Spain and Italy have reported their lowest death tolls associated with Covid-19 since mid-March, with the number of deaths Spain from the coronavirus below 100 for the first time in two months.

The Spanish health ministry has said the country's death toll has increased by 87 to 27,650, while the number of confirmed cases edged up to 231,350 from 230,698.

Spain introduced one of Europe's strictest lockdowns on 14 March in a bid to contain the virus, which threatened to overwhelm the country's health service.

As the population has remained largely confined to their homes, the rate of new infections and fatalities has steadily fallen, prompting the government to begin unwinding the lockdown.

Health emergency chief Fernando Simon cautioned however, that the low death tally could be due to delays in reporting at weekends.

Asked at a press conference if health authorities had sufficient resources to deal with current patient levels, he said: "The ministry is gathering reserves, but now there is enough material for current needs."

As the government begins to lift restrictions on movement, authorities are considering extending mandatory mask use on public transport to cover all public spaces.

"There is an ample consensus that we should reinforce the obligatory use of masks," Health Minister Salvador Illa told a news conference.

From tomorrow, inhabitants of the sparsely populated Canary Islands of La Graciosa, El Hierro, and La Gomera, and Formentera in the Balearics, will be able to go for walks at any time of day.

However, in Madrid and Barcelona, which have been particularly badly hit, tougher restrictions will remain in place.

Meanwhile in Italy the daily death toll from the pandemic fell to 145, the lowest figure reported since 9 March.

The number of new cases reported in Italy has fallen to 676 - the lowest such figure reported since 4 March.

The total death toll since the outbreak came to light on 21 February now stands at 31,908, the Civil Protection Agency said. It is the third highest in the world after those of the United States and Britain.

The number of confirmed cases amounts to 225,435, the sixth highest global tally behind those of the United States, Spain, Britain, Russia and Brazil.

People registered as currently carrying the illness fell to 68,351 from 70,187 the day before.
