MADRID — The coronavirus outbreak hit home today among the well-born and the desperately poor alike as Britain’s Prince Charles tested positive and India’s 1.3 billion people, or nearly one-sixth of the Earth’s population, found themselves under lockdown.

Meanwhile, U.S. lawmakers finally agreed on a mammoth economic relief package, buoying stock markets around the world. The plan would support businesses through the crisis and give households one-time payments of $1,200 per adult and $500 per child.

In Spain, the death toll shot up by more than 700 for a total of over 3,400, eclipsing the number of fatalities in China, where the outbreak began. Spain is now second only to Italy in the number of dead.

“If we are not already at the peak, we are very close,” said Fernando Simon, head of Spain’s health emergency coordination center. “I cannot say that we have reached it.” Even once the numbers crest, it would be “counterproductive” to think about relaxing restrictions anytime soon, he added.

Spanish media reported that 23 residents of a Madrid retirement home died from COVID-19 or symptoms related to the virus. The home’s management said it had been pleading for more staff and supplies, including virus tests, after 55 of its workers had been forced to take medical leave.

Police in Spain also arrested two people for throwing stones and other debris at a convoy of ambulances and police vehicles as 28 elderly people were being transferred from a nursing home with a high number of infections to another facility in their town.

Charles, the 71-year-old heir to the British throne, is showing mild symptoms of the virus and is isolating himself at a royal estate in Scotland, his office said, adding that his wife, Camilla, has tested negative.

Charles “otherwise remains in good health and has been working from home throughout the last few days as usual,” it said.
