It is the first time that the Marburg virus has been found in West Africa.
Blood samples taken from two people in the south of the country suggested they had the Marburg virus.
The samples were sent to the Pasteur Institute to confirm the diagnosis, according to the health service. Patrick Kuma-Aboagye said that it was the first time that the Marburg virus had been confirmed in the country.
There is no vaccine or treatment for Marburg, which is very similar to the one that has killed people in West Africa. Its symptoms include high temperature and bleeding.
The statement said that no other cases of Marburg had yet been found in the country.
The World Health Organization declared an outbreak in the country. The WHO regional director for Africa said health authorities have responded quickly and are ready for an outbreak.
Without action, Marburg can easily get out of hand. The World Health Organization is marshalling more resources for the response now that the outbreak has been declared.
There was an outbreak declared over in September 2021.
According to the WHO, there have been previous outbreaks and sporadic cases of Marburg in Africa.
Bats can be carriers of the Marburg virus.
The public is advised to avoid caves inhabited by bat colonies and to cook meat thoroughly before consuming it.
Anyone who has been in contact with sufferers must self-isolated.
People with the viral illness have a high temperature and headaches. According to the WHO, the fatality rate in confirmed cases has ranged from 24% to 88% in previous outbreaks.
