All things being equal, the World Health Organization will declare Nigeria free of Ebola on Monday, after 42 days with no reported cases.
According to Time magazine, the milestone was set for 9 a.m. local time.
Nigeria is, however, not immune to another outbreak as the disease has so far killed 4,500 in neighboring West African country.
“It’s possible to control Ebola. It’s possible to defeat Ebola. We’ve seen it here in Nigeria,” Nigerian Minister of Health Onyebuchi Chukwu told TIME. “If any cases emerge in the future, it will be considered—by international standards—a separate outbreak. If that happens, Nigeria will be ready and able to confront it exactly as we have done with this outbreak.”
For the WHO to declare Nigeria’s Ebola-free, the country had to make it 42 days with no new cases (double the incubation period), verify that it actively sought out all possible contacts, and show negative test results for any suspected cases.
Nigeria had 20 cases of Ebola after a Liberian-American man named Patrick Sawyer flew into Lagos collapsed at the airport. Health care workers treating Sawyer were infected, and as it spread it ultimately killed eight people, a low number next to the thousands of cases and deaths in other countries.
Nigeria’s health system is considered more robust, but there was significant concern from experts that a case would pop up in one of the country’s dense-populated slums and spread like wild fire.
