"This is a situation that WHO can no longer endorse," outbreak expert Dr. Eric Bertherat wrote to colleagues July 17, 2014.
Metabiota head Nathan Wolfe denied all allegations, stating, "Metabiota's team worked tirelessly, skillfully and at substantial potential danger to themselves to assist when most of the world was still ignoring the problem. We are proud of our team efforts which went above and beyond the call of duty."
Sylvia Blyden, special executive assistant to the president of Sierra Leone, said that, in the early days of the outbreak, Metabiota's response was a mess.
"They messed up the entire region," she stated. Blyden called Metabiota's attempt to claim credit for its work in Africa "an insult for the memories of thousands of Africans who have died."
Doctors Without Borders' emergency coordinator Anja Wolz told AP that she witnessed Metabiota workers visiting the homes of Ebola virus carriers without safety gear and without decontaminating themselves before leaving those areas.
"They didn't even have chlorine with them to wash their hands," Wolz said.
According to WHO, Metabiota was successful in conducting research into an outbreak of Lassa fever some years ago, and the company was hired to help monitor the Ebola outbreak in West Africa based on that work.
