Flu epidemic

Bill Gates: We are vulnerable to flu epidemic in next decade

Mr Gates, whose foundation invests in improving global healthcare, said the Ebola and Zika crises showed the systems for responding to emergencies are still not strong enough.

He was speaking to Dame Sally Davies, the Chief Medical Officer for England and BBC Radio 4's Today programme guest editor.

She revealed that her department had recently rehearsed a "nasty flu" scenario.
