HOUSTON — A Catholic church in Houston has closed its doors after five of its leaders tested positive for COVID-19, including two priests who had helped celebrate public masses which had resumed earlier this month.

The closure and positive tests come after a priest from Holy Ghost parish, 79-year-old Father Donnell Kirchner, died last week. He was diagnosed with pneumonia, but health officials are determining whether he might have contracted the virus before he died May 13.

Kirchner went to an urgent care clinic and later to a hospital emergency room. But after being released, he went back to the home he shared with members of his religious order, the Archdiocese of Galveston-Houston said Monday in a statement.

Masses at the church had resumed May 2 as part of Gov. Greg Abbott’s plan to reopen the state in phases from coronavirus restrictions. Sunday masses had never exceeded 179 people, or about 20 percent of the church’s seating capacity, the diocese said.

The diocese previously said churches would keep attendance at 25 percent capacity, have people wear masks and enforce social distancing. Church personnel would also sanitize commonly used surfaces such as pews between services.

Members of Kirchner’s religious order are asymptomatic but are being quarantined. The diocese encouraged anyone who attended masses at Holy Ghost to get tested as a precaution.

Texas reported more than 1,200 new COVID-19 cases reported Tuesday as the total cases reported since the state’s first case was reported March 17 neared 50,000 cases. Of those, 22 patients died Tuesday of COVID-19-related illnesses to bring the overall death toll to 1,369, the Texas Department of State Health Services reported. The true number is likely higher because many people have not been tested, and studies suggest people can be infected and not feel sick.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and death.
