A fifth known coronavirus patient has died in Louisiana. The patient was the third resident of a single New Orleans retirement community to die from the virus.

Louisiana has 240 diagnosed cases of the new coronavirus as of Wednesday morning, state health officials said Wednesday morning. The majority of the positive tests were in New Orleans.

State officials identified the fifth person to die of coronavirus in Louisiana as a 98-year-old resident of Lambeth House.

Former judge James D. Carriere, 80, died of coronavirus Tuesday. He was also a resident of Lambeth House. The New Orleans retirement home is the site of the state's only known cluster of cases.

"Obviously Lambeth House is, as I understand it, the only known cluster in Louisiana; despite the fact that we have a number of cases it is the only known cluster for coronavirus," Governor John Bel Edwards said Monday. "And that is very, very tragic because it happens to be a facility that houses older individuals and people with underlying health conditions both on the one side that is an assisted living center and the other side which is an independent living."

As of Monday evening, the Lambeth House was the site of 12 known cases of coronavirus.

"While older individuals and those with underlying medical conditions are at greater risk, everyone can become exposed to COVID-19 and must be vigilant to protect their health," state officials said. "According to the [U.S.] Centers for Disease Control and Prevention, some of the serious chronic health conditions include heart disease, diabetes and lung disease."

At least one married couple living in separate parts of Lambeth House has only been able to connect via balcony visits arranged by the staff.

Some nursing home residents have been in protective isolation for over a week.

The state lab has completed 597 tests, the Louisiana Department of Health said at 9:30 a.m. Wednesday. Commercial lab tests -- which this week have become much more widely available -- are not included in the total, but their positive results are counted as cases.
