The government's scientific advisers will meet later to discuss whether the public should be urged to wear masks to help combat coronavirus. However, hospital bosses are warning that supplies of masks for the NHS could be seriously put at risk if the go-ahead is given for general use. 

Experts are split on the value of masks. The World Health Organization has said there's no evidence to support them being used by the population at large, but other scientists say they can reduce transmission. London Mayor Sadiq Khan, among others, has called for them to become compulsory while travelling in the city. Read what our online health editor has to say on the whole debate. 

The supply of protective kit in general continues, of course, to be a major issue - and we've learned now that dentists are also struggling to get what they need. 

On Monday the UK's deputy chief scientific adviser, Prof Dame Angela Maclean, said the number of new confirmed virus infections was "flattening out", and Chancellor Rishi Sunak said there were "encouraging signs" of progress. Lockdown measures must continue, he insisted though, and to that end, when the House of Commons resumes later the public will see new screens in the chamber to allow MPs to question ministers via video link.

Donald Trump says he will temporarily suspend all immigration to the US to deal with "the attack from the Invisible Enemy", as he calls coronavirus. He also cited "the need to protect the jobs of our GREAT American Citizens". There aren't any other details so far, and BBC North America reporter Anthony Zurcher says like many Twitter directives from the president, the breadth and legality of this one remain to be seen. 

The White House is also continuing to argue the country can begin reopening, despite pleas from state governors to the contrary. Read more on what's behind protests against lockdown across the nation.

Elsewhere, cases in Singapore continue to grow exponentially, mostly among the migrant worker community. France has become the latest country to record more than 20,000 deaths, including those in care homes. But in Italy, there is a small but symbolic ray of light - the number of people officially identified as infected with coronavirus has fallen for the first time.

The economic impact of the pandemic, meanwhile, has been laid bare with news that US oil prices turned negative for the first time. Producers have been paying buyers to take it off their hands because demand has collapsed. Meanwhile, Virgin Australia - the country's second biggest airline - has gone bust.

Everyone wants to know how well their country is tackling coronavirus, but you have to make sure you're comparing the same things when looking at one versus another, as BBC Reality Check explains. That being said, some countries do stand out. Take New Zealand, where the country's success - and Prime Minister Jacinta Ardern's leadership - have won global attention. Other nations might be looking at their unwitting successes - India, for example. There the skies over polluted cities quickly turned an azure blue, and the air unusually fresh, when transport was suspended and economic activity curbed. Could it be the start of a permanent shift?

Debate again surrounds the issue of testing for coronavirus. The Daily Mirror's front page is dominated by pictures of empty test centres - evidence, it says, of the government's "failure" to deliver a promised 100,000 a day by the end of this month. Downing Street sources tell the Daily Telegraph that pledge from Health Secretary Matt Hancock was "arbitrary" and "irrational", and suggest he is being lined up as the "fall guy" for mistakes in the UK virus response. The Guardian reports on splits between ministers over lockdown measures. The chancellor, it says, is among those raising concerns about a lengthy shutdown, but others are far more cautious. Elsewhere, the debate about face masks makes the lead for the Times, which says the World Health Organization may be about to change its position on their use. And the Daily Express backs a call by MPs for a "coronavirus compensation scheme" for the families of NHS workers who have died.
