Acute Lassa Virus Encephalitis with Lassa Virus in the Cerebrospinal Fluid but Absent in the Blood: A Case Report with a Positive Outcome

It is rare both to have the central nervous system (CNS) as the main focus in the acute phase of Lassa fever infection without associated bleeding, and to find Lassa virus (LAV) in the cerebrospinal fluid (CSF) but not in the serum. We report the case of a 38-year-old Nigerian woman with mainly CNS manifestation of Lassa fever. She was admitted twice within 11 days because of persistent fever. A clinical diagnosis of acute LAV encephalitis was made because of a high index of suspicion and CNS involvement confirmed by positive reverse transcriptase polymerase chain reaction (RT-PCR) for LAV in the CSF, while her blood was repeatedly negative for LAV by RT-PCR test. She recovered fully following supportive care coupled with treatment with an 18-day course of ribavirin, and suffered no long-term neurological complication or relapse. Post-treatment CSF examination by RT-PCR did not detect LAV

Hepatitis C virus in sub-Saharan Africa: a long road to elimination

The development of direct-acting antivirals against hepatitis C virus (HCV) has transformed the treatment landscape and underpinned the WHO goal of HCV elimination by 2030. However, as of 2021, few countries remain on track to achieve this goal. Reliable data remain scarce, especially those on national plans for HCV elimination in many regions of the world and particularly in sub-Saharan Africa, which accounts for around 11 million of 71 million people estimated to be living with HCV
