Mode of transmission
LSD was recognized as a notifiable disease by the World Organization for
Animal Health (OIE) as it causes significant economic losses((AHAW),
2015). The economic losses are the outcome of restrictions of animal
products to the global trade and costly control and eradication
measures. Insect vectors (mosquitoes, flies, ticks, etc.), contaminated
needles, vehicles from the infected area play a major role in the
transmission of this virus. LSD can spread rapidly during summer and
autumn months when the environment is moist, warm favorable for the
growth and reproduction of houseflies, mosquitoes, etc. Stomoxys,
Biomyia fasciata, Tabanidae, Glossina, and Culicoides species are
considered to be the main vector for transmission(Rueda, Patel, Axtell,
& Stinner, 1990).
