Since the outbreak of the deadly disease similar to Ebola was declared in February, the total of laboratory-confirmed cases has been reduced to nine and probable cases to 20. There have been twenty deaths.
Of the eight new cases, two were reported from the Central African country's Kie-Ntem province, four from the Litoral province and two from Centre-Sur province, the WHO said in a statement.
The WHO said that the areas reporting cases are about 150 kilometers apart, suggesting a wider spread of the disease.
In a statement from WHO Africa Director Matshidiso Moeti, the confirmation of these new cases is a critical signal to scale up response efforts to stop the chain of transmission.
Marburg virus disease is a viral haemorrhagic fever that can have a fatality rate of up to 88 percent, according to the WHO.
Symptoms include fever, fatigue and blood-stained vomit and diarrhoea. There are no vaccines or antiviral treatments approved to treat it.
