"The condition of the girl, according to our services, is improving thanks to her rapid treatment," the minister said, according to the Reuters report. He added, "the sick child and the people who were in contact with her in Kayes were immediately identified and taken care of."
According to the health minister, the patient's blood tested positive for Ebola after she was admitted to a hospital Wednesday evening, the AP notes.
Although the World Health Organization recently declared neighboring Senegal Ebola-free after a single case of the virus there, Guinea is one of three West African countries hit hard by the outbreak.
Since the beginning of the outbreak, the World Health Organization has counted 9,936 confirmed, probable and suspected cases of Ebola in seven countries: Guinea, Liberia, Sierra Leone, Spain, the United States, Nigeria and Senegal.
The vast majority of those cases are in Guinea, Sierra Leone and Liberia. Along with Senegal, the WHO has also determined that Nigeria is now Ebola-free.
There have been 4,877 confirmed deaths in the current outbreak.
Guinea alone has 1,540 cases of the disease and 904 deaths, according to the latest available figures from the WHO.
