India’s rapidly worsening coronavirus outbreak is now expanding on a scale beyond any previously measured in more than a year of the pandemic: The health ministry reported 312,731 new infections on Thursday, the most recorded in any country on a single day.

India’s total eclipsed the previous one-day high of 300,669 recorded coronavirus cases, set in the United States on Jan. 8, according to a New York Times database, though differences in testing levels from country to country, and a widespread lack of tests early in the pandemic, make comparisons difficult.

Over the past two months, the outbreak in India has exploded, with reports of superspreader gatherings, oxygen shortages and ambulances lined up outside hospitals because there were no ventilators for new patients.

As cases worldwide reach weekly records, a substantial proportion of the infections are coming from India, a sobering reminder that the pandemic is far from over, even as infections decline and vaccinations speed ahead in the United States and other wealthy parts of the world. India has surpassed 15.6 million total infections, second most after the United States.

The death toll has also begun to climb precipitously.

On Thursday, the Indian government recorded 2,104 deaths, and an average of more than 1,300 people have died of the virus every day for the past week. That is less than the tolls at the worst points of the pandemic in the United States or Brazil, but it is a steep increase from just two months ago, when fewer than 100 people in India were dying daily.

There are signs that the country’s health system, patchy even before the pandemic, is collapsing under the strain. On Tuesday, at least 22 people died in an accident in the central city of Nashik when a leak in a hospital’s main oxygen tank cut the flow of oxygen to Covid-19 patients.

The picture is staggeringly different from early February, when India was recording an average of just 11,000 cases a day, and domestic drug companies were pumping out millions of vaccine doses. More than 132 million Indians have received at least one dose, but supplies are running low and experts warn that the country is unlikely to meet its goal of inoculating 300 million people by the summer.

Critics say Prime Minister Narendra Modi, who imposed a harsh nationwide lockdown in March 2020 in the early stages of the pandemic, failed to prepare for a second wave or to warn Indians to remain vigilant against the virus, especially as more infectious variants began to spread.

Mr. Modi’s Hindu nationalist government has also allowed a massive Hindu festival to take place, drawing millions of pilgrims to the banks of the Ganges River, and his party has held packed political rallies in several states.

“India’s rapid slide into this unprecedented crisis is a direct result of complacency and lack of preparation by the government,” Ramanan Laxminarayan, the director of the Center for Disease Dynamics, Economics and Policy in Washington, wrote in The New York Times on Tuesday.

The hardest-hit region is Maharashtra, a populous western state that includes the financial hub of Mumbai. On Wednesday, the state’s top leader ordered government offices to operate at 15 percent capacity and imposed new restrictions on weddings and private transportation to slow the spread of the virus.

This week, Britain’s prime minister, Boris Johnson, and Japan’s prime minister, Yoshihide Suga, called off plans to visit India. On Thursday, the Australian prime minister, Scott Morrison, said that direct flights from India would be reduced by about 30 percent, and that Australians would be allowed to travel to India only in “very urgent circumstances.”

In an early analysis of coronavirus vaccine safety data, researchers at the Centers for Disease Control and Prevention have found no evidence that the Pfizer-BioNTech or Moderna vaccines pose serious risks during pregnancy.

The findings are preliminary and cover just the first 11 weeks of the U.S. vaccination program. But the study, which included self-reported data on more than 35,000 people who received one of the vaccines during or shortly before pregnancy, is the largest yet on the safety of the coronavirus vaccines in pregnant people.

During the clinical trials of the vaccines, pregnant women were excluded. That left patients, doctors and experts unsure whether the shots were safe to administer during pregnancy.

“There’s a lot of anxiety about whether it’s safe and whether it would work and what to expect as far as side effects,” said Dr. Stephanie Gaw, a maternal-fetal medicine specialist at the University of California, San Francisco.

The new data, Dr. Gaw said, demonstrate that “a lot of pregnant people are getting the vaccine, there isn’t a significant increase in adverse pregnancy effects at this point, and that side effect profiles are very similar to nonpregnant people.”

“I think that’s all very reassuring,” she said, “and I think it will really help providers and public health officials more strongly recommend getting the vaccine in pregnancy.”

Covid-19 poses serious risks during pregnancy. Pregnant women who develop symptoms of the disease are more likely to become seriously ill, and more likely to die, than nonpregnant women with symptoms.

Because of those risks, the C.D.C. has recommended that coronavirus vaccines be made available to pregnant women, though it also suggests that they consult with their doctors when making a decision about vaccination.

