RESUMO
The connection between nephropathia epidemica (NE) and vegetation dynamics has been emphasized in recent studies. Changing climate has been suggested as a triggering factor of recently observed epidemiologic peaks in reported NE cases. We have investigated whether there is a connection between the NE occurrence pattern in Belgium and specific trends in remotely sensed phenology parameters of broad-leaved forests. The analysis of time series of the MODIS Enhanced Vegetation Index revealed that changes in forest phenology, considered in literature as an effect of climate change, may affect the mechanics of NE transmission.

Fifty years after the last report of Mycobacterium ulcerans infections (Buruli ulcer [BU]) in Kasongo Territory, Maniema Province, Democratic Republic of Congo (DRC), we conducted a small-scale cross-sectional survey to assess if this historical BU focus was still active and if so to explore the disease epidemiology. Seventy-five active and inactive BU cases were identified on clinical grounds of which two of 28 BU active cases were laboratory confirmed. We used a modified BU02 form to reconstruct the local disease dynamics and we believe that the horrific conflict in eastern DRC and exceptional flooding were the most likely causes of the re-emergence of the disease. There is a need in the DRC to decentralize and integrate surveillance and control activities at local level to increase the effectiveness of patient management.
