viral respiratory pathogens in Kenya; multi-site sentinel surveillance study # viral-respiratory-pathogens-in-Kenya-multi-site-sentinel-surveillance-study viral respiratory pathogens in Kenya; multi-site sentinel surveillance study Vira respiratory infections constitute a major global health challenge, causing significant morbidity and mortality worldwide, particularly in developing regions (World Health Organization [WHO], 2022). These infections result in an estimated 3-5 million cases of severe illness annually on a global scale, highlighting the magnitude of this health burden. The landscape of respiratory pathogens is diverse and complex, encompassing various viruses including influenza A and B, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), rhinoviruses, and coronaviruses, including SARS-CoV-2 (Smith & Johnson, 2021). In tropical regions like Kenya, the transmission dynamics of respiratory viruses differ from temperate zones, exhibiting less pronounced seasonality and potential year-round circulation. The landscape of viral respiratory pathogens is complex and dynamic, encompassing a wide range of viruses including influenza A and B, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), rhinoviruses, and coronaviruses, including the recently emerged SARS-CoV-2. The relative prevalence and impact of these pathogens vary significantly based on geographical location, seasonal patterns, and host factors. In tropical regions like Kenya, the transmission dynamics differ from temperate zones, with less pronounced seasonality and potential year-round circulation of viruses. Respiratory tract infections remain a significant public health concern in Kenya, particularly affecting vulnerable populations such as children, the elderly, and immunocompromised individuals (Ministry of Health Kenya, 2023). Between 2018 and 2019, influenza-like illness (ILI) and severe acute respiratory infections (SARI) accounted for 10% of outpatient consultations in Kenyan healthcare facilities (Kenya National Bureau of Statistics [KNBS], …
