What was the cause of Mozart's death?

On December 5, 1791, the world of music lost Wolgang Amadeus Mozart. The mystery of his death was never clarified, and several hypotheses were woven into it. The diagnosis issued by the doctor who certified the death was laconic and imprecise: Hitzigas Friesel Fieber (Death by high fever). Clinically, this is a diagnosis that doesn't explain anything... mysteriously, nobody cared to clarify it. Enigmatic, extremely enigmatic. Among numerous theories, they stand out:

Number One Theory:

Mozart died of "rheumatic fever". According to his medical history, it may be the real cause of his death. The Wochembla magazine in Berlin published on December 12, 1791 a laconic note asserting that Mozart's body was inflamed, a symptom of that disease.

Theory Number Two:

Mozart died poisoned by Antonio Salieri, composer and opera director of the Court of Emperor Joseph II, who was attributed with incurable envy against the musician. Various investigations have shown that this theory is apparently absurd.

Theory Number Three:

Mozart was poisoned with "tofana water" by a Mason brother, member of the Court of Emperor Joseph II. "Tofana water" was a mixture of water and arsenic, of delayed action, widely used in the eighteenth century for criminal purposes. Franz Hofdemel, the member of the court, was married to Magdalena Hofdemel, an outstanding pianist in Vienna and a student of Mozart. Believing that his wife was in love with Mozart, Hofdemel tried to murder Magdalena (disfigured her face), poisoned the musician, and then committed suicide. This theory, like so many others, lacks more concrete and proven data.

Theory Number Four:

Mozart was assassinated by the repressive apparatus of Emperor Joseph II and later buried in a mass grave, without identification. There were those who affirmed that Mozart's great operatic successes reflected revolutionary ideas, sowing the fear that they could provoke great changes in the political and social order of the time. Another absurd theory, according to several researchers.

But there are several questions regarding Mozart's death that can never be answered... of facts that are true and produce infinite doubts: Why the speed in burying Mozart's body? Why didn't anyone mark the burial site? Why were funerals performed with mysterious haste?
