The multidimensional nature of dengue virus (DENV) infections, which can be caused by four distinct serotypes of the virus, complicates the sensitivity of assays designed for the diagnosis of infection.Different viral markers can be optimally detected at different stages of infection.Of particular clinical importance is the early identification of

Headwater streams contribute a significant proportion of the total flow to many river systems, especially during summer low-flow periods.However, despite their importance, the time taken for water to travel through headwater catchments and into the streams (the transit time) is poorly understood.Here, 3H activities of stream water are used to defin
