Is the Mutant Strain a Better Burglar?

A mutant strain of the novel coronavirus that once seemed trivial has now taken over the globe—but it remains shrouded in mystery.
The mutation’s significance is its location. It impacts the virus’s crucial “spike protein,” which “allows it to enter human cells the way a burglar picks a lock.”
This “G” variant does not appear to make patients sicker, but experiments—which are not yet peer reviewed—found the mutation may make the virus much more infectious.
But unknowns abound. Amid massive demand for answers, researchers face a high-stakes balancing act between expediting their work and ensuring it’s sound.
