Fiseha Wadilo, a PhD student at Addis Ababa University, department of Microbial Cellular and Molecular Microbiology (MCMB) and currently working on a PhD project entitled “Viral and bacterial etiologies and biomarkers of severe acute respiratory infection among under 5 years of children in selected hospitals of Ethiopia”. In Ethiopia, insight into the etiology of SARIs is very limited and much of what is known about respiratory pathogens is from data gathered in industrialized countries of the world. Therefore, thepresent study will give comprehensive SARI etiology among children using sensitive molecular diagnostic methods. Furthermore, this study will suggest the utility of some biomarkers to address the need for better diagnostics approaches that can aid in distinguishing between bacterial and viral respiratory tract infections.
