“I just know my brother’s fighting for his life,” she said. “It makes you ask yourself — the disabled and the elderly, are they really getting the service that they deserve, that they need?”

The Times has identified more than 2,500 nursing homes and other long-term care facilities across the United States with coronavirus cases. More than 21,000 residents and staff members at those facilities have contracted the virus, and more than 3,800 have died.

Even those figures are an undercount. The Times only included cases that have been confirmed by a state or county government agency or by a long-term care facility. Many states, counties and facilities have declined to provide information or provided partial information. Included in the tally were nursing homes, assisted-living facilities, memory care facilities, retirement and senior communities and long-term rehabilitation facilities.

The Times has tracked hundreds of clusters of coronavirus cases across the country. The 10 deadliest have been in nursing homes and long-term care centers, including the Life Care nursing home in Kirkland, Wash., which was linked to at least 43 coronavirus deaths, and the Soldiers’ Home in Holyoke, Mass., a nursing home for veterans where at least 36 deaths have been linked to the virus. Other long-term care centers in Indiana, Maryland and Massachusetts were each tied to more than 20 coronavirus deaths.

In New York, which has had the heaviest concentration of deaths from the coronavirus, nursing homes have been hit particularly hard, with more than 2,700 deaths at nursing homes and adult care facilities — roughly one in four deaths statewide.

Many homes in New York have had to add refrigerator trucks as temporary morgues, or rely on air-conditioners to keep bodies from decaying because the death toll has overwhelmed funeral homes. Families, barred from visiting since March 13, have complained bitterly about a lack of information coming from the facilities as home administrators scramble to keep enough workers on staff. Few had adequate supplies of masks or gowns, or access to testing.

The facility in Richmond, surrounded by churches, apartments and suburban homes, provides rehabilitation and long-term care in a “modern and tranquil setting,” according to its website. But recently, it has turned into one of the deadliest hot spots for the virus that has killed more than 25,000 people across the country.
