The objective of this communication is to explain and demonstrate the process of epidemiological transition, using Mexico's experience as an example. The concept of 'epidemiological transition' has been in use for at least 25 years; the phrase, coined by Abdel Omran in 1971, refers to a ...
For example, individuals could be sampled as they transition from the exposed to the infected class, or while they are in the infected class. We chose to sample upon recovery based on symptom development (and thereby testing) often occurring following peak viral load. Implementation of the ...
The functional dependence of the basic reproductive number R0 on the model’s defining parameters reveals the role of spatial fluctuations and leads to a novel expression for R0. Special attention is given to simulations of inter-regional transmission of the contagion. The scaling of the epidemic ...
Table 1. Transitions between classes in the stochastic SEICWH model. The notation A→ B means that when the event occurs one individual is transferred from compartment A to compartment B. EventTransitionRate at which event occurs (re)Infection S→ E1 βs(i1 + i2)/Ω W→ E1 βw(i1+i...
where neural networks were employed to approximate transition rates among individuals in different compartments246. Other studies used neural networks to approximate decision variables, thereby transforming the optimal control problem into a parameter learning problem. Identifying the optimal control strategy pa...
The coordination and integration of prevention and intervention services across multiple levels of influence can provide the support to youth and their families that is needed to delay the onset of alcohol use and to reduce alcohol-related harm during the transition to young adulthood.

An example output of this model, fitting the Swedish data, is briefly described here:https://twitter.com/houterkabouter/status/1256123165346062336 Age-structured model This model is implemented as 'R/models/model-age.R' This is the model that has been described in the paper linked above. It ...
In the ε-SIS model, an additional infection rate ε is introduced to describe possible infection through contacts with the external, off-the-network, environment. Hence, the infection rate is px(i→nf)y = In(x)β + ε. Exam- ples of the Markov transition graph are shown in Fig. ...
