Many initial encounters between host and pathogen—for example, the stinging bite of a malaria-infected mosquito (shown here)—cause no disease, but when infection does take hold, a complex chain of interactions between host and pathogen occurs that defines the outcome. In a series of specially commissioned articles and additional online material, host-pathogen interactions are explored (http://www.nature.com/ni/focus/pathogenesis/). Artwork by Lewis Long.
