Qalyub orthonairovirus

Qalyub orthonairovirus, also known as Qalyub nairovirus or simply Qalyub virus, is a negative-sense single-stranded RNA virus discovered in a rat's nest in a tomb wall in the Egyptian town of Qalyub (قليوب ) in 1952. The primary vector for transmission is the Carios erraticus tick, and thus it is an arbovirus.

There is no evidence of clinical disease in humans.
