Ot the patient was hospitalized.RNA extraction from clinical samplesRibonucleic acid (RNA) extraction was performed from l of each and every sample applying the QIAamp Viral RNA kit (QIAGEN, Valencia, CA, USA) as outlined by the manufacturer’s instructions.Each and every RNA sample was eluted with l nucleasefree water before RNA quantification with a Nanodrop apparatus (NanoDrop Lite, Thermo Scientific).Detection of respiratory virusesA twostep realtime RTPCR was performed applying the CFX RealTime PCR Detection ML240 Epigenetics system (BioRad).cDNA synthesis stepThe recruitment period of this potential observational study was from January to December inclusive.All sufferers aged years and above presenting with ILI throughout this period have been enrolled in the study.It must be noted that samples had been collected in the context of flu monitoring.An influenza sentinel surveillance system for outpatients with ILI was established in in Senegal and became a part of the WHO Global Influenza Surveillance and Response System (GISRS).It really is coordinated locally by the National Influenza Center (NIC) at the Institut Pasteur de Dakar.Educated health-related personnel have been asked to screen all outpatients who have been attended at the sentinel internet sites for indicators and symptoms of ILI.The symptoms of influenza are related to those arising from other viral respiratoryThe RevertAid 1st Strand cDNA Synthesis Kit (Thermo Scientific) was utilised.Initially ng of RNA was mixed with l of random hexamer primer and nuclease no cost water for a final volume of l.It was then incubated at for minutes and straight away put on ice in an effort to eliminate the secondary structures in GCrich RNA.For the cDNA synthesis step, l of X reaction buffer, l of RNase inhibitor ( ul), l of dNTP Mix ( mM) and l of RevertAid MMuLV Reverse Transcriptase ( ul) were added and incubated for minutes at followed by minutes at and for minutes.The cDNA solution may very well be utilized straight for the subsequent step (PCR amplification) or stored at until use.Dia et al.BMC Infectious Diseases , www.biomedcentral.comPage ofPCR detectionTable Demographical, viral detection and clinical dataAge groups Demographical information Mean age Gender no.
