New Microbes and New Infections serves the field as a peer-reviewed, fully open-access journal publishing cutting-edge papers on all aspects of emerging microbes and infections. It covers new microbes that are evolving from existing organisms and microbes causing infection in new populations or moving to a new geographic area. The journal will also consider papers that predict or show the expansion of a microbe to a new ecological niche or an expanded geographic area due to climate change. Another aim of the journal is to publish papers on "old microbes" with a new presentation such as drug resistant malaria, antimicrobial resistant bacteria or re-emerging infections or organisms in new hosts or vectors. Recent emerging infections have strong links or origins to the animal world. NMNI aims to have a strong "one health" focus. The scope also covers manipulation of microbes in the lab and considers organisms of bioterror. New microbes and infections require new vaccines, new therapies or repurposed therapies. The remit of the journal covers antimicrobials, preventive approaches and therapies to combat novel microbes and the journal will be open to controversial commentaries on these themes. Another focus of the journal will be travel-acquired new microbes showing that travellers can be sentinels for new infections and outbreaks. Microbes travel as "baggage" within humans but also on travel conveyances such as aircraft, ships and trains and can become ?new microbes? in new terrain. Pandemic preparedness and response: New microbes frequently have pandemic potential. The remit of the journal also includes articles that are public health oriented. Such papers would consider or model the preparedness of healthcare infrastructures, governments or international organisations to detect, characterize and mitigate emerging microbial threats. NMNI publishes high quality systematic reviews, narrative reviews, cutting-edge original research and rapid analyses of emerging infections as well as editorials, short correspondence pieces and special issues that can be rapidly reviewed and published. The journal also has a "first sighting" section. In the "editorial notes" section, each NMNI issue will interview a famous infectious disease player in the column "NMNI Profile".
