Corona pandemic has awakened memories of the HI virus, which can lead to immune deficiency disease AIDS, from which over 40 million people have died since the beginning of the epidemic at the end of the 1970s. Marcus Peter Tesch has his piece Patient Zero 1 Dedicated to those who were not seen and heard then and now, the “path institutionalized”, also the “lovelessly spent” or “those who have not died”. This dedication is 35 pages, it also forms the first part of this lyrically built drama, which Sandra Schüddekopf has largely staged in the Theater Drachengasse in Vienna as a polyphonic choir.
