Article Synopsis
- - In 2010, Niger implemented a new vaccine for meningitis, leading to a study analyzing bacterial meningitis cases from 2010 to 2018, confirming 5590 cases out of over 21,000 suspected.
- - The main bacteria found were Neisseria meningitidis (85%), Streptococcus pneumoniae (13%), and Haemophilus influenzae (2%), with no cases of NmA reported after 2011.
- - The patterns of meningitis serogroups changed over time, indicating the necessity for ongoing surveillance to adapt vaccine strategies effectively in Niger.
Objective: To inform public health recommendations, we evaluated the effectiveness and efficiency of current and hypothetical surveillance and vaccine response strategies against Neisseria meningitidis C meningitis epidemics in 2015 in Niger.
Methods: We analysed reports of suspected and confirmed cases of meningitis from the region of Dosso during 2014 and 2015. Based on a definition of epidemic signals, the effectiveness and efficiency of surveillance and vaccine response strategies were evaluated by calculating the number of potentially vaccine-preventable cases and number of vaccine doses needed per epidemic signal.
Background: Globally, pneumonia is the leading cause of morbidity and mortality in children, with the highest burden experienced in sub-Saharan Africa and Asia. However, there is a dearth of information on the etiology of severe acute respiratory illness (SARI) in Africa, including Niger.
Methods: We implemented a retrospective study as part of national influenza sentinel surveillance in Niger.
Article Synopsis
- A study conducted in Niger from April 2009 to April 2013 aimed to document the epidemiology of influenza among patients with influenza-like-illness (ILI) and severe acute respiratory illness (SARI).
- Of the 2,128 cases tested, 200 were positive for influenza virus, with the highest positivity rates found in the 5-14 and 1-4 year age groups, and the predominant strains identified were A(H1N1)pdm09, A(H3N2), and B.
- The research highlighted the importance of continuous surveillance to understand seasonal influenza patterns and monitor potentially pandemic strains in the region.
Emergence of Schistosoma mansoni in the Niger River valley, Niger.
Trans R Soc Trop Med Hyg
May 2004
Urinary and intestinal schistosomiasis are both endemic in Niger with a dominance of Schistosoma haematobium. This study pointed out the appearance of the infection to S. mansoni in the Niger River valley, where it was until then unknown in Niger.
