(CNN) A New Jersey woman and three of her children died from coronavirus, and two other relatives are in critical condition, a family member said.

Another relative has the virus and is in stable condition, and 19 other family members have been tested, Roseann Paradiso Fodera, a cousin of the mother, told CNN.

Grace Fusco, 73, died after being diagnosed.

A son, Carmine, and daughter Rita, in her mid-50s, died earlier. Another son, Vincent Fusco Jr., died Thursday, Paradiso Fodera said. He was in his early 50s.

"This is an unbearable tragedy for the family," Paradiso Fodera told CNN.
