"Given the still very limited number of textbooks covering within-host modeling, this new volume is a welcome addition. It is written in a fairly technical style. Therefore,immunologists, virologists, and other bench scientists, who might have limited training in differential equations and coding, might not find this the most accessible way of learning the topic. However, for individuals with a strong quantitative background, this publication provides a nice introduction to the subject of within-host modeling. After working through the book, readers will have gained a solid introduction to the field and should be ready to proceed to the primary research literature and, if desired, can start to contribute to this area of research themselves." --The Quarterly Review of Biology
