The SIR model of epidemic spreading can be reduced to a nonlinear differential equation with an exponential nonlinearity. This approximated by sequence equations polynomial nonlinearities. from the obtained are treated Simple Equations Method (SEsM). allows us obtain exact solutions some these equations. We discuss several solutions. Some (but not all) used for description evolution waves. this connection. In addition, we use two study COVID-19 waves in Bulgaria comparison available data infected individuals.

We studied obtaining exact solutions to a set of equations related the SEIR (Susceptible-Exposed-Infectious-Recovered) model epidemic spread. These may be used waves. transformed into differential equation that contained an exponential nonlinearity. This was then approximated by which polynomial nonlinearities. solved several from using Simple Equations Method (SEsM). In doing so, we obtained many new corresponding equations. Several these can describe evolution waves affect small percentage individuals in population. Such have frequently been observed COVID-19 pandemic recent years. The discussion shows SEsM is effective methodology for computing nonlinear help us understand various processes modeled systems. specific case model, some better quantities connected

The mutual influence between information and infectious diseases during the spreading process is becoming increasingly prominent. To elucidate impact of factors such as higher-order interactions, interpersonal distances, asymptomatic carriers on coupled propagation diseases, a novel model constructed based two-layer complex network, where one layer network another weighted network. interactions in are characterized using 2-simplex, sUARU (simplicial unaware-aware-removed-unaware) employed to articulate propagation. inter-individual social distances disease represented by weights an SEIS (susceptible-exposed-infected-susceptible) utilized describe dynamic equations formulated utilizing microscopic Markov chain approach. An analytical expression for epidemic threshold obtained deriving it from steady-state form equations. Comprehensive simulations conducted scrutinize characteristics model. findings indicate that enhancing effects increasing both lead higher outbreak thresholds greater diseases. Additionally, stronger infectivity among extended incubation period favorable spread epidemic. These can provide meaningful guidance prevention control real-world epidemics.

Abstract In times of a global pandemic, public transit can be crucial to spreading viruses, especially in big cities. Many works have shown that the human infection risk could extremely high due length exposure time, transmission routes, and structural characteristics during transportation, this result rapid spread infection. Vaccines are often part strategies reduce contagion; however, they scarce pandemic settings. Considering real-world large-scale traffic data, work proposes using time-varying multilayer networks identify main critical places prioritized interventions, such as vaccination campaigns, help contagion on transit. We exemplify our strategy different scenarios. First, when considering only bus stops priority points, determined by approach, we indicate focusing these locations reduces fewer doses than random vaccination. another experiment, demonstrate flexibility approach identifying other points interest, healthcare units case. Vaccination vital health also viable curb predetermined number doses. The proposed study is not limited strategies. It applies problems share similar properties, even several contexts, optimization or exploring interest gather insights from issues interest.
