In Ghana, health officials have confirmed two people who died of a hemorrhagic fever in June were infected with the deadly Marburg virus. It’s the first time the virus has been observed in Ghana and just the second outbreak of Marburg in West Africa after a single case was detected in Guinea last year. Marburg is related to the Ebola virus. It circulates among fruit bats and primarily spreads between humans through direct contact with the bodily fluids of infected people. There are no vaccines or therapeutics to treat Marburg infections, which are often fatal.
