What role do sentinel animals play in disease surveillance?

Sentinel animals play a crucial role in disease surveillance by acting as indicators for assessing the presence of diseases in an environment. These animals are monitored for signs of infection or disease, which can provide valuable information about the prevalence and distribution of pathogens in the area. When sentinel animals, such as birds or rodents, show signs of illness or infection, it suggests that the pathogens may be present in the local vector population or environment, allowing public health officials and vector control technicians to identify potential disease outbreaks and take appropriate preventive measures.

This approach is essential in the early detection of vector-borne diseases, which can help to implement control strategies before the diseases spread to humans or other animals. By observing the health status of sentinel species, technicians can gather relevant data that informs public health responses and targeted vector control efforts.
