[Serological evidence of Lassa virus circulation in the Republic of Guinea]

Seroepidemiological investigations in Guinea were carried out to estimate the areas of Lassa virus circulation. The recombinant protein of Lassa virus nucleocapsid was used as the antigen to analyse blood sera by ELISA. In some regions, from 30 to 54.9% of the population had antibodies to Lassa virus, but in others only 6-7%.
