The virus is again surging in parts of the United States, but it’s a picture with dividing lines: ominous figures in the Northeast and Upper Midwest, but largely not in the South.
Experts are unsure what explains the split, which doesn’t correspond to vaccination levels. Some point to warmer weather in the Sun Belt, while others suspect that decreased testing is muddying the virus’s true footprint.
The contours of where the virus is resurgent can be drawn around one figure: states that are averaging about 15 new cases a day for every 100,000 people. The 23 states — including Alabama, Mississippi and Arkansas — that have averaged that or fewer over the past week seem to be keeping cases relatively low, according to a New York Times database. Nationally, the country is averaging 21 new cases per 100,000 people.
In the 27 states above that line, though, things have been trending for the worse. Michigan has the highest surge of all, reporting the most drastic increase in cases and hospitalizations in recent weeks. Illinois, Minnesota and others have also reported worrisome increases.
Nationally, reported cases in the United States are growing again after a steep fall from the post-holiday peak in January. In the past two weeks, new confirmed cases have jumped about 11 percent, even though vaccinations picked up considerably, with an average of 3.2 million doses given daily.
Some Southern states, like Alabama and Mississippi, are lagging in vaccinations. Only about 28 percent of people in each state have received at least one shot, according to a New York Times vaccine tracker. Still, case counts continue to drop in both states.
Health experts say cases are rising in the Northeast and Upper Midwest for several reasons, including pandemic fatigue, the reopening of schools and the resumption of youth sports.
Hospitalizations tend to follow the trend line in cases by a few weeks, and have been rising in some states, most notably in Michigan.
Officials are also concerned about the spread of more contagious virus variants, especially B.1.1.7, first identified in Britain. The variant is now the leading source of new coronavirus infections in the United States, the director of the Centers for Disease Control and Prevention said last week.
Just why those factors might affect some states more than others is hard to pinpoint, experts say.
Dr. David Rubin, the director of PolicyLab at the Children’s Hospital of Philadelphia, said warmer weather in Southern states and California was probably playing a role, because it allows people to gather outdoors, with less risk of transmission.
Some experts say, though, that reduced testing in some states could be obscuring the true picture. Testing in Alabama, for instance, has started to dip, but the share of tests that come back positive has remained high, at 11.1 percent, compared with a nationwide average of 5.1 percent, according to data compiled by Johns Hopkins University.
“People who are symptomatic and go to their provider are going to get a test,” said Dr. Michael Saag, the associate dean for global health at the University of Alabama at Birmingham, but “the desire for people to go get tested just because they want to know what their status is has dropped off dramatically.”
Still, Dr. Saag said, there is probably not a hidden spike in cases in Alabama right now, since hospitalizations in the state remain low.
Britain has now offered vaccinations to everyone in the country age 50 and older, the government announced late on Monday , and is extending its program to another age group, the latest sign that the national rollout is continuing at pace.
On Tuesday, the authorities opened vaccinations to anyone 45 or older, yet the announcement came with small hiccup: the website for the country’s National Health Service crashed for a short time after the younger cohort was invited to book appointments online.
The new step in the country’s vaccine rollout comes as the authorities eased several restrictions in England on Monday after months of stringent lockdowns, with pubs and restaurants opened for drinks and dining outside, and nonessential shops once again opening their doors.
Prime Minister Boris Johnson called the moment a “hugely significant milestone” and in a statement thank those involved with the vaccine rollout. Mr. Johnson said the country was on track to offer all adults a vaccination by the end of July. More than 32 million people across Britain have received their first dose of one of the vaccines, according to government data.
The government said it had also already offered vaccinations to every health or care worker, and to everyone with a high-risk medical condition.
England has also began rolling out the Moderna vaccine, which will be offered as an alternative alongside the Pfizer BioNTech vaccine for those under 30, instead of AstraZeneca’s, which has been the mainstay of Britain’s program so far.
There have been concerns about a possible link between the AstraZeneca vaccine and very rare blood clots, and last week British regulators said an alternative should be provided for younger people. Potential infection still poses much greater risks than any vaccine side effect for all those over 30, they said, and could do so for younger people if cases surged again.
“The Moderna rollout marks another milestone in the vaccination program,” Stephen Powis, the medical director of the National Health Service said in a statement. “We now have a third jab in our armory.”
The vaccination program, he added, “is our hope at the end of a year like no other” as he encouraged people to book their appointments.
India said on Tuesday that it would fast-track the approval of vaccines in use in other countries, a move aimed at rapidly increasing the country’s vaccine supply as it battles what is currently the world’s biggest coronavirus outbreak.
The Indian government said that it would grant emergency authorization to any foreign-made vaccine that had been approved for use by regulators in the United States, the European Union, Britain or Japan, or by the World Health Organization. The move had been recommended by a panel of Indian scientists and eliminates a requirement for drug companies to conduct local clinical trials.
“The decision will facilitate quicker access to such foreign vaccines” and encourage imports of materials that would boost India’s vaccine manufacturing capacity, the government said in a statement.
