just report the kind of test that was done, and do so with in the first two paragraphs. Then let me draw my own conclusions about what the study means.
That's a minimum. Ideally, an article would mention the exact brand of test that was performed. If heterogeneous testing methods were used, report that as well.
If it were an antibody test then I don't think it would be correct to say that they "tested positive for coronavirus", and also it wouldn't make sense to talk about their symptomaticity
