Change in Composition of the Anopheles Gambiae Complex and its Possible Implications for the Transmission of Malaria and Lymphatic Filariasis in North-Eastern Tanzania. [PDF]

open access: yes, 2012
A dramatic decline in the incidence of malaria due to Plasmodium falciparum infection in coastal East Africa has recently been reported to be paralleled (or even preceded) by an equally dramatic decline in malaria vector density, despite absence of ...

Chance-Constrained Control with Lexicographic Deep Reinforcement Learning [PDF]

open access: yes, 2020
This paper proposes a lexicographic Deep Reinforcement Learning (DeepRL)-based approach to chance-constrained Markov Decision Processes, in which the controller seeks to ensure that the probability of satisfying the constraint is above a given threshold.

Leishmaniasis worldwide and global estimates of its incidence. [PDF]

open access: yes, 2012
As part of a World Health Organization-led effort to update the empirical evidence base for the leishmaniases, national experts provided leishmaniasis case data for the last 5 years and information regarding treatment and control in their respective ...

Early warnings of the potential for malaria transmission in rural Africa using the hydrology, entomology and malaria transmission simulator (HYDREMATS)

open access: yesMalaria Journal, 2010
Background Early warnings of malaria transmission allow health officials to better prepare for future epidemics. Monitoring rainfall is recognized as an important part of malaria early warning systems.

Dengue transmission risk in a changing climate: Bangladesh is likely to experience a longer dengue fever season in the future

open access: yesEnvironmental Research Letters, 2021
Our changing climate is already affecting the transmission of dengue fever, the fastest growing vector-borne viral disease in the world. This issue presents a significant public health concern for some nations, such as Bangladesh, which already ...

A simulation model for the Chikungunya with vectorial capacity

open access: yesApplied Mathematical Sciences, 2015
We have formulated a simulation model with base in non-linear ordinary differential equations following the formalism stated by Sir Ronald Ross for the Malaria, using the therm of incidence, the vectorial capacity of the Aedes aegypti and the sinusoidal-like temperature effect in the probabilities of virus transmission to the susceptible people and to ...

Deforestation and Vectorial Capacity of Anopheles gambiae Giles Mosquitoes in Malaria Transmission, Kenya [PDF]

open access: yesEmerging Infectious Diseases, 2008
We investigated the effects of deforestation on microclimates and sporogonic development of Plasmodium falciparum parasites in Anopheles gambiae mosquitoes in an area of the western Kenyan highland prone to malaria epidemics. An. gambiae mosquitoes were fed with P. falciparum-infected blood through membrane feeders. Fed mosquitoes were placed in houses

Hydrological Alteration Index as an Indicator of the Calibration Complexity of Water Quantity and Quality Modeling in the Context of Global Change [PDF]

open access: yes, 2019
Modeling is a useful way to understand human and climate change impacts on the water resources of agricultural watersheds. Calibration and validation methodologies are crucial in forecasting assessments.

Zika Virus Infection Produces a Reduction on Aedes aegypti Lifespan but No Effects on Mosquito Fecundity and Oviposition Success

open access: yesFrontiers in Microbiology, 2018
A Zika virus (ZIKV) pandemic started soon after the first autochthonous cases in Latin America. Although Aedes aegypti is pointed as the primary vector in Latin America, little is known about the fitness cost due to ZIKV infection.
