5 things to know for July 31: Coronavirus, election 2020, economy, stimulus, hong kong

(CNN) We already have the second hurricane of the new Atlantic season. Hurricane Isaias likely will spend the weekend dumping rain in parts of the Caribbean and Florida. Here's what else you need to know to Get Up to Speed and On With Your Day. (You can also get "5 Things You Need to Know Today" delivered to your inbox daily. Sign up here.)

1. Coronavirus

Some people who have never had the coronavirus may still have some immunity to it, which could reduce the severity of an infection. How? A new study found individuals who showed some immunity had T cells that were reactive, possibly from exposure to other strains of coronavirus. (Remember, the current strain is just one of many.) Now, scientists want to know more about the role these T cells play in fighting the disease. Another study about the presence of genetic material from the virus in children has raised questions about whether young kids are more likely to transmit it. That's not exactly encouraging news, with many children in the US headed back to school soon. Of the 15 biggest school districts in the country, 10 will begin the school year with online learning only.

2. Election 2020

President Trump floated the idea of postponing the November presidential election, prompting swift and unequivocal pushback from both sides of the aisle. Trump criticized mail-in voting in a tweet and said, "Delay the Election until people can properly, securely and safely vote???" The bottom line is, he doesn't have the authority to do that. Congress sets the election date. And GOP leaders like Senate Majority Leader Mitch McConnell, House GOP leader Kevin McCarthy and Texas Republican Sen. Ted Cruz made it clear the election has never been delayed and never should be delayed. Many critics see the suggestion, even if it doesn't amount to anything, as a clear threat to the American democratic process. Meanwhile, Trump's campaign canceled a series of ad buys over the next few days to review messaging.

3. Economy

America's big economic comeback is sputtering as coronavirus cases pick back up. The US economy contracted at a 32.9% annual rate from April through June, its worst drop on record, and unemployment claims rose for the second week in a row. The grim economic data caused stocks to sink as newfound uncertainty about the predicted economic rebound grows. Not everyone is feeling the pain, though. Amazon and Apple both posted gains this quarter, and Facebook's stock has risen as socially distanced users flock to the platform. Pandemic-era home cooking regimens have boosted Kraft Heinz's bottom line, too.

4. Stimulus

Three key relief programs have either lapsed or are about to expire as Congress continues to debate the next round of coronavirus aid. The $600 unemployment enhancement ends today. A federal moratorium on evictions ended last Friday, leaving more than 12 million renters at risk for homelessness. And the Paycheck Protection Program, which still has $130 billion intended to help small businesses, is set to expire August 8. It doesn't help that, after several days of negotiations following the Republican Senate stimulus proposal, GOP and Democratic leaders are reportedly no closer to an agreement on what to do next.

5. Hong Kong

Hong Kong's government has barred a dozen candidates from the city's legislative elections in September and says more disqualifications may be coming. The decision has raised even more questions about the integrity of the contest and the democratic freedoms of Hong Kong citizens. The city continues to feel the effects of the new national security law imposed by China at the beginning of the month. Behavior like advocating for Hong Kong independence or self-determination is grounds for election disqualification. Human rights groups and international alliances criticized Hong Kong's candidate crackdown and said it was another example of ongoing political restriction.
