YF transmission intensifies in Nigeria

Further to a Dec 17 WHO Disease Outbreak News update on the intensification of yellow fever (YF) transmission affecting all states, there are reports of 13 confirmed YF cases (and three deaths) from Jos North, Bassa, Riyom and Wase in Plateau state. In the update, the WHO notes the elevated risk for spread of the YF virus ‘into densely populated urban areas where preventive mass vaccination campaigns have not been conducted so far’, such as Kano and Lagos. In other YF news, suspected yellow fever cases continue to be reported from Sikasso and Koulikoro regions in Mali, now numbering 41 with five deaths. The WHO assessment places the proximity of the affected regions to the capital Bamako and the Côte d’Ivoire border, plus low immunity and high population movements as presenting ‘a risk of amplification’ which is high on a national level and moderate for the region. Level one travel notices have been issued by the US CDC regarding Nigeria’s ongoing outbreaks of monkeypox and Lassa fever. Read more.
