No one on Earth has the resources for such a task; perhaps The Pharma Cartel could but that would be like comitting suicide.
So, we do not have such a study; but anyone with enough motivation on the subject, can browse the development of cities in the last century. Sewer systems, running water and toilets, aqueducts, chlorinacion of potable water, etc.
If these fact are correlated with the gradual reduction in lots of infant/adult infections in parallel with those improvements in hygine, then, just simple common sense will give you the answer. Just look at poor countries that lack hyhiene structures.
Yes, it is not scientific, but I wonder how humans managed before this bias science of ours was "invented" 50 years ago.
