Brief Summary:
The project aims to use epidemiological tools to understand the transmission and evolution of influenza viruses at an individual and population level within a small-scale city (Basel) through a combination of experimental, clinical, and mathematical advances. Investigators aim to quantitatively characterize the viral transmission using novel molecular-epidemiological tools based on whole genome sequencing.
Detailed Description:
Samples will be collected such as whole blood, serum and DNA, nasopharyngeal swamps to diagnose influenza by polymerase chain reaction (PCR) and to determine colonization rates with Staphylococcus aureus and Streptococcus pneumonia. All samples except the first naso-pharyngeal swab for influenza diagnostics will be stored in a biobank and analysed in batches. Each influenza virus isolate will be sequenced using a "whole genome sequencing" approach. The viral transmission and evolution will be analysed using whole genome data for a detailed molecular and phylogenetic tree analysis, respectively. The epidemiological and geographical data will be incorporated into the phylogenetic model.
