Situation report: Location: Banjul, The Gambia. Pathogen: novel respiratory disease. Background: index case travelled to London in Dec 2022. 85 symptomatic individuals identified in February 2023 are under investigation. Modified data: linelist: added travel history column, added imported case column, added id column, added missing cases, introduced errors; contact database: added missing cases and introduced errors. Questions: 1. What are the most affected groups? 2. What are the epidemiological characteristics of infection? 2. What is the level of individual variation of transmission? 3. How is the outbreak likely to develop over the next weeks? 4. What public health measures are required to contain it?
