As a result of two patients testing positive for the Marburg virus earlier this month who later died, health authorities in Ghana have now formally verified two cases of the extremely contagious illness.
The World Health Organization stated that tests performed in Ghana returned positive findings on July 10, but that the cases needed to be validated by a laboratory in Senegal (WHO).
The results have been confirmed by further testing at the Institute Pasteur in Dakar, Senegal, according to a statement from the Ghana Health Service (GHS).
GHS said it is taking precautions to lessen the possibility of the virus spreading, including isolating all individuals who have been identified even though so far none of them have shown any symptoms.
The first case was a 26-year-old male who checked into a hospital on June 26 and died on June 27. The second was a 51-year-old male who went to the hospital on June 28 and died the same day, the WHO said, adding that both men sought treatment at the same hospital.
The two patients in southern Ghana’s Ashanti region had symptoms including diarrhoea, fever, nausea and vomiting, before dying in hospital, the WHO said.
This is only the second outbreak of Marburg in West Africa. The first case of the virus in the region was detected last year in Guinea, with no further cases identified.
There have been a dozen major Marburg outbreaks since 1967, mostly in Southern and Eastern Africa.
Fatality rates have varied from 24 percent to 88 percent in past outbreaks depending on the virus strain and case management, according to the WHO.
Marburg is transmitted to people from fruit bats and spreads among humans through direct contact with the bodily fluids of infected people, surfaces and materials, the WHO says.
No treatment yet exists for Marburg, but doctors say drinking water and treating some of the symptoms improve survival rates.
