WHO rules out hydroxychloroquine trial
The World Health Organisation has abandoned trials of a controversial malaria drug after failing to reduce the death rate of COVID-19 patients.
Scientists said hydroxychloroquine produced poor results despite large-scale testing.
The WHO is now analysing the potential effect of an anti-viral drug which has produced positive early results.
US President Donald Trump informally endorsed the use of the drug when he revealed he took the drug himself.
