Kenya has started a 42-day countdown to being officially declared Ebola-free, after the country's last confirmed patient was discharged. For that status to become a reality, no new cases can be recorded during that window.
It is a significant moment for the country, and for the wider region watching closely. Reaching the end of that countdown without incident would mark a full stop on what has been an anxious chapter in Kenya's public health story.
Forty-two days. That is all that stands between Kenya and a declaration the whole continent will be relieved to hear.
