Rapid diagnostic tests (RDTs) and advanced vaccine technologies are pivotal in the control and management of infectious diseases. These innovations enable quicker detection, timely treatment, and effective containment of outbreaks. RDTs are essential for early case identification and surveillance, particularly in low-resource settings, while new vaccine technologies, such as mRNA vaccines, have revolutionized vaccine development and distribution, offering rapid, cost-effective, and adaptable solutions to emerging viral threats.
