I think there is a lot of hope because, in a purely research setting, this is extremely routine. The field of genomics is vast but the protocols are somewhat cheap and well understood. It's always hard to do a trial, and the tools are still often aimed at scientists (who are willing to spend months doing a single novel analysis), not point and click for a clinician. But even some relatively low hanging fruit will be extremely effective I think
A child is born with potential rare genetic disease. They sequence their DNA within 13 hours and come back with a diagonsis in some proportion of cases (they give lots of stats, it's small sample size, maybe 1/4 improved outcomes, maybe 2/3 have immediate change to their care)
Not viral/bacterial but human mutations but this is an inspiring study --- https://pubmed.ncbi.nlm.nih.gov/31019026/ , https://radygenomics.org/2021/13-hours-rady-childrens-instit...
