During the pandemic, Ars has done its best to keep you on top of the most important news. But there are definitely gaps in our coverage: small updates to stories we've covered, or news that we've decided wasn't worth the time to report deeply. Focusing on breaking news also limits our opportunity to provide bigger-picture perspective. To make up for this, we're going to try doing a series of Monday updates to help keep you informed.
Current counts: 4.8 million confirmed cases globally (up 1.3 million over last week); 1.5 million of those in the United States (up 350,000 over last week). 320,000 deaths attributed to COVID-19 (up 70,000 over last week); 90,000 deaths in the US (up 10,000 over last week).
Over a month has passed since President Donald Trump announced that he was halting funding for the World Health Organization, a group that has played a leading role in coordinating the international response to the pandemic. Trump's claim was that it helped China cover up the initial spread of SARS-CoV-2, but over the weekend, reports started circulating that the administration was considering restoring some funding to the organization. The restored funds would represent a small fraction of the US' former budget, and details are still being negotiated.
Last month, we also looked at a draft study that had suggested SARS-CoV-2 had generated an enormous number of asymptomatic infections. Unfortunately, that suggestion was based on some highly questionable methodology and statistics and had come in for harsh criticism from the research community. Last week, BuzzFeed obtained an internal Stanford complaint that alleges both research improprieties by the people doing the study and a possible conflict of interest related to the source of funding for the work.
Early on in the pandemic's spread through the United States, there were reports of a single choir practice in which a single infected individual spread the virus to many of their fellow singers. Now, the CDC has looked into the details of that event, and they are impressive. Of the 60 other people present, 52 appeared to develop SARS-CoV-2 infections (32 of those confirmed by testing). The CDC concludes that while "superspreader" events like this are rare, they provide yet another reason why social distancing is critical.
The global pharma and biotech industries are rushing the development of so many potential vaccines that it's difficult to track all of the efforts that are staring trials. But there was some good news announced this morning by a company called Moderna, which is attempting to develop a vaccine that uses RNA to induce a person's own cells to produce proteins normally made by the virus. In a small safety trial involving 45 people, the vaccine produced an antibody response in every participant (although low doses required a booster to reach high levels of production). Many of those tested appear to have antibodies that bind to the virus in a way that blocks it from infecting new cells.
The company expects to start a Phase 3 trial, with far more participants, in July.
And earlier today, a paper came out that suggests we may be having a role in the changes that are popping up in the coronavirus genome as it continues to spread through the global population. Our cells have enzymes that chemically modify RNA bases, in part to defend against viruses such Read More – Source
