Why do you say that? Am I not permitted to point out limitations of a study that even the authors recognize? I'm all for curing this disease as soon as possible.
None of that above changes the rules of scientific inquiry. Here's some dialogue from a movie about Louis Pasteur made in 1936 and describing the state of things around 1860 (only 76 years earlier):
==========================================================
Dr. Charbonnet: You remember a few years ago, he [Pasteur] was the cause of a slight
controversy on the subject of sour wine.
Napoleon III: Oh, yes, I recall.
Dr. Charbonnet: He claimed to have found little animals in it... infinitesimal beasts.
Napoleon III: But are there such creatures? Do they really exist?
Dr. Charbonnet: Your Majesty, microscopic organisms have long been observed.
They spring into being of their own accord wherever there is putrid matter
or fermentation. They are the result rather than the cause of disease.
By heating wine to certain temperature, Monsieur Pasteur was able to destroy them.
I presume he plans to cure blood poisoning in the same manner:
namely, by boiling our blood.
Napoleon III: Heaven forbid.
Dr. Charbonnet: It's not unlikely, I assure you.
Napoleon III: But, I won't have it, Charbonnet. I won't tolerate such practices.
We're not living in the Middle Ages.
This is France... Paris... the nineteenth century.
Empress Eugenie: I think Monsieur Pasteur should be allowed to defend himself.
Dr. Charbonnet: But, your Majesty...
Empress Eugenie: I, too, have read the pamphlet, Doctor Charbonnet.
It said nothing about boiling blood - merely to boil the instruments
that you surgeons use.
Dr. Charbonnet: Your Majesty, if I did anything so absurd as to boil my instruments
or scrub my hands, they'd think I was a witch doctor resorting to charms
and laugh me out of the hospital.

On 9 October 1676, van Leeuwenhoek reported the discovery of micro-organisms. Yet the damage they can do wasn't accepted for another 84 years.
Science is hard.
I am not denying the virus I am calling bullshit on the huge media over hype.
People die from viruses.
