The 31-year-old Brazilian woman had returned Saturday (6) from a work trip to North Kivu province in eastern Democratic Republic of Congo, and began showing fever and diarrhea Tuesday (9). Transferred from a private hospital to the Emílio Ribas Institute of Infectious Diseases, she remains hospitalized with favorable clinical evolution and receives treatment for acute gastroenterocolitis.

The World Health Organization protocol requires two collections: "A negative result in a sample collected before 72 hours from symptom onset is not sufficient to rule out infection. In this situation, the protocol provides for a new collection after this period. Both samples presented negative results," explained Adriana Bugno, director-general of the Adolfo Lutz Institute.
