For the sake of speculation from a layman; Perhaps the recognition that parasitic infection can infect anyone, anywhere, anytime no matter what status or mental state would be the operative, and that finding out exactly what the proper standards on diagnostic protocol of Parasitic Infection requires, and if misdiagnosed with DP, finding out exactly what the diagnostic protocol on Delusional Parasitosis requires.. thus being faced with proving evidence of negligent physician/s failing egregiously to follow proper standards of protocol, and then proving the many dire consequences suffered as a result, including discovery of infection. Legal route would require strong willed, person or people. Skilled, reputable power attorney/s would know how to obtain correct experts. Consult professional legal expert/s for advise if so inclined. Just another sufferer merely speculating on possible ways to bring awareness to a grave problem so to secure needed changes in protection of people. Too physically weak to further the issue. Perhaps others would like to speculate on ways to effective change.
