The World Health Organization (WHO) says plans by the Africa CDC to have the power to declare public health outbreaks within Africa require further discussion.

The health body says that such a pronouncement will likely lead to confusion and have a huge impact on trade and travel.

The Africa CDC says its push for a stronger role will help it contain the spread of diseases much faster.

Currently, only WHO Director-General Tedros Adhanom can declare a public health emergency of international concern.

The Africa CDC wants to focus on Africa alone.

The head of WHO’s regional office for Africa, Matshidiso Moeti, says such a declaration could trigger huge implications on African countries.

She cited last year's emergence of the Omicron variant of Coronavirus that saw western nations isolate the continent through travel bans on African countries that had detected the variant.

"WHO believes a careful reflection on the interfacing between the declaration of a public health emergency of continental security and the global process would be of benefit," Dr Moeti said in a statement.

Earlier this year, Malawi and Mozambique declared wild polio virus outbreaks following the death of two children in the two southern African countries.

And in May, Sierra Leone also declared an outbreak of anthrax.
