It is endemic in Africa, southern Europe, Middle East, Central Asia, West Asia and Oceania. The main clinical manifestations are fever, rash and lymphadenopathy, invasion of the central nervous system, and encephalitis.

The incubation period of the disease is 1-6 days, some of which are as long as 20 days. The clinical manifestations were fever and encephalitis.

High fever can cause facial flushing and conjunctival congestion. Axillary and inguinal lymph node enlargement, no obvious tenderness. About half of the patients developed rashes during the fever period or at the end of the fever period.
