As the novel coronavirus spread through the Bay Area and across California last month, deaths in Santa Clara County rose significantly compared to the same month a year before, adding to concerns that the toll of the virus may be more widespread here than initially believed.

New data released to this news organization shows that deaths recorded by the Santa Clara County Medical Examiner rose 20% in March, compared with March of 2019 — an increase that includes a 17% rise in the number of people who died at home.
