The epidemiology of rubella in Mexico: seasonality, stochasticity and regional variation.

Seasonality and time patterns in attempted suicide in Ilam province of Iran: An appraisal of current data of 2010 -2014

Background: Seasonality in suicide has been investigated from the early 19th century to explore the productive environmental variables. Seasonality studies can provide information on prevention and interventions in suicide. In this study, we examined seasonality in suicide and aimed to explore the differences in seasonality between rural and urban areas, mental disorders, and genders. Method...

Associations of Suicide Seasonality with Rural- Urban Residence and Mental Disorders in Ilam, Iran

Scaling of Stochasticity in Dengue Hemorrhagic Fever Epidemics

In this paper we analyze the stochastic version of a minimalistic multi-strain model, which captures essential differences between primary and secondary infections in dengue fever epidemiology, and investigate the interplay between stochasticity, seasonality and import. The introduction of stochasticity is needed to explain the fluctuations observed in some of the available data sets, revealing...

Sequence and Phylogenetic Analysis of Wild Type Rubella virus isolated in Iran

Background and Aims: Rubella virus is a human pathogen that causes congenital rubella syndrome (CRS) when infection occurs during early pregnancy. Vaccination programs have been remarkably successful in controlling natural rubella infection and CRS. Moreover, ongoing surveillance for all cases of rubella and CRS is a vital component of a prevention program. Although the WHO recommends the use o...

Seasonally forced disease dynamics explored as switching between attractors

Biological phenomena offer a rich diversity of problems that can be understood using mathematical techniques. Three key features common to many biological systems are temporal forcing, stochasticity and nonlinearity. Here, using simple disease models compared to data, we examine how these three factors interact to produce a range of complicated dynamics. The study of disease dynamics has been a...
