In this work, we use a mathematical model for dengue transmission with the aim of analysing and comparing two epidemics that occurred in Salvador, Brazil, 1995-1996 2002. Using real data, obtain force infection, Λ, basic reproductive number, R(0), both epidemics. We also time evolution effective reproduction R(t), which results very suitable measure to compare patterns Based on analysis behaviour R(0) R(t) relation adult mosquito control parameter model, show applied only stage population is...
Even though the impact of COVID-19 in metropolitan areas has been extensively studied, geographic spread to smaller cities is also great concern. We conducted an ecological study aimed at identifying predictors early introduction, incidence rates and mortality (up 8 May 2020) among 604 municipalities inner São Paulo State, Brazil. Socio-demographic indexes, road distance state capital a classification regional relevance were included predictive models for time introduction (Cox regression),...
Public health policies to contain the spread of COVID-19 rely mainly on non-pharmacological measures. Those measures, especially social distancing, are a challenge for developing countries, such as Brazil. In São Paulo, most populous state in Brazil (45 million inhabitants), cases up April 18th were reported Capital and metropolitan area. However, inner municipalities, where 20 people live, also at risk. As governmental authorities discuss loosening measures restricting population mobility,...
Ecological modeling is an important tool for investigating dynamic behavior patterns in populations, trophic interactions, and behavioral ecology. However, the ecological that reflect population oscillation trends are often not clearly visible without analytical instruments such as models. Thus, plays a fundamental role describing demographic processes dynamics. models, besides making possible visualization of patterns, may also reveal persistence many systems, including prey-predator or...
Evidence of changing in biting and resting behaviour the main malaria vectors has been mounting up recent years as a result selective pressure by widespread long-term use insecticide-treated bed nets (ITNs), indoor residual spraying. The impact resistance on intervention efficacy important implications for epidemiology control programmes. In this context, theoretical framework is presented to understand mechanisms determining evolution feeding under ITNs. An agent-based stochastic model...
The efficacy of biological control Aedes aegypti mosquitoes using Sterile Insect Technique (SIT) is analyzed. This approach has shown to be very efficient on agricultural plagues and become an alternative strategy the usual technique insecticide application, which promotes resistance against chemical controls harmful other species that live in same mosquito habitat. By a discrete cellular automata we have case aegypti, spatially heterogeneous distribution oviposition containers behavior,...
The present study aimed to investigate how the impact of several factors linked geography would shape life-history traits in a gregarious species, using pine processionary moth (PPM) Thaumetopoea pityocampa as model system. PPM has wide geographical distribution over Mediterranean Basin, and it is strictly species throughout larval development, where total reproductive output each female forms colony. We reviewed both published unpublished data on from all its Basin extracted fecundity, egg...
In this paper, we are concerned with an epidemic model of susceptible, infected and recovered (SIR) population dynamic by considering age-structured phase protection limited duration, for instance due to vaccination or drugs temporary immunity. The is reduced a delay differential-difference system, where the duration phase. We investigate local asymptotic stability two steady states: disease-free endemic. also establish when endemic state exists, uniform persistence disease. construct...
Abstract Two hundred days after the first confirmed case of COVID-19 in Brazil, epidemic has rapidly spread metropolitan areas and advanced throughout countryside. We followed temporal pattern at São Paulo State, most populous country, to have a COVID-19, one with significant number cases until now. analysed new per day each regional health department calculated effective reproduction ( R t ) over time. Social distance measures, along improvement testing isolating positive cases, general...
The present study aimed to investigate the relationship between growth rate, final mass, and larval development, as well how this influences reproductive trade-offs, in context of a gregarious life-style need keep an optimal group size. We use model two sympatric populations pine processionary moth Thaumetopoea pityocampa, which occur different seasons thus experience climatic conditions. pityocampa is strictly caterpillar throughout period, occurs during winter countries all over...
