In Mexico there are limited testing and contact tracing of cases. We have, therefore, limited information for disease surveillance. Nevertheless, the need to have indicators of the state of the epidemic is a pressing need. We have developed some ideas to overcome these limitations that incorporate the traditional social behaviour of the Mexican people into our models. https://www.medrxiv.org/content/medrxiv/early/2021/04/20/2021.04.14.21255436.full.pdf YouTube and Slides.
