I use Susceptible-Infected-Recovered (SIR) models to track polio infections through populations. In the pre-vaccine era, polio infections typically occurred in infants and children, with individuals over 6 months old being susceptible to paralytic and non-paralytic polio. https://memartinez.org/wp-content/uploads/2013/09/imperial_seminar.jpgImperial_seminarhttps://memartinez.org/wp-content/uploads/2013/09/polio_sketch.jpgpolio_sketchhttps://memartinez.org/wp-content/uploads/2013/09/polio_seminar_flyer.jpgPolio_seminar_flyer2017-06-30T01:17:24+00:00weekly0.6https://memartinez.org/birth-seasonality-childhood-infections/https://memartinez.org/wp-content/uploads/2014/04/phase_response_movie_black.gifphase_response_movie_blackThe size of measles epidemics can vary depending on the timing of the seasonal birth pulse. The x-axis covers 2 years because we were modeling measles outbreaks that are biennial (i.e., an outbreak occurs every-other-year during the same seasonal window). The solid line shows what would happen if the birth peak occurred the first week of the year. As the movie loops through, the birth peak is being changed from week 1, week 2,..., week 52. The reason the timing of the birth pulse matters is because measles is seasonally transmitted. Thus, if the birth peak happens during the high transmission season, then the influx of susceptible infants makes the epidemic bigger. The take away is that seasonal host reproduction can influence the incidence of disease.https://memartinez.org/wp-content/uploads/2014/04/phase_response_movie.gifphase_response_movieThe size of measles epidemics can vary depending on the timing of the seasonal birth pulse.
