The World Health Organisation (WHO) said that some treatments appear to be limiting the severity or length of the Covid-19 disease and that it was focusing on learning more about four or five of the most promising ones, Reuters reported.

“We do have some treatments that seem to be in very early studies limiting the severity or the length of the illness but we do not have anything that can kill or stop the virus,” spokeswoman Margaret Harris told a briefing.

“We do have potentially positive data coming out but we need to see more data to be 100 per cent confident that we can say this treatment over that one,” she added, saying more research was needed and planned.