Earlier on Tuesday, India’s top drug regulator granted emergency approval to Sputnik V, the Russian-made vaccine, adding a third vaccine to the country’s arsenal on the same day that health officials recorded 161,736 new coronavirus infections in 24 hours.
It was the seventh straight day that India has added more than 100,000 cases, according to a New York Times database. Only the United States has seen a faster rise in infections during the pandemic.
India has administered about 105 million domestically produced vaccine doses for a population of 1.3 billion, but it is widely believed that the country needs to scale up inoculations rapidly because other measures have failed to control the virus. Many states have reimposed partial lockdowns and weekend curfews. In the country’s financial hub, Mumbai, health officials are racing to erect field hospitals as facilities report shortages of oxygen, ventilators and coronavirus testing kits.
And there is the risk of a superspreading event with the gathering of millions of Hindu pilgrims for the annual Kumbh Mela festival on the banks of the Ganges River, where the authorities say they are powerless to enforce social distancing.
India’s outbreak is reverberating worldwide as its pharmaceutical industry — which was supposed to manufacture and export hundreds of millions of doses of the AstraZeneca vaccine — is keeping most supplies at home. The approval of the Sputnik vaccine, whose first doses are expected to be available for use in weeks, offers hope that India could speed up its inoculation drive.
But it is unclear at this stage whether India will be able to procure significant quantities of other vaccines, including the Pfizer, Moderna and Johnson & Johnson shots in use in the United States. Major Western nations have accumulated much of the global supply of those vaccines and manufacturers are struggling to meet the surging demand.
India will import millions of Sputnik doses from Russia and then begin manufacturing the vaccine domestically, officials said. More than 850 million doses will be made, with some intended for export, Kirill Dmitriev, chief executive of the Russian Direct Investment Fund, a sovereign wealth fund that has financed the vaccine’s development, said in an interview with India’s NDTV channel.
“India is a vaccine-manufacturing hub and our strategic partner for production of Sputnik V,” Mr. Dmitriev said.
India has more than 13.6 million confirmed coronavirus cases, the second most after the United States, and 171,058 deaths, the fourth highest toll.
In other news around the world:
Japan has begun vaccinating 36 million people over age 65, the first time shots have been made available to the public during the country’s slow vaccine rollout. Officials said that 1,139 people nationwide had received doses on Monday, and that doses to cover all Japanese above the age threshold would reach municipal health facilities by the end of June. Although Japan has weathered the pandemic better than most countries, the pace of its vaccination effort, which until now had only covered 1.1 million frontline medical workers, has sparked public criticism and raised questions about readiness for the Tokyo Summer Olympics in just over three months.
The World Health Organization on Monday evening called on governments to suspend the sale of live wild mammals in food markets to help prevent the emergence of new diseases. “Traditional markets, where live animals are held, slaughtered and dressed, pose a particular risk for pathogen transmission to workers and customers alike,” the agency said in a statement. Animals are the source of more than 70 percent of emerging infectious diseases in humans, it said. Early in the pandemic, Chinese officials suggested that the coronavirus outbreak might have started at a market. But W.H.O. experts said in a report last year that the role of animal markets in the story of the pandemic was still unclear.
ArcLight Cinemas, a beloved chain of movie theaters based in Los Angeles, including the Cinerama Dome in Hollywood, will permanently close all its locations, Pacific Theaters announced on Monday, after the pandemic decimated the cinema business.
ArcLight’s locations in and around Hollywood have played host to many a movie premiere, in addition to being favorite spots for moviegoers seeking out blockbusters and prestige titles. They are operated by Pacific Theaters, which also manages a handful of theaters under the Pacific name, and are owned by Decurion.
“After shutting our doors more than a year ago, today we must share the difficult and sad news that Pacific will not be reopening its ArcLight Cinemas and Pacific Theaters locations,” the company said in a statement.
“This was not the outcome anyone wanted,” it added, “but despite a huge effort that exhausted all potential options, the company does not have a viable way forward.”
Between the Pacific and ArcLight brands, the company owned 16 theaters and more than 300 screens.
The movie theater business has been hit particularly hard by the pandemic. But in recent weeks, the majority of the country’s largest theater chains, including AMC and Regal Cinemas, have reopened in anticipation of the slate of Hollywood films that have been put back on the calendar, many after repeated delays because of pandemic restrictions. A touch of optimism is even in the air as a result of the Warner Bros. movie “Godzilla vs. Kong,” which has generated some $70 million in box office receipts since opening over Easter weekend.
Still, the industry’s trade organization, the National Association of Theater Owners, has long warned that the punishing closures were most likely to affect smaller regional players like ArcLight and Pacific. In March, the Alamo Drafthouse Cinema chain, which operates about 40 locations across the country, announced that it had filed for Chapter 11 bankruptcy protection but would keep most of its locations operational while it restructured.
That does not seem to be the case for Pacific Theaters, which, according to two people with knowledge of the matter, fired its entire staff on Monday.
The reaction to ArcLight’s closing around Hollywood has been emotional, including an outpouring on Twitter.
