Boris Johnson and Donald Trump talked up potential "game changer" breakthroughs in the scientific fight against coronavirus yesterday as they pushed to fast-track research.
The British Prime Minister said the Government was in talks to buy a test as simple as a pregnancy check that could tell people whether theyhave had Covid-19.
The US president said he was greenlighting two drugs already on the market for other purposes for experimental use in the hope they can treat the virus.
Both men gave updates on the drive to find a vaccine. Johnson said trials in the UK should start within a month. In America, a human trial began this week.
Johnson also said 25,000 tests a day for coronavirus would soon be happening in Britain but suggested the number could one day rise to 250,000.
Efforts are being made across the world to better understand coronavirus, with governments, public institutions and private companies all pushing ahead with research.
Covid-19 has emerged so quickly there is neither a vaccine to give immunity nor treatments that could help those who have caught it.
But at press conferences held a few hours apart, Johnson and Trump struck an optimistic tone respectively on scientific progress.
Johnson said: "We are in negotiations today to buy a so-called antibody test, as simple as a pregnancy test, that can tell whether you have had the disease. It is early days but if it works as its proponents claim, then we will buy literally hundreds of thousands of these kits as soon as practicable because obviously it has the potential to be a total game changer."
The test could better help the government understand the full spread of the virus in Britain and also provide reassurance for those who may have caught it and recovered.
Trump's announcements focused on treatments. He said one drug called chloroquine - usually used for malaria - and another called remdesivir would soon be approved for use.
Both drugs are already approved for other purposes but are not known to work against Covid-19, meaning it is not guaranteed they will prove effective.

"I think it's going to be very exciting," Trump said "It could be a game changer, or maybe not."
Trump said he had ordered the Food and Drug Administration [FDA] to "eliminate outdated rules and bureaucracy" so progress could "rapidly" be made.
He said getting such drugs approved normally took months but the process had been sped up, adding that states would distribute them and prescriptions would be needed.
Dr Stephen Hahn, the FDA commissioner who stood next to Trump during the briefing, offered a note of caution about the chance of a speedy breakthrough.
Dr Hahn said: "What's also important is not to provide false hope. We may have the right drug, but it might not be in the appropriate dosage form right now, and it might do more harm than good."
It is unclear when the drugs will be available or how widely they will be distributed. They are essentially at the testing stage. Johnson also mentioned testing for therapeutic drugs in Britain, saying a coronavirus patient in the country is now involved in a "randomised" trial on potential treatments. As for a possible vaccine, Johnson said one was "rapidly coming down the track".
A Scottish scientist leading a team of researchers in the US also said yesterday one million vaccine doses against coronavirus could be available by the end of the year.
Dr Kate Broderick, 42, works at pharmaceutical giant Inovio in California, which is about to move to human trials and has been doing successful tests on animals.
She said: "We'll have a million doses and even though that sounds a lot, it's really not that many when you spread it out over everybody who wants it - so that's a start."
On testing, Johnson said: "We're massively increasing the testing to see whether you have it now and ramping up daily testing from 5000 a day, to 10,000 to 25,000 and then up at 250,000."
Meanwhile, a powerful antibody that could neutralise the virus has been discovered by scientists at the Diamond Light Source, in Harwell, Oxon, in the blood of a patient who recovered from Sars. Covid-19 shares many of the same features as the older virus.

Vaccines
Moderna
The first human trials of a vaccine to fight coronavirus began earlier this week in Seattle - an unprecedented speed given the genetic code of the virus was only sequenced in January.
Researchers at Imperial College London developed a candidate vaccine within 14 days of receiving the sequence from China. They have been testing it on animals since February 10 and hope to move to clinical trials in the summer.
Measles vaccine
Researchers at the Institut Pasteur, University of Pittsburgh, and biotech Themis are using a measles virus vaccine as a "vehicle" to develop a Covid-19 jab. The same technology has already been used to develop inoculations against Lassa fever and chikungunya virus.
A broad-spectrum antiviral treatment developed for Ebola. It was used to treat the United States' first Covid-19 patient in January, who has now made a full recovery.
Chloroquine
An anti-malaria pill that has been used for more than 70 years and several small trials have already shown its effectiveness.
Lopanivir and ritonavir
A combination therapy used commonly in HIV patients.
