Clinicians frequently ignore RSV's role in adult morbidity and mortality. RSV is associated with around 250,000 deaths annually, excluding children. Despite significant advancements in their understanding of the impact of RSV-related sickness in adults, researchers and epidemiologists still have much to learn. For instance, there is a dearth of information about RSV in underdeveloped nations. There are no research on the prevalence of RSV in any emerging nation. The implications of LRIs are typically greater in older persons in underdeveloped nations, which is problematic when creating worldwide estimates of illness burden. This gap is mostly caused by the communities' poorer socioeconomic condition, dependence on solid fuels, undernutrition, immunological dysfunction, and malnourishment. Additionally, describing the prevalence of RSV-related illness in Obtaining precise data on the incidence, hospitalisation rate, and hospital mortality rates of RSV-infected individuals in poor countries is essential. RSV infection is actually associated with worse outcomes and greater resource use than influenza illness, despite the fact that influenza has traditionally gotten more attention due to its higher incidence and the related ease of detection. Our comprehension of the significance of RSVassociated disease is likely to increase as awareness of it does.
