A desperate race to find medical equipment continues as the World Health Organization warns that the outbreak is accelerating and calls on countries to take strong, coordinated action.

And as virus deaths accelerate in the U.S., President Donald Trump has gone against the advice of scientists and top health experts, claiming he will reopen the country and its ailing economy in weeks, not months.

Here are some of AP’s top stories Tuesday on the world’s coronavirus pandemic.

WHAT’S HAPPENING TODAY:

—A series of missteps at America’s top public health agency created a critical shortage of reliable tests for the coronavirus. Those stumbles at the Centers for Disease Control and Prevention hobbled the federal response as the pandemic spread across the nation.

— The International Olympic Committee announced a first-of-its-kind postponement of the Summer Olympics that were to have been held in Tokyo, bowing to the realities of a coronavirus pandemic that is shutting down daily life around the globe and making plans for a massive worldwide gathering a virtual impossibility.

—Hospitals are looking to test a century-old treatment used to fight off flu and measles outbreaks in the days before vaccines: using blood donated from patients who’ve recovered.

—A Phoenix-area man has died and his wife is in critical condition after the couple took an additive used to clean fish tanks known as chloroquine phosphate, similar to the drug used to treat malaria.

—Some experts don’t rule out a downturn in the United States that rivals the magnitude of the 1930s Depression.

—Chinese authorities plan to end a two-month lockdown of most of coronavirus-hit Hubei province at midnight, as domestic cases of what has become a global pandemic subside. The city of Wuhan, where the virus was first detected in December, is to remain locked down until April 8.

—The virus and the nation’s crashing economy are scrambling the themes both political parties thought would carry them to victory in November. Gone are the hopes of Trump and GOP candidates to run on a strong economy. And Democrats must see if they can attack Trump’s competence when many Americans crave a return to normalcy.

—Low-income families still need food. Homeless people need beds. For decades, American nonprofits have relied on volunteers to help the country’s neediest. Now they aren’t able to show up.

—Confusion rippled through Britain a day after a three-week halt to all non-essential activity to fight the spread of the new coronavirus was imposed. Streets were empty but some subways were full. Hairdressers were closed but construction sites were open.

—In the debut episode of “Ground Game: Inside the Outbreak,” host Ralph Russo talks to News Director for Greater China Ken Moritsugu about the lessons the rest of the world can learn from Asia to stem the spread of COVID-19.

WHAT YOU NEED TO KNOW:

For most people, the virus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The vast majority of people recover.

Here are the symptoms of the virus compared with the common flu.

One of the best ways to prevent spread of the virus is washing your hands with soap and water. The U.S. Centers for Disease Control and Prevention recommends first washing with warm or cold water and then lathering soap for 20 seconds to get it on the backs of hands, between fingers and under fingernails before rinsing off.

You should wash your phone, too. Here’s how.
