Some, like Hilda Churchill, who survived both World Wars and the 1918 Spanish flu, and Rafael Gómez Nieto, the last member of the unit that helped liberate Paris, were a part of moments that made history. Many lived outside of the limelight, but were still a huge part of daily life, as children, siblings, parents and grandparents.

In an obituary written about Loretta Mendoza Dionisio, an outgoing and unstoppable woman, her family hoped that she would not simply become a statistic: “We didn’t want her to get lost,” they said.

Wyoming is the only state without a recorded death from the virus.

More than 22,000 people have died of the virus in the United States, but Wyoming has not recorded one fatality, according to a New York Times database.

At least 270 people have tested positive for the virus in the state, mostly around its largest cities, and Gov. Mark Gordon has imposed a series of restrictions, including closures of public schools and bans on gatherings of 10 or more people, that will stay in effect until at least April 30.

The virus has likely infected more people, but testing issues have almost certainly kept the authorities and the public from understanding the full scope of the virus’s spread in Wyoming. The state health officer acknowledged this month that necessary materials were in “very short supply.”

Mr. Trump approved a federal disaster declaration for Wyoming over the weekend, opening a spigot of aid money and marking the first time in U.S. history that a disaster had been declared in every state simultaneously.

“Though Wyoming has not reached the dire situations of some states, this declaration will help us to prepare and mobilize resources when we need them,” Mr. Gordon said last week after he asked Mr. Trump to approve the declaration.
