Fantastic to see this published! A seroprevalence study for Lassa Fever conducted by the #SierraLeonean KGH #LassaFever team and #TulaneUniversity team. Can stop using the 1970's reference now 🤣 .

Most importantly they found seroprevalence >50% from villages across the country. This overturns orthodoxy of limited distribution of #LassaFever within the country. Much more effort is required to understand this spatial heterogeneity. Which unfortunately means longer and more expensive studies.
