Earlier quoted context omitted.
RAI is Italy's state-owned TV channel(s). It's controlled by the party that is governing, and has all the problems of anything that is state-run, including a huge potential for inefficiencies, bureaucracy, and at times corruption. Given the quality level of the "experts" used by the government in this pandemic, I wouldn't give it any credit.
State-run doesn't mean anything... BBC is also state-run. It goes to the reputation of the single journalist. In this case the journalist is just citing Frank Hartig, "Oberarzt der Universitätsklinik Innsbruck" I don't have the knowledge to judge his papers and have an opinion about his credibility, but someone else might: https://www.researchgate.net/profile/Frank_Hartig
This is the hospital you're flown to if something really bad happens while skiing in Tyrol.
