LONDON (Reuters) – Britain’s health minister Matt Hancock said anti-viral drug Remdesivir was probably the most significant development yet in treating COVID-19 patients.

“This is probably the biggest step forward in the treatment of coronavirus since the crisis began,” he told a government news conference on Tuesday.

That followed an earlier announcement that Britain would provide the drug, manufactured by Gilead Sciences, to some patients.
