The spatial and temporal distributions of lumpy skin disease virus in different Egypt governorates during 2016 to 2020 followed by another descriptive study in two main risk governorates in Egypt.

Lumpy skin disease (LSD) is a viral disease that affects breeding cattle flocks in Egypt, lead to significant economic losses. This study aimed to investigate the spatial and temporal distribution of LSD from 2016 to 2020 across different affected governorates in Egypt. The surveillance data were collected from the OIE-WAHIS website followed by field investigation of LSD in two main risk governorates in Egypt. The obtained results mentioned a highly significant difference (p < 0.05) in LSD prevalence rate among Egypt governorates, with the highest prevalence rate observed in Menofia governorate at Delta. In addition to, the highest prevalence rate was recorded in 2018 with (36%), while the lowest was in 2017 with (4%). Furthermore, the temporally distribution of LSD was the highest during the period from July to December (summer and autumn) with (16.2%) of LSD prevalence rate. On the other hand, our results of descriptive study revealed that the percentages of clinically infected cattle were higher in Qalubia when compared with Menofia governorate. Finally, LSD is an endemic disease in Egypt that is present throughout the year in different governorates, with varying prevalence rates across seasons.