The new study, which was published on Wednesday in The New England Journal of Medicine, is based largely on self-reported data from V-safe, the C.D.C.’s coronavirus vaccine safety monitoring system. Participants in the program use a smartphone app to complete regular surveys about their health, and any side effects they might be experiencing, after receiving a Covid-19 vaccine.

The researchers analyzed the side effects reported by V-safe participants who received either the Pfizer or Moderna vaccine between Dec. 14, 2020, and Feb. 28, 2021. They focused on 35,691 participants who said that they had been pregnant when they received the vaccine or became pregnant shortly thereafter.

After vaccination, pregnant participants reported the same general pattern of side effects that nonpregnant ones did, the researchers found: pain at the injection site, fatigue, headaches and muscle pain.

Women who were pregnant were slightly more likely to report injection site pain than women who were not, but less likely to report the other side effects. They were also slightly more likely to report nausea or vomiting after the second dose.

Pregnant V-safe participants were also given an opportunity to enroll in a special registry that tracked pregnancy and infant outcomes.

By the end of February, 827 of those enrolled in the pregnancy registry had completed their pregnancies, 86 percent of which resulted in a live birth. Rates of miscarriage, prematurity, low birth weight and birth defects were consistent with those reported in pregnant women before the pandemic, the researchers report.

“This study is of critical importance to pregnant individuals,” Dr. Michal Elovitz, a maternal-fetal medicine specialist at the University of Pennsylvania, said in an email. “It is very reassuring that there were no reported acute events in pregnant individuals” over the course of the study, she said.

But the report has several limitations and much more research is needed, experts said. Enrollment in the surveillance programs is voluntary and the data are self-reported.

In addition, because the study period encompassed just the first few months of the U.S. vaccination campaign, the vast majority of those enrolled in the pregnancy registry were health care workers. And there is not yet any data on pregnancy outcomes from people who were vaccinated during the first trimester of pregnancy.

“I think we can feel more confident about recommending the vaccine in pregnancy, and especially with pregnant people that are at risk of Covid,” Dr. Gaw said. “But we do need to wait for more data for complete pregnancy outcomes from vaccines early in pregnancy.”

Federal regulators have found many shortcomings at a plant of Emergent BioSolutions in Baltimore.

WASHINGTON — Federal regulators have found serious flaws at the Baltimore plant that had to throw out up to 15 million possibly contaminated doses of Johnson & Johnson’s coronavirus vaccine, casting doubt on further production in the United States of a vaccine that the government once viewed as essential in fighting the pandemic.

The regulators for the Food and Drug Administration said that the company manufacturing the vaccine, Emergent BioSolutions, may have contaminated additional doses at the plant. They said the company failed to fully investigate the contamination, while also finding fault with the plant’s disinfection practices, size and design, handling of raw materials and training of workers.

The F.D.A. has not yet certified the plant, in Baltimore’s Bayview neighborhood, and no doses made there have gone to the public. All the Johnson & Johnson shots that have been administered in the United States have come from overseas.

The report amounted to a harsh rebuke of Emergent, which had long played down setbacks at the factory, and added to problems for Johnson & Johnson, whose vaccine had been seen as a game changer because it requires only one shot, can be produced in mass volume and is easily stored.

The inspection began after routine checks showed that Emergent workers had contaminated at least part of a batch of 13 million to 15 million doses of the Johnson & Johnson vaccine with the harmless virus that is used to make the AstraZeneca shot, which is not yet authorized in the United States.

The F.D.A. findings, based on an inspection that ended on Tuesday, underscore questions raised in reports by The New York Times about why Emergent did not fix problems earlier and why federal officials who oversee its lucrative contracts did not demand better performance.

In statements on Wednesday, the F.D.A., Emergent and Johnson & Johnson all said they were working to resolve the problems at the factory. There was no indication of how long that would take.

BERLIN — State lawmakers in Germany approved a new version of a law on Thursday boosting the federal government’s power to enforce uniform coronavirus lockdown rules. New restrictions are expected in most districts soon after the president signs the bill into law, which could be as early as Thursday afternoon.

The law, which Chancellor Angela Merkel’s cabinet passed last week, is a response to a disjointed virus response by state governments, which previously had the ultimate say in carrying out restrictions. For months, experts have called for a lockdown to control Germany’s surging third wave of coronavirus infections.

