  1. 1. The Final Size of Multitype Chain-Binomial Epidemic Processes

    Författare :Mikael Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multitype epidemic process; counting process; Markov process; weak convergence; counting process;

    Sammanfattning : A multitype chain-binomial epidemic process is defined for a closed finite population by sampling a simple multidimensional counting process at certain points. The final size of the epidemic is then characterised, given the counting process, as the smallest root of a non-linear system of equations. LÄS MER

    Sammanfattning : This dissertation investigates the public response to HIV/AIDS in Sweden in the 1980s and early 1990s. The analysis focuses on the National Commission on AIDS (NCA,“Aidsdelegationen”). LÄS MER

  4. 3. Stochastic epidemics on random networks

    Författare :Abid Ali Lashari; Pieter Trapman; Filip Lindskog; Peter Neal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Branching process; Configuration model; Random graph; Epidemic process; Final size; Threshold behaviour; Duration of an epidemic; Vaccination; Mathematical Statistics; matematisk statistik;

    Sammanfattning : This thesis considers stochastic epidemic models for the spread of epidemics in structured populations. The asymptotic behaviour of the models is analysed by using branching process approximations. The thesis contains four manuscripts. LÄS MER

  5. 4. Stochastic Epidemic Models : Different Aspects of Heterogeneity

    Författare :Mathias Lindholm; Tom Britton; Maria Deijfen; Gianpaolo Scalia Tomba; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis is concerned with the study of stochastic epidemic models for infectious diseases in heterogeneous populations. All diseases treated are of SIR type, i.e. individuals are either Susceptible, Infectious or Recovered (and immune). LÄS MER
