We analyze the role of disease containment policy in form treatment a stochastic economic-epidemiological framework which probability occurrence random shocks is state-dependent, namely it related to level prevalence. Random are associated with diffusion new strain affects both number infectives and growth rate infection, such realization may be either increasing or decreasing infectives. determine optimal steady state framework, characterized by an invariant measure supported on strictly positive prevalence levels, suggesting that complete eradication never possible long run outcome where instead endemicity will prevail. Our results show that: (i) independently features state-dependent probabilities, allows shift leftward support measure; (ii) probabilities affect shape spread distribution over its support, allowing for alternatively highly concentrated low levels more out larger range (possibly higher) levels.

Infectious diseases place a heavy burden on public health worldwide. In this paper, we systematically investigate how machine learning (ML) can play an essential role in quantitatively characterizing disease transmission patterns and accurately predicting infectious risks. First, introduce the background motivation for using ML risk prediction. Next, describe development application of various models prediction, categorizing them according to models’ alignment with vital concerns specific two distinct phases propagation: (1) pandemic epidemic (the P-E phaseS) (2) endemic elimination E-E phaseS), each presenting its own set critical questions. Subsequently, discuss challenges encountered when dealing model inputs, designing task-oriented objectives, conducting performance evaluations. We conclude discussion open questions future directions.

Due to the non-linear and non-stationary nature of daily new 2019 coronavirus disease (COVID-19) case time series, existing prediction methods struggle accurately forecast number cases. To address this problem, a hybrid framework is proposed in study, which combines ensemble empirical mode decomposition (EEMD), fuzzy entropy (FE) reconstruction, CNN-LSTM-ATT network model. This framework, named EEMD-FE-CNN-LSTM-ATT, applied predict COVID-19 study focuses on dataset from United States as research subject validate feasibility framework. The results show that EEMD-FE-CNN-LSTM-ATT outperforms other baseline models all evaluation metrics, demonstrating its efficacy handling epidemic series. Furthermore, generalizability validated datasets France Russia. offers approach for predicting pandemic, providing important technical support future infectious forecasting.

When an epidemic breaks out, many health, economic, social, and political problems arise that require a prompt effective solution. It would be useful to obtain all information about the virus, including epidemiological ones, as soon possible. In previous study of our group, analysis positive-alive was proposed estimate duration. stated every ends when number (=infected-healed-dead) glides toward zero. fact, if with contagion everyone can enter phenomenon, only by healing or dying they get out it. this work, different biomathematical model is proposed. A necessary condition for resolved mortality reaches asymptotic value, from there, remains stable. At time, must also close This seems allow us interpret entire development highlight its phases. more appropriate than one, especially spread infection so rapid increase in live positives staggering.
