The disease caused by the new coronavirus, known as COVID-19, has now infected nearly 770,000 people. More than 36,000 people have died from the disease.

    The United States has more confirmed cases of infection than any other country. Johns Hopkins University's Coronavirus Resource Center's website said Monday that the U.S. has more than 153,000 confirmed infections, followed by Italy with 100,000 and Spain with 85,000. China has about 82,000.

    Health officials expect the numbers of confirmed infections to rise, as more people will be tested for the virus. Countries around the world are racing to build new hospitals or adding measures to treat new patients.

    A U.S. Navy hospital ship arrived in New York City while the city turned Central Park and other buildings into field hospitals to add spaces. Air Force planes flew patients from France and Italy to Germany and Switzerland to free up intensive care for coronavirus patients on life-support.

    A nursing home official told The Associated Press that sick patients in Spain are dying because they are unable to get into overcrowded hospitals. Healthcare workers expect hospitals will not have enough ventilators -- machines that help patients breathe -- for coronavirus patients needing such treatment.

    In the U.S., the non-profit Society for Critical Care Medicine estimated that as many as 900,000 coronavirus patients could need the machines during the outbreak. The United States, however, has only 200,000. Many of those machines are already being used by patients.

    Last Friday, U.S. President Donald Trump used his emergency power under the Defense Production Act to require that carmaker General Motors make more ventilators.

    In preparation, health officials are examining guidelines from state governments and medical groups on how to use limited resources in emergencies.

    For example, New York state's health department guideline excludes some seriously ill people from receiving ventilators in major emergencies. The guideline also says that age may be considered when deciding which patients would be given a ventilator.

    This week, however, medical experts in Germany said age alone should not be a deciding factor in treatment for COVID-19 patients.

    U.S. hospitals also have to decide how long a patient might need a hospital bed or ventilator and how many more lives the machine could save if it were made available to others. That means doctors could have to make decisions that they have never faced -- whether to take a patient off a ventilator to free it up for others.
    美国医院还必须决定一名患者可能需要住多久院或是上多久呼吸机,以及如果将机器提供给他人使用,可以多挽救多少生命。这意味着医生可能不得不做出他们从未有过的决定 -- 是否将呼吸机从患者身上拿走,用于治疗其他人。

    "I pray for their good judgment and their capacity as they make very difficult choices," said Erik Curren. His 77-year-old father died earlier this month from breathing problems related to the coronavirus at an assisted living home in Florida.

    Nancy Berlinger is with the Hastings Center, a bioethics research institute. She said, "This is a really terrifying decision -- you don't want any doctor or nurse to be alone with this decision."

    Dr. Deborah Birx is leading the U.S. effort in the fight against COVID-19. She noted that there is no evidence yet that a hospital bed or ventilator will not be available for Americans when they need it. Even in New York, she said, beds are still available in intensive care units and a large number of ventilators are not being used.

    But what is happening in many countries has worried American healthcare workers.

    In France and Spain, hospital and nursing home officials say nursing home residents with signs of COVID-19 are not necessarily admitted to intensive care.

    Marc Bourquin of the French Hospital Federation said in hard-hit areas, "they are hospitalized only when there is a chance to save them."

    In northern Italy, Dr. Luca Lorini at the Pope John XXIII hospital compared the treatment of coronavirus patients to the treatment of people waiting for an organ transplant.

    "One heart and 10 people who are waiting for a heart transplant. Who gets the heart? The one who has the greatest chance of living better and longer with that heart," he said.
