Former Vice President Joe Biden, the Democratic presidential frontrunner, said Sunday he thinks the Democrats may have to have "a virtual convention" later this summer amid the coronavirus pandemic.

"Well, we're going to have to do a convention, may have to do a virtual convention," Biden told ABC's "This Week" days after the Democratic Party postponed the event until mid-August. "I think we should be thinking about that right now. The idea of holding the convention is going to be necessary, but we may not be able to put 10, 20, 30,000 people in one place. That's very possible. Again, let's see where it is."

The number of virus deaths has fallen for the third day in a row in Spain — showing some hope in the hard-hit country where more than 12,400 have died as of Sunday. On Saturday, the country reported 809 news deaths, and on Sunday it reported 674.

While Spain is second only to Italy in number of deaths and behind only the U.S. in number of reported infections, both Italy and Spain have recently seen a slowing of infections after weeks of lockdown.

Despite this, Spanish Prime Minister Pedro Sanchez said on Saturday in an address that he would ask parliament to extend lockdown measures by 15 days until April 26.

In the months before the coronavirus infiltrated the U.S., a 49-year-old inmate began drafting a letter inside the walls of a federal prison in Louisiana. The man, Patrick Jones, had been locked up for nearly 13 years on a nonviolent drug charge. He hadn’t seen his youngest son, then 16, since the boy was a toddler.

He was now writing the judge in the hope of receiving a sentence reduction through the newly-signed First Step Act, which offered relief to some inmates convicted of nonviolent drug crimes.

“My child having his own experience of raising his own child would validate my life experience and give meaning to my existence in this world, because 83582-180 has no meaning,” he wrote, referring to his federal inmate number.

The judge denied the request on Feb. 26, 2020. Twenty two days later, Patrick Estell Jones was dead, the first federal inmate to die of the coronavirus.

Iran recorded 2,483 new cases from the past 24 hours, the country's Health Ministry said Sunday. This brought the total to 58,226 confirmed cases in the worst-hit country in the Middle East. 

While more than 22,000 of those people have recovered, another 151 people died from the respiratory illness in the country bringing the total number to 3,603 which is up by 151 from the day before, the ministry said. 

However, Iran’s president Hassan Rouhani said in a TV address on Sunday that “low-risk” economic activities would resume on April 11, but that schools, universities and religious venues will remain closed until April 19.

Britain's Queen Elizabeth II will urge her subjects to show the same “self-discipline” and “quiet good-humoured resolve” that characterized previous generations in a rare address to the nation about the coronavirus epidemic on Sunday.

The monarch will acknowledge the grief, financial difficulties and “enormous changes to the daily lives” felt by many families during “a time of disruption” in a pre-recorded televised address meant to rally the nation.

"I hope in the years to come everyone will be able to take pride in how they responded to this challenge. And those who come after us will say that the Britons of this generation were as strong as any," the 93-year-old will say, according to extracts released by Buckingham Palace.

Her speech comes as the number of deaths from the respiratory illness in the U.K. climbed over 4,300 on Saturday.

On Palm Sunday, the pandemic has challenged Christian churches around the world to find socially distant ways to begin the Holy Week and to mark the final week of Lent.

Carrie Symonds, fiancee of British Prime Minister Boris Johnson, said she is “on the mend” Saturday, after a week suffering from symptoms of COVID-19. 

“Being pregnant with Covid-19 is obviously worrying,” she wrote on Twitter although she admitted she had not been tested for the respiratory illness. She went on to offer the latest medical guidance to other pregnant women.

Britain's Royal College of Obstetricians and Gynecologists says babies are unlikely to be exposed to COVID-19 during pregnancy, and as of now there is also no data suggesting an increased risk of miscarriage.

Johnson himself tested positive for the virus on March 26 and remains quarantined until further notice.
