M. Santos-vega, P. P. Martinez, et al.

This study conducted by M. Santos-Vega, P. P. Martinez, K. G. Vaishnav, V. Kohli, V. Desai, M. J. Bouma, and M. Pascual reveals a significant link between relative humidity and urban malaria variability in Indian cities. With insights from years of surveillance data and advanced modeling, the research underscores the critical impact of RH on malaria spread and the challenges posed by climate change on malaria control efforts.

Abstract
This study investigates the impact of relative humidity (RH) on the interannual variability of urban malaria in Surat and Ahmedabad, India. Using process-based dynamical models and nearly two decades of surveillance data, the researchers found a significant effect of pre-transmission season humidity on malaria burden in both cities. Simulations accurately captured observed variability and prospectively predicted disease incidence. The findings highlight the critical role of RH in urban malaria spread and suggest that climate change and inadequate hydrological planning could hinder malaria elimination efforts.
