More tests lead to more "positive results" but fewer and fewer hospitalisations and /or deaths.. odd that.
Why do you think it is odd?
The more tests that are run, the more asymptomatic and pre-symptomatic cases are caught - which hopefully puts those people into quarantine, so that they don't go around spreading the virus further.
Evidence of this is where virus hotspots are found amongst healthy workers, then the rest of the farm/factory/processing plant/school is tested and the virus is found in many young, healthy, asymptomatic workers.
The longer the pandemic continues, the better the treatments become, the more information and research is done, and the quicker people are receiving interventions which then reduce the need for hospitalisations.
Plenty of evidence of this in the medications that are found to be effective, and are hitting the news on a regular basis.
Also, the longer the pandemic continues, the better (some) societies are getting at letting the young and less vulnerable got out and get themselves infected, and pass it around, building up 'community/herd immunity, while simultaneously, the more vulnerable are (hopefully) staying safer and more protected - assuming that the younger ones don't take the virus home and infect their vulnerable nearest and dearest.
Evidence of this is the huge numbers of deaths amongst the vulnerable in the early days, when the virus was imported into care homes by asymptomatic visitors and staff.
Absolutely nothing 'odd' about any of those things.
