What Is the Coronavirus?
Plus: How can I avoid catching it? Is Covid-19 more deadly than the flu? Our in-house Know-It-Alls answer your questions.Though nearly a dozen drugs to treat coronavirus are in clinical trials in China, just one—remdesivir, an antiviral that was in trials against Ebola and the coronavirus MERS—is in full-on trials in the US. Nothing has been approved by the Food and Drug Administration. So a promising drug would be great—and even better, chloroquine isn’t new. Its use dates back to World War II, and it’s derived from the bark of the chinchona tree, like quinine, a centuries-old antimalarial. That means the drug is now generic and is relatively cheap. Physicians understand it well, and they’re allowed to prescribe it for anything they want, not just malaria.
Todaro’s tweet got thousands of likes. The engineer/tech world picked up the idea. The widely-read blog Stratechery linked to Todaro’s Google document; Ben Thompson, the blog’s editor, wrote that he was “wholly unqualified to comment” but that the anecdotal evidence favored the idea. Echoing the document, Thompson wrote that the paper was written in consultation with Stanford Medical School, the University of Alabama at Birmingham medical school, and National Academy of Sciences researchers—none of which is exactly true. (More on that in a bit.) One of Todaro’s coauthors, a lawyer named Gregory Rigano, went on Fox News to talk about the concept. Tesla and SpaceX CEO Elon Musk tweeted about it, citing an explanatory YouTube video from a physician who’s been doing a series of coronavirus explainers. To be fair, Musk wasn’t all-in on the idea absent more data, though he wrote that he’d received a life-saving dose of chloroquine for malaria.
Last year, the BCCDC won a $1.4 million grant from the federal health authority, Health Canada, for a pilot program, led by Tyndall, that will study the effects of giving the Downtown Eastside’s most at-risk drug users a regular allotment of hydromorphone pills (the chemical name for Dilaudid) which they can take home and use instead of buying street drugs.
It’s the definition of “big if true.” Part of the story of Covid-19, of the coronavirus SARS-CoV-2, is that it is novel. Humans don’t have any immunity to it. There’s no vaccine, no drug approved to treat it. But if a drug did exist—if a cheap, easy drug can stave off the worst, ventilator-requiring, sometimes-fatal complications of coronavirus infection, or maybe prevent that infection in the first place, what are we all socially isolating for, like suckers?
That if—as the saying goes—is doing a lot of work. The Covid-19 pandemic is causing, reasonably, a worldwide freak-out as scientists and policymakers race to find solutions, not always competently or efficiently. It’s the kind of thing that rankles the engineer-disruptor mindset. Surely this must be an easily solved problem that’s primarily the fault of bureaucracy, regulation, and people who don’t understand science. And maybe the first two things are true. The third thing, though, is where the risks hide. Silicon Valley lionizes people who rush toward solutions and ignore problems; science is designed to find solutions by identifying those problems. The two approaches are often incompatible .
What happened here, specifically, is that Rigano sought Todaro out. Todaro’s tweet identified Rigano as being affiliated with Johns Hopkins; Rigano’s LinkedIn profile says he’s on leave from a masters degree program there in bioinformatics, and has been an advisor to a program at Stanford called SPARK, which does translational drug discovery—finding new uses and applications for approved drugs. “I have a very unique background at the crossroads of law and science,” Rigano tells me. “I have been working with large pharmaceutical companies, universities, biotechs, and nonprofits in the development of drugs and medical products.” He says those contacts told him about the use of chloroquine against Covid-19 in China and South Korea, so he started reading up on it.
(Johns Hopkins did not return a request for comment; a spokesperson for Stanford Medical School emails: “Stanford Medicine, including SPARK, wasn’t involved in the creation of the Google document, and we’ve requested that the author remove all references to us. In addition, Gregory Rigano is not an advisor with Stanford School of Medicine and no one at Stanford was involved in the study.“)It turns out that people have been pitching chloroquine as an antiviral for years. In the early 1990s researchers proposed it as an adjunct to early protease inhibitor drugs to help treat HIV/AIDS. A team led by Stuart Nichol, the head of the Special Pathogens Unit at the Centers for Disease Control and Prevention, published a paper in 2005 saying that the drug was effective against primate cells infected with SARS, the first big respiratory coronavirus to affect humans. That’s an in vitro test, not live animals—just cells.
