Explore how the {EpiLPS} R package can be used to estimate incubation times for various diseases. Learn about its applications, methodology, and benefits in epidemiological studies for more accurate predictions and better public health planning.
A group of researchers from the Data Science Institute (DSI) at Hasselt University developed a new statistical model to estimate the incubation period of a pathogenic organism based on coarse data. The incubation period of an infectious disease (defined as the time elapsed between infection and the manifestation of first symptoms) is of great importance as it permits to shed light on the epidemic potential of a disease and to optimize the length of quarantine periods to freeze transmission. The article (Gressani et al. 2024) was recently published in the American Journal of Epidemiology with practical implementation of the methodology accessible through the EpiLPS package (Gressani et al. 2022).
What makes estimation of incubation times so challenging in the first place? The devil lies in the data. True infection times are stealthy and rarely observed. In information-theoretic jargon this phenomenon is called “imperfect information’’ but statisticians prefer to call it censoring. To be more precise, infection times are…
