A mother and two children in New Jersey state died from nCoV, 4 other children in the family also infected.

Grace Fusco, 73, died on March 18, five days after her oldest daughter Rita Fusco-Jackson, 55, died of nCoV infection. Just hours earlier, Grace's eldest son, Carmine Fusco, in Pennsylvania, also passed away.

Grace has 11 children and 27 grandchildren. Because she was infected with nCoV and had to use a ventilator, she did not know the deaths of her two children.

A relative said that four of Grace's other children were also infected and were being treated in a hospital, three of them in critical condition. Nearly 20 relatives are isolated at home and unable to attend their funerals.

Covid-19 seems to have spread in this family from a reunion dinner earlier this month. One person who attended the dinner earlier had close contact with John Brennan, the first citizen of New Jersey state who died of nCoV on March 10.

Judith M. Persichilli, head of the New Jersey state health agency, said the family tragedy is evidence of the dangers of large gatherings, including family reunions, between Covid-19's spread.

"I want to emphasize the importance of raising individual awareness and avoiding small-scale gatherings," Persichilli said during a press conference on Sunday.

Covid-119 has appeared in 176 countries and territories, causing more than 227,000 people infected, more than 9,300 deaths and nearly 86,000 people recover. The US currently records more than 9,400 cases, of which 155 have died. All 50 states and Washington, DC, have been infected.

The number of nCoV infections in the United States is increasing daily, prompting health officials and leaders to take steps to prevent the pandemic. "We are talking about the possibility of a disease that lasts 12-18 months," said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

The two main factors driving the pandemic are asymptomatic people who easily spread viruses and test problems in the United States. Experts are calling on all people, even those who do not feel sick, to stay away from others at least 2 meters and avoid gatherings.
