Modélisation de l'interaction entre les virus de la grippe et de la rougeole
People infected with measles experience immune suppression. This work focuses on the influence of this characteristic of measles on another pathogen, here the flu. We also have that the flu will increase the production of other pathogens in a co-infection model. Modeling the immune response to such virus-virus interaction is currently of signficant relevance, given the limited knowledge on SARS-CoV-2/influenza interactions. A model of each pathogen will be developed and analysed. We will look for the fixed points, conditions for their stability and we will observe some numerical results of their evolution over time. Then a model following the evolution of the two pathogens having simultaneously infected an individual will be designed. In this model we will include the interactions of the pathogens on each other to theoretically determine the effects in individuals infected with both influenza and measles. Then we can compare between the different populations when there is no interaction and with the different interactions between the two pathogens.
