Daniela Trezzi, a 34-year-old nurse who had been treating patients at the San Gerardo Hospital in Monza in the very hard-hit region of Lombardy, reportedly took her own life over the “heavy stress” of testing positive and possibly spreading it to others and after spending a couple of weeks at home sick, reports TMZ.

Her hospital’s general manager said she had been home since March 10, but was not under surveillance. Her death is under investigation.
