In the United States, Michigan has averaged more than 7,000 new cases a day.

Brazil this week became just the third country, after the U.S. and Peru, to report a 24-hour tally of COVID-19 deaths that exceeded 4,000. India hit a peak of almost 127,000 new cases in 24 hours, and Iran set a new coronavirus infection record for the third straight day, reporting nearly 22,600 new cases.

Indian Prime Minister Narendra Modi urged people to get vaccinated, writing in a tweet: "Vaccination is among the few ways we have to defeat the virus. If you are eligible for the vaccine, get your shot soon." More than 90 million Indian health workers and Indians older than 45 have received at least one shot, and 11 million of them have received both doses. But that represents just a small portion of the country's population of nearly 1.4 billion people.

In Brazil, less than 3 per cent of 210 million people have received both doses, according to Our World in Data, an online research site.

South Korea reported 700 more cases, the highest daily jump since Jan. 5. Health authorities were expected to announce measures to strengthen social distancing following a meeting Friday.

In Thailand, which has reported only 95 deaths during the pandemic, health officials reported the country's first local cases of the coronavirus variant first detected in Britain.

The news comes at a time when only 1 per cent of the population has been vaccinated and as Thais prepare to celebrate the traditional Songkran New Year's holiday next week, typically a time of widespread travel.

That variant is more contagious, and the U.S. Centers for Disease Control and Prevention said this week that it is now the most common variant in the United States, raising concerns it will drive infections and cause more people to get sick.

Michigan's infection numbers are second in the nation behind New York. Michigan also has the highest number of new cases per capita, with 1 of every 203 state residents getting diagnosed with COVID-19 between March 31 and April 7, according to data compiled by Johns Hopkins University.

Other Midwestern states have seen troubling signs in recent days, including a school district in Iowa where 127 students and five staff members tested positive for the coronavirus or are presumed positive.

In Massachusetts, where the seven-day rolling average of daily new cases has risen to over 2,100 new cases per day, the Massachusetts Public Health Association called on Republican Gov. Charlie Baker to reinstate public health measures. The group urged Baker to limit indoor dining capacity and other indoor activities, saying the rise in cases and hospitalizations followed Baker's decision to loosen those restrictions.

"We are currently in a race between the vaccines and the variants," Carlene Pavlos, the group's executive director said Thursday. "Without these public health measures, even more innocent lives will be needlessly lost."
