Dengue and Zika virus infection patterns vary among Aedes aegypti field populations from Belo Horizonte, a Brazilian endemic city

Qi Shi and colleagues find that parasite culturing and qPCR detection of bone marrow samples facilitate the diagnosis of visceral leishmaniasis associated hemophagocytic lymphohistiocytosis, but prompt treatment with anti-Leishmania and immunosuppressive chemotherapy can reduce mortality.

Ana C. Vicente Santos and colleagues demonstrate that the yellow fever vaccine elicits an immune response that protects against cerebral infection by zika virus. Their findings suggest the possibility of using an available and inexpensive vaccine for large-scale immunization in the event of a ZIKV outbreak. 

Hadian Iman Sasmita and colleagues conclude that the ovitrap surveillance system is a sensitive tool for monitoring the population dynamics of Aedes vectors, predicting dengue outbreaks, and potentially improving community-based conventional larval surveillance.
