What is Surveillance?
Surveillance means watching and checking health information. It can include many things. For example, it may track diseases, health behaviors, and health outcomes. Public health officials use this information to make decisions.
Why is Surveillance Important?
Surveillance plays a big role in public health. Here are some reasons why it is important:
- Early Detection of Diseases: Surveillance helps find diseases early.

- Health Trends: Surveillance shows health trends in communities.
- Resource Allocation: It helps decide where to send resources.
- Policy Making: Data from surveillance helps make health policies.
How Does Surveillance Work?
Surveillance works through different steps. First, data is collected. This data can come from hospitals, clinics, or labs. Then, it is analyzed. Health officials look for patterns and trends. Finally, they share this information with the public. This helps keep everyone informed.
Types of Surveillance
There are several types of surveillance. Each type serves a different purpose. Here are some common types:
1. Disease Surveillance
This type tracks specific diseases. It helps find how many people are sick. It also helps see where the disease is spreading.
2. Behavioral Surveillance
This type looks at health behaviors. It studies things like smoking, drinking, and exercise. Understanding behaviors helps in creating health programs.
3. Environmental Surveillance
This type checks environmental factors. For example, it looks at air and water quality. Poor conditions can lead to health problems.
4. Syndromic Surveillance
This type looks for symptoms rather than specific diseases. It helps find outbreaks early. For example, it may track flu-like symptoms.
