Lassa high risk areas are near the western and eastern extremes of West Africa. As of 2018, the Lassa belt includes Guinea, Nigeria, Sierra Leone and Liberia.[1] As of 2003, 10-16% of people in Sierra Leone and Liberia admitted to hospital had the virus.[2] The case fatality rate for those who are hospitalized for the disease is about 15-20%.
