BEIJING (AP) — New coronavirus cases in the U.S. have surged to their highest level in two months and are now back to where they were at the peak of the outbreak.

The U.S. on Tuesday reported 34,700 new cases of the virus, according to a tally compiled by Johns Hopkins University that was published Wednesday. There have been only two previous days that the U.S. has reported more cases: April 9 and April 24, when a record 36,400 cases were logged.

New cases in the U.S. have been surging for more than a week after trending down for more than six weeks. While early hot spots like New York and New Jersey have seen cases steadily decrease, the virus has been hitting the south and west. Several states on Tuesday set single-day records, including Arizona, California, Mississippi, Nevada and Texas.

Cases were also surging in other parts of the world. India reported a record daily increase of nearly 16,000 new cases. Mexico, where testing rates have been low, also set a record with more than 6,200 new cases.

But China appears to have tamed a new outbreak of the virus in Beijing, once again demonstrating its ability to quickly mobilize vast resources by testing nearly 2.5 million people in 11 days.

In the U.S. state of Arizona, which on Tuesday reported a record 3,600 new infections, hundreds of young conservatives packed a megachurch to hear President Donald Trump’s call for them to back his reelection bid.

As he did at a rally in Oklahoma over the weekend, Trump referred to the virus with a pejorative term directed at its emergence in China.

Ahead of the event, the Democratic mayor of Phoenix, Kate Gallego, made clear that she did not believe the speech could be safely held in her city — and urged the president to wear a face mask. He did not. Trump has refused to wear a mask in public, instead turning it into a red-vs.-blue cultural issue.

Earlier Tuesday, Dr. Anthony Fauci told Congress that the next few weeks are critical to tamping down the surge.

“Plan A, don’t go in a crowd. Plan B, if you do, make sure you wear a mask,” said Fauci, the infectious disease chief at the National Institutes of Health.

In China, an outbreak that has infected more than 200 people in the capital this month appeared to be firmly waning. China on Wednesday reported 12 cases, down from 22 the day before. Beijing reported seven new cases, down from 13.

Officials in Beijing said they tested more than 2.4 million people between June 12 and June 22. That’s more than 10% of the capital’s population of about 20 million.

Authorities began testing people at food markets and in the areas around them. They expanded that to include restaurant staff and the city’s 100,000 delivery workers. China also said it used big data to find people who had been near markets for testing, without specifying how.

The vast majority have tested negative, though one courier delivering groceries from supermarkets tested positive.

A single inflatable mobile lab in one district was capable of conducting 30,000 tests a day, the official Xinhua News Agency said.

South Korea, which successfully tamed its first wave of infections, is seeing another rise. While the first outbreak was centered in its fourth-largest city, the current outbreak is in the Seoul region, where most South Koreans live. Authorities reported 51 cases Wednesday. Its increase of 40 to 50 cases every day over the past two weeks comes amid increased public activity and eased attitudes on social distancing.

In India, with a population of more than 1.3 billion, the densely populated cities of Mumbai and New Delhi have been hardest hit. The country has reported more than 450,000 cases of the virus, including more than 14,000 deaths.

The situation in New Delhi is a rising concern, with the federal government criticizing its poor contact tracing and a lack of hospital beds.

Mexico reported nearly 800 new deaths on Wednesday. The country has recorded more than 190,000 cases and more than 23,000 deaths, although officials acknowledge both are undercounts due to extremely low testing rates. Mexico has performed only about half a million tests, or about one for every 250 inhabitants.

Worldwide, more than 9.2 million people have contracted the virus, including more than 477,000 who have died, according to figures compiled by Johns Hopkins University.
