Two suspected Ebola cases in Yola, Adamawa State, tested negative after two rounds of testing, according to a Saturday evening NCDC statement reported by Premium Times on 31 October.

The patients had been isolated during the investigation. Reuters had earlier reported the alert while results were pending.

The NCDC says no case is confirmed in Adamawa. The findings concern the two people tested and do not establish an absence of risk across the country.

Ebola in Nigeria: scientific inquiry announced as patient moves to Switzerland

Africa CDC plans a scientific mission to Nigeria to investigate the source of an Ebola infection, Reuters reports on 26 October 2026. The patient was transferred that day to Geneva University Hospitals, according to their statement.

Genetic similarity to the virus in Kenya's first case does not prove direct transmission, Jean Kaseya tells Reuters. The chain of infection remains undetermined.

The Geneva hospitals describe the patient's condition as stable. Her husband, treated as a contact, is isolated in Zurich. The medical transfer does not resolve the epidemiological inquiry.
