Mpox, the highly infectious disease that used to be called monkeypox, has been declared a public health emergency in Africa by the continent’s top health body.

Scientists from the Africa Centres for Disease Control and Prevention (Africa CDC) say they are alarmed by the speed at which a new strain of Mpox has been spreading.

Since the beginning of the year, more than 13,700 cases and 450 deaths have been recorded in the Democratic Republic of Congo.

The virus, which can cause lesions across the whole body, has spread to other African countries, including Burundi, the Central African Republic (CAR), Kenya and Rwanda.

The declaration of a public health emergency will help governments coordinate their response and potentially increase the flow of medical supplies and aid into affected areas. Africa CDC head Jean Kaseya warned that the disease could spiral out of control if immediate steps were not taken to contain it.

He said the declaration is not merely a formality but a clarion call to action, adding the continent must be proactive and aggressive in its efforts to contain and eliminate this threat.

Health chiefs outside Africa will also be monitoring the situation to assess the risk of the outbreak spreading further.

On 29 July, the European Centre for Disease Prevention and Control said the risk from the Mpox virus was “very low” in Europe.

Mpox spreads from animals to humans and between people through close contact with someone who is infected – including through sex, skin-to-skin contact and talking or breathing close to another person.

It can cause symptoms such as fever, muscle aches and lesions across the body. If left untreated, Mpox can be deadly.

There are two main strains of the virus known to exist. The milder one caused the global outbreak in 2022 that affected Europe, Australia, the US and many other countries – and was mainly spread through sexual contact.

The second more deadly strain, endemic in central Africa, is behind the recently discovered variant in DR Congo.

Three vaccines exist but only people at risk or who have been in close contact with an infected person are usually able to have it.

Dr Kaseya said there were plans to secure about 10 million doses to limit the spread of the disease in Africa.
