We find that relative humidity systematically shifts the temperature dependence of a key malaria vector. These effects are also likely important for aquatic insects more generally, and for predicting their responses to climate change.

Strengthening arbovirus surveillance: bridging gaps for global health preparedness
Strengthening arbovirus surveillance: bridging gaps for global health preparedness
Despite significant advancements in arbovirus research, contributions remain disproportionately focused on regions with reported major outbreaks of diseases such as dengue, Zika, and chikungunya. This bias risks neglecting potentially critical properties in viral evolution, transmission dynamics, ecological drivers, and host–pathogen interactions that occur within the less-studied areas. Recent developments highlight the importance of incorporating data from underrepresented regions and from recent surveillance approaches to uncover novel insights that could enhance global preparedness and response strategies. This opinion explores frameworks for generating and integrating diverse geographical data, proposing equitable research approaches to better capture the global heterogeneities and properties of at-risk environments and populations. A geographically inclusive perspective is essential to address emerging arboviral challenges, particularly in the context of a changing environment and shifting land use patterns.

This a summary of last part o my Ph.D. We investigated how temperature can affect the outcome of dengue infection.
The study covers a 10y period in all five regions of Brasil and all sub-climates of the country
We conclude that higher temperature makes risk of hospitalizations due dengue bigger!

Does heat have a short effect on Dengue, increasing risk for severe cases?
We know meteorological factors affect dengue incidence, with lag effects on weeks/months.
Here, led by @rafalpx.bsky.social, we found also a short effect of heat for Dengue Hospitalisation
