A drug people can take at home and normally used to fight infections from parasites is being trialled to help treat covid after "promising results".
Ivermectin is the drug being trialled and participants will be given a three-day course of treatment and then followed-up for 28 days with comparisons drawn against those who have been given standard NHS care.
The principle study, led by the University of Oxford, will look at the efficacy of the treatment which has been used in Latin America and South Africa during the pandemic.

It follows a pilot study that showed the drug could reduce viral load (the total amount of virus a person has inside them) and the length of symptoms in patients with mild Covid-19.
Professor Chris Butler, from the University of Oxford's Nuffield Department of Primary Care Health Sciences, said the study would look to test its efficacy.
He said: "Ivermectin is readily available globally, has been in wide use for many other infectious conditions so it's a well known medicine with a good safety profile, and because of the early promising results in some studies it is already being widely used to treat Covid-19 in several countries.
"By including ivermectin in a large-scale trial like Principle, we hope to generate robust evidence to determine how effective the treatment is against Covid-19, and whether there are benefits or harms associated with its use."
The use of ivermectin has been controversial as there is "little evidence ... to demonstrate that it can speed up recovery from the illness or reduce hospital admission" in large-scale randomised studies, according to Oxford researchers.
The study is part of a wider one which is evaluating treatments that can help people aged over 50 recover more quickly from coronavirus and prevent the need for hospital admission, and ivermectin is the seventh drug to be analysed.
