Serological Survey

A serological survey is a study that tests blood samples from a group of people to check for signs of past or current infection, such as antibodies. This helps researchers understand how widespread a disease is within a community, identify who has been exposed, and estimate the level of immunity. These surveys are valuable for tracking disease outbreaks, making informed public health decisions, and assessing the effectiveness of vaccines or other interventions. By analyzing blood, scientists can gather important information about disease prevalence without needing to diagnose active cases.
