A nurse at a Stockton hospital who recently visited New York City has died of COVID-19 complications, and his wife, a registered nurse case manager at Adventist Health Lodi Memorial in Lodi, has tested positive for Covid-19 and she is isolated.

Jeff Baumbach, 57, died Monday in Lodi, the Lodi News-Sentinel reported. He was a nurse St. Joseph's Medical Center of Stockton, a Kaiser Permanente hospital. He helped place incoming Kaiser patients in appropriate care and treatment departments, and he helped train other nurses.

His wife Karen Baumbach has been in quarantine at her home for the past two weeks after testing positive for COVID-19. Friends, neighbors and strangers held a vigil outside her home Wednesday night, filling the street in her neighborhood with vehicles with their headlights on and shining cell phone lights in a show of support.

It’s unknown how the Baumbachs contracted the novel coronavirus that is devastating communities across the United States. They both traveled to New York City in mid-March to visit their youngest son, Karen Baumbach’s mother, Sharleen Leal, told the Lodi News-Sentinel. They returned March 16 and Jeff Baumbach resumed work shortly after. Leal said it’s possible he contracted the virus in New York, on their return flight, in Lodi or at St. Joseph’s Hospital.

New York City is the epicenter of the coronavirus pandemic in the U.S. The city health department reported more than 52,900 cases and more than 1,580 deaths due to COVID-19 as of 9:30 a.m. Friday.
