Eleven days after testing positive, Mr Museveni says he is now “a veteran graduate of the war with that enemy”.

He made his Covid status public on 7 June - his diagnosis was subsequently a subject of widespread debate and speculation across East Africa.

On Sunday, he announced that he had tested negative in a long and wry statement on Twitter.

He urged Ugandans to follow his health strategy by avoiding risk factors such as smoking and alcohol, exercising and eating healthy African food.

Even though the World Health Organization (WHO) has declared Covid over as a public health emergency, it is still a global health threat.
