The World Health Organization (WHO) has published updates on Lassa fever transmission in Liberia and Nigeria.

In Liberia, 14 cases were confirmed between 8 February and 3 March 2019. The cases were in Bong (six), Nimba (five), Grand Bassa (one), Grand Kru (one) and Montserrado (one) counties. The WHO reported a total of 36 cases including four deaths since the beginning of 2019.

In Nigeria, in the week ending 17 March 2019, 23 cases (including four deaths) were reported from nine states, with Edo (eight) and Ondo (four) states having reported 52% of the total cases. In 2019, 73 local government areas across 21 states have reported at least one confirmed case.

Lassa fever is low risk to most travellers to Liberia and Nigeria, unless living in poor sanitary conditions in rural overcrowded areas. Health care workers in these regions are at risk if appropriate infection control measures are not followed. Travellers, who develop symptoms after returning from affected areas, should seek immediate medical advice.

Further information and advice is available on the TRAVAX (for health professionals) and fitfortravel (for the general public) websites.
