Yellow fever situation update; Lassa fever persists, moves across borders

From the latest WHO regional report on the yellow fever outbreak that began in Sept. 2017, ‘the continuation of the yellow fever outbreak in Nigeria and the rapid increase of the number of cases in Edo State is concerning.’ Almost half of the cases reported in the last three months of the year in Edo were from ‘a rural farming community whose population frequently travels to the nearby state capital, Benin City, with a population of 1.5 million people’. The second phase of a YF vaccination campaign is underway across six states and the Federal Capital Territory according to ReliefWeb.

LASSA fever data for the last week of 2018 revealed another 22 cases from the states of Edo, Ondo, Bauchi and Taraba which takes the yearly total to almost 3,500. A Nigeria Center for Disease Control (NCDC) report states that ‘80% of all confirmed cases are from Edo (44%), Ondo (25%) and Ebonyi (11%) states’. Cases generally peak in the first three months of the year. In north Benin, 15 people have been diagnosed with Lassa fever since mid-December in an outbreak that stemmed from a woman who had contracted the infection in Nigeria. Read more.

Advice for travellers

Lassa fever is an acute viral illness that occurs in West Africa, notably in Nigeria, Guinea, and Liberia. As many as 300,000 cases and 5000 deaths occur each year. However, Lassa is a remote risk for travellers. Rodents shed the virus in urine and droppings and it is spread between humans through direct contact with the blood, urine, faeces, or other bodily secretions of an infected person.
