The UK will send £200m in aid to help developing nations battle coronavirus, APA reports citing BBC.
The money will mean more help for refugee camps - including new hand-washing stations.
International Development Secretary Anne-Marie Trevelyan said boosting fragile health systems overseas would help prevent a "second wave" of infections hitting the UK.
The latest donation brings Britain's total contribution to the global effort to halt the pandemic to £774m.
It makes the UK one of the biggest donors to the worldwide fight against the virus, according to the Department for International Development (Dfid).
Britain's funding will help install new hand-washing stations and isolation and treatment centres in refugee camps, and increase access to clean water for those living in areas of armed conflict, Dfid confirmed.
