A mathematical study to control Guinea worm disease: a case study on Chad
Journal of Biological Dynamics, 2018 Global eradication of Guinea worm disease (GWD) is in the final stage but a mysterious epidemic of the parasite in dog population makes the elimination programme challenging.

A Spatial-Temporal Model for the Evolution of the COVID-19 Pandemic in Spain Including Mobility
Mathematics, 2020 In this work, a model for the simulation of infectious disease outbreaks including mobility data is presented. The model is based on the SAIR compartmental model and includes mobility data terms that model the flow of people between different regions ...

Epidemic models and percolation
Journal of Physics A: Mathematical and General, 1985 We argue that local epidemic models with immunisation are in the same universality class as percolation cluster growth models, and show that the static exponents are equal to all orders in the \(\epsilon\) expansion. We calculate the dynamic exponent \(v_ t=1+\epsilon /28+O(\epsilon^ 2)\) and relate this to other exponents involving the chemical ...

Vaccination in a model of an epidemic [PDF]
International Journal of Mathematics and Mathematical Sciences, 2000 Vaccination has been included in a model which describes an epidemic. A traveling wave solution together with an equilibrium and stability analysis have been done to the model.

A decade of change: maternal mortality trends in Sudan, 2009–2019
BMC Public HealthBackground Unacceptably high levels of preventable maternal deaths persist across sub-Saharan Africa. Due to limited research on maternal mortality in Sudan, a thorough examination is crucial to develop effective reduction strategies.

Epidemic Models with Varying Infectivity on a Refining Spatial Grid—I—The SI Model
MathematicsWe consider a space–time SI epidemic model with infection age dependent infectivity and non-local infections constructed on a grid of the torus Td=[0,1)d, where the individuals may migrate from node to node.

Discrete-Time Household Epidemic Models [PDF]
We present a general Markovian discrete-time SIR household epidemic model based on time units of a day. The model is flexible in how within-household infection depends upon the number of infectives at a given time and the interactions between global ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Fractal and FractionalIn this study, we analyze a time-fractional spatiotemporal SIR model in a specific area Ω. Taking into account the available resources, vaccines are allocated to region ω1⊆Ω and treatments to region ω2⊆Ω, which may or may not coincide.
