WHAT'S HAPPENING TODAY:

- The Tokyo Olympics have reached a critical phase. Japanese organizers and IOC President Thomas Bach say the games will open July 24 at the $1.4 billion national stadium in Tokyo. But athletes are complaining: They can't train; qualifying events have been canceled; the chaos is sure to favor some over others. Giant questions remain about bringing 11,000 athletes from 200 countries together in four months. Bach has said repeatedly it's too early to announce a final decision.

- Africa's cases of the coronavirus rose above 1,000 on Saturday. Angola announced its first cases, meaning at least 40 of Africa's 54 countries are now affected. Congo reported its first death; Burkina Faso reported two new ones - that country now has the most virus deaths of any country in sub-Saharan Africa. The West African nation also has one of the highest caseloads on the continent with 64. Somalia said it's lifting its ban on international flights for two days so stranded citizens can come home. Angola closed its air, land and sea borders this week. Botswana has suspended international travel by all government employees.

- In London, tourist sites were eerily empty a day after the government ordered the closure of all bars, restaurants, movie theaters and other places where people congregate. Pigeons outnumbered people in the usually bustling Trafalgar Square and Leicester Square. There were long lines outside some supermarkets. Prime Minister Boris Johnson is meeting with supermarket executives over the weekend about how to keep the shelves filled.

- In the U.S., at least 13 states have postponed voting and more delays are possible as health officials warn that social distancing and other measures to contain the virus might be in place for weeks, if not months. Primaries scheduled for Georgia, Ohio, Maryland, Indiana, Louisiana, Connecticut and Kentucky have all been postponed to May or June.

- Outbreaks of the new coronavirus at nursing homes in Washington, Illinois, New Jersey and elsewhere in the U.S. are laying bare the industry's long-running problems. The deadliest single spot in the outbreak so far is at the Life Care Center in the Seattle suburb of Kirkland. Federal investigators believe working conditions - including understaffing and low pay - have been a contributing factor in the 35 deaths to date.

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.

ONE NUMBER:

MORE THAN 220,000: Acting U.S. Homeland Security Secretary Chad Wolf says this is the number of Americans who have been screened at airports while returning to the United States from coronavirus affected countries. Americans returning from virus-affected regions have been routed to one of 13 major airports. Many of them have posted on social media of long waits and crowded conditions with hundreds of people crammed together for hours in packed lines. Some also noted that medical personnel didn't even check to see if they had a fever before letting them into the country. Wolf told "Fox and Friends" on Saturday that medical personnel are, in some cases, simply eyeballing individuals to weed out those who seem obviously ill.
