Disease vectors are living organisms, typically arthropods such as mosquitoes, ticks, fleas, sandflies, and triatomine bugs, that biologically or mechanically transmit pathogenic agents between hosts, thereby enabling the spread of infectious diseases within populations and ecosystems. In vector-borne disease systems, pathogens often undergo essential developmental or replication stages within the vector (biological transmission), or are passively carried on contaminated body parts (mechanical transmission). Research on disease vectors encompasses their ecology, population dynamics, host-feeding behavior, vector competence, insecticide resistance, and interactions with environmental and climatic factors, informing surveillance, risk modeling, and integrated vector management strategies for disease control.
Diseases historically absent from the United States have been showing up in Florida, Texas, California and other U.S. states in recent years. To understand why, look to Peru. That's where researchers from Stanford and other ...

Bats are reservoirs for several zoonotic viruses, such as Ebola and coronaviruses. These pathogens can spread to humans through direct contact with the flying mammals or their bodily fluids, or indirectly through contaminated ...
Two locations have been identified as the most likely entry points into Australia for a disease that poses a huge risk to the beef and dairy industries. A University of Queensland-led team has built the first geospatial model ...
