Pathogen detection technologies, including PCR, genomic sequencing, and rapid tests, significantly improve public health by enabling quicker identification of disease-causing agents. Early detection allows for timely intervention, control measures, and treatment, leading to better outcomes in managing outbreaks. These technologies enhance surveillance systems, assist in tracking pathogen spread, and inform public health responses. Ultimately, they contribute to the prevention of widespread infections, safeguarding populations and supporting healthcare infrastructures.
