Did Jimmy Butler commit biological warfare against the Mavericks during the game on 11/24?

Butler was listed as questionable before the Heat win over the Mavs on November 24th due to an illness, but was cleared to play shortly before the game and played 38 minutes.

Following this game, 7 different Mavericks players (!!!) have received illness designations on the injury report.

The very next day vs the Hawks on November 25th, Quentin Grimes missed the game due to illness, while Dereck Lively was ruled out for the second half for illness as well. Kyrie was questionable for the game due to illness but ultimately played.

A few days later on November 27th, Daniel Gafford was also ruled out for an illness.

Naji Marshall missed the second half of the November 30th game vs the Jazz due to an upper respiratory illness, and has been out under the same illness designation ever since. If his own Twitter can be considered a source, he was already feeling under the weather on November 26th, and likely before then as well.

Maxi Kleber missed the December 7th game vs Toronto for, guess what, an illness, and has already been ruled out for the Tuesday NBA cup game vs OKC for the same reason.

Marshall is finally listed as questionable after missing the past 4.5 games, but PJ Washington has been listed as questionable now as well due to illness!

Is Jimmy Butler the new Typhoid Mary? The evidence seems pretty clear.

EDIT: Thanks to the comments, there have been some new developments; Butler may have gotten sick from Joel Embiid during their game on 11/18, who was listed as questionable beforehand due to illness. Butler missed all the games between then and the game vs the Mavs. Embiid himself could've gotten it from Andre Drummond who was fighting illness at least as of 11/13. Whoever gave the NBA plague to Andre Drummond still eludes us.
