This image displays a close-up of two open pages of a book, suggesting an academic or informational context. The left page has partial text including "aches", "-1", and "t ysis", indicating it is likely a continuation from a previous page. The right page features a prominent heading: "Public Health Surveillance Approaches -2". Below this heading, two distinct types of surveillance are defined and explained. The first, "Indicator based surveillance (IBS)", is described as a systematic collection, monitoring, and interpretation of structured data. The second, "Event-based surveillance (EBS)", is defined as the organized collection, monitoring, assessment, and interpretation of mainly unstructured ad hoc information. The text highlights keywords like "structured data", "well-identified", "formal sources", and "unstructured ad hoc information". A page number "11" is visible at the bottom right. The background consists of a textured, light brown surface, possibly a table or floor, with some darker imperfections. The lighting suggests an indoor environment, possibly with natural light. There are no people or obvious interactions visible in the image. The image does not provide any specific information about the city of Jalingo, Nigeria.
