I can't find any reference to "Parvovirus-B6" in the literature or any taxonomy. There is only Parvovirus-B19, the near ubiquitous causative agent of the childhood infection known as fifth's disease. Are you immunocompromised? Has any radical treatment such as convalescent plasma been considered?
And yes it's very common in children with mild symptoms, and in adults it's extremely rare to have any symptoms at all(from what I understand it's actually not well studied how common it is as an infection because the symptoms either don't exist or are the same as normal cold so no one gets tested for it). At the hospital at the specialized infectious diseases unit they told me they have only seen 5 adults with it in the last 10 years and I've been the worst case they had.
>>Are you immunocompromised?
No
>>Has any radical treatment such as convalescent plasma been considered?
Not that I know. I did eventually start recovering so I guess they didn't want to go nuclear.
I hope they publish a case study article as a clinical treatment guide for the next cases.
Your kind of situation exposes one of the current inadequacies of the clinical medical profession: falling through the epidemiological cracks of rare diseases and syndromes. There is a finite amount of evidence-based medical knowledge and an inability to rapidly test and adapt to infinite presentations that don't fit neatly into an "average" common case. Perhaps we need both cheaper lab tests/diagnostic procedures (not Theranos in execution but close to it) and tens of thousands more "detective" MD researchers meeting up with clinical side of the healthcare industry to elucidate the unknowns and the unexplained rather than shrug of patient concerns lacking clear explanations. Lastly, clinical MDs should aim to never forget their roots by publishing more.
