Vbd

VBD is an acronym that can refer to several different concepts, depending on the context. The most widely used meaning in public health and biology is vector-borne disease, a category of illnesses transmitted to humans or other animals by arthropod vectors such as mosquitoes, ticks, sandflies, and triatomines. These diseases arise when a pathogen—such as a parasite, virus, or bacterium—circulates between a vector and a vertebrate host.

Vector-borne diseases include a broad range of conditions, with malaria, dengue, chikungunya, Zika, Lyme disease, leishmaniasis, and sleeping sickness among the better known examples. Transmission dynamics are influenced by ecological factors, human behavior, and climate, which can affect vector distribution and activity. Public health responses typically emphasize surveillance, vector control, prevention of bites, and treatment of affected individuals. In some cases, vaccines or targeted therapies exist, though for many diseases research and control efforts remain ongoing. Global health strategies increasingly adopt a One Health perspective, recognizing the interconnectedness of human, animal, and environmental health in managing VBD risks.

In computing and information technology, VBD can also stand for virtual block device, a software abstraction that presents storage to a virtual machine as a block device. This concept underpins how virtualization platforms provide disks or disk images to guest operating systems, enabling flexible and isolated storage management within virtualized environments.
