Spain’s coronavirus death toll rose by 838 in one day, officials reported on Sunday, its largest increase during the pandemic.

Spain’s total number of coronavirus deaths climbed to 6,528, as the country enters its third week of almost total shutdown to stop the spread of the virus, Reuters reported. The number of infections also jumped by 6,549 overnight to reach 78,797.

Spanish Prime Minister Pedro Sanchez announced Saturday in a television address that all non-essential workers needed to stay home for two weeks between March 30 and April 9. While their salaries would remain the same, these workers would be expected to catch up on lost hours at a later time, according to Reuters.

Unions approved the prime minister’s announcement, while business groups warned the decision would “generate an unprecedented huge impact on the Spanish economy,” the news service noted. It added that the business groups acknowledged they will obey the order.

Traffic typical of a Sunday morning reportedly was absent in Spain's capital, while police asked passengers of buses and cars why they were outside of their residencies.

Spain has the second-highest coronavirus death rate in the world, behind Italy, where 10,023 people have died.

Spain is fourth in the total number of infected individuals, following the U.S, Italy and China, according to data from Johns Hopkins University.

Worldwide, more than 679,900 people have been infected and more than 31,700 deaths have been recorded.
