Herein, we report a 1-year follow-up study in which we were able to collect a second blood samples from 88.7% of participants of the same cohort. We identified 23 seroconversions for IgG antibodies reactive against Lassa virus, representing an incidence of 6.3% (95% confidence interval = 3.8\u20138.8%). Seroconversion was frequently seen in preteenage children (12\/23, 51.7%) and two household\/familial clusters were identified. These results confirm active transmission of Lassa virus is occurring in southern Mali and appropriate diagnostic testing should be established for this etiological agent of severe viral hemorrhagic fever.<\/jats:p>","DOI":"10.4269\/ajtmh.16-0821","type":"journal-article","created":{"date-parts":[[2017,1,17]],"date-time":"2017-01-17T01:50:41Z","timestamp":1484617841000},"page":"944-946","source":"Crossref","is-referenced-by-count":19,"title":["Annual Incidence of Lassa Virus Infection in Southern Mali"],"prefix":"10.4269","volume":"96","author":[{"given":"David","family":"Safronetz","sequence":"first","affiliation":[{"name":"Zoonotic Diseases and Special Pathogens, Public Health Agency of Canada, Winnipeg, Canada."},{"name":"University of Manitoba, Winnipeg, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nafomon","family":"Sogoba","sequence":"additional","affiliation":[{"name":"University of Sciences, Techniques and Technologies of Bamako, Bamako, Mali."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sory Ibrahim","family":"Diawara","sequence":"additional","affiliation":[{"name":"University of Sciences, Techniques and Technologies of Bamako, Bamako, Mali."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sidy","family":"Bane","sequence":"additional","affiliation":[{"name":"University of Sciences, Techniques and Technologies of Bamako, Bamako, Mali."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyle","family":"Rosenke","sequence":"additional","affiliation":[{"name":"Laboratory of Virology, Rocky Mountain Laboratories, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Hamilton, Montana."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ousmane","family":"Maiga","sequence":"additional","affiliation":[{"name":"University of Sciences, Techniques and Technologies of Bamako, Bamako, Mali."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matt","family":"Boisen","sequence":"additional","affiliation":[{"name":"Zalgen Labs, LLC, Germantown, Maryland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert F.","family":"Garry","sequence":"additional","affiliation":[{"name":"Tulane School of Medicine, New Orleans, Louisiana."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis M.","family":"Branco","sequence":"additional","affiliation":[{"name":"Zalgen Labs, LLC, Germantown, Maryland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.