Under the law passed by the federal council of states on Thursday, the rules would apply uniformly across the country but would depend on the rate of infection in each district, leading to more severe lockdowns in highly affected areas. There would be a curfew from 10 p.m. to 5 a.m. in districts with more than 100 new infections per 100,000 people in a week. Restaurants would remain closed, and nonessential stores would require an appointment and a negative test result in districts with more than 150 new infections per 100,000 people. Schools would close if 165 new infections per 100,000 were registered.

Germany is currently measuring 161 infections per 100,000 in a week, according to the health authorities, which also counted 29,518 new infections on Wednesday.

As many as 8,000 people, including right-wing extremists and coronavirus deniers, took to the streets in Berlin to protest the measures on Wednesday. Several lawsuits against it have already been announced.

Germany has recorded more than 80,000 deaths so far.

In other developments across the world:

  • Japan’s auto industry group canceled the biennial Tokyo Motor Show, scheduled for the fall, because of rising coronavirus cases, the Kyodo News agency reported. It was the first cancellation in the 67-year history of the event, which drew around 1.3 million people in 2019. Akio Toyoda, the chairman of the industry group and president of Toyota Motor Corp., said at a news conference that “it seems difficult to offer main programs in a safe environment.” The cancellation came as Japan reported 5,291 new infections, the highest daily total in three months. And it raised more questions about plans for the Tokyo Olympics, which organizers have insisted will begin in July even as officials plan to impose emergency measures in Tokyo and other municipalities.

Fully vaccinated baseball fans will be granted their own section at the Los Angeles Dodgers game this weekend against the San Diego Padres.

The set-aside seats, reported by The Los Angeles Times, are part of the many incentives being offered — from doughnuts to beer — to encourage people to get vaccinated against Covid-19. The Miami Heat and the San Francisco Giants have introduced similar sections at their stadiums.

To prove they are fully vaccinated, fans will have to show government-issued I.D. and documentation like a vaccination card, according to the Dodgers’ website. Everyone 16 years and older will have to show proof that at least two weeks have passed since they were fully vaccinated. Fans younger than 16 will be required to show proof of a negative coronavirus test taken within 72 hours before admission.

Face masks will still be required, but social distancing will not. The team said spectators in the sections for the fully vaccinated will be seated directly next to each other.

The game Saturday won’t mark the first time fans have entered Dodger Stadium since the pandemic began. The team’s home opener on April 9 was attended by fans — just not all that many of them. Attendance was capped at around 11,000, about 20 percent of capacity.

In the past week, there has been an average of more than 2,300 daily coronavirus cases in the state, and Los Angeles County has seen an average of 435 daily cases — a 20 percent drop over the past two weeks, according to a New York Times database.

As of Wednesday, more than 40 percent of Californians had received at least one dose of the vaccine, and more than 20 percent had been fully vaccinated.

On April 15, Gov. Gavin Newsom loosened some restrictions in the state, permitting limited outdoor gatherings and live events, depending on a region’s Covid-19 risk level.

New York Road Runners, the club that puts on the New York City Marathon, has announced the return of its first regularly scheduled race since the beginning of the pandemic.

On Thursday, the club said that it would hold the annual New York Mini 10K on June 12. The 10-kilometer, women-only race has been held annually since 1972, with the exception of last year.

“This is our first real table setting,” said Kerin Hempel, the organization’s interim chief executive. “It’s starting to feel like ‘OK, we’re back, we’re coming back.’”

This will not be the first race the club has held since the onset of the pandemic.

The organization has held a series of “return to racing” events as pilots starting last fall, allowing very small fields to run with safety protocols in place. Among other measures, the races had temperature checks, staggered starts and different corralling of runners.

Those events, Ms. Hempel said, have given N.Y.R.R. the confidence to move ahead with its first regularly scheduled race since March 2020.

The Mini 10K field will be smaller than in past years, with a cap of 1,200 runners. The race will also have safety protocols, such as requiring runners to mask up at the start and finish. (They will be strongly encouraged to wear masks during the race, too.)

It will be the first time N.Y.R.R. has welcomed elite athletes since the 2019 New York City Marathon, with 25 elite athletes expected at the starting line. The 2019 Mini 10K champion, Sara Hall, will return to defend her title.

The announcement comes as runners look ahead — with cautious optimism — to the return of major road races. Ms. Hempel anticipated the question on the minds of many: What does this mean for the New York City Marathon?

“We’ve been saying the marathon is going to happen,” she said. “It’s more about what it’s going to look like, and how many people we can accommodate on the course.”
