Seroepidemiology

Seroepidemiology is the study of how diseases spread within populations by analyzing blood samples to detect specific antibodies. These antibodies are proteins the immune system produces in response to infection or vaccination. By measuring their presence and levels, researchers can estimate how many people have been exposed to a disease, understand patterns of infection, and evaluate immunity levels in the community. This information helps public health officials make informed decisions about disease control, vaccination strategies, and monitoring outbreaks, ultimately improving efforts to protect public health.
