Abstract
Biting midges are one of the most common hematophagous insects. They are capable of transmitting a wide range of arboviruses and have a significant impact on public health and veterinary medicine. Herein, from midge samples collected in 2013 in Yunnan, China, one sample induced a cell cytopathic effect (CPE) in BHK-21, MA104, and PK15 cell lines. Next-generation sequencing data, RACE and PCR determined the genome sequence of the sample and designated as an Oya virus (OYAV) isolate SZC50. Phylogenetic analysis of the sample revealed that it was cluster into viruses from species Orthobunyavirus catqueense. The open reading frames of S, M, and L segment of OYAV SZC50 were closest to those of OYAV SC0806. Moreover, 831 serum samples (736 pigs, 45 cattle, and 50 sheep) were gathered from 13 cities in Yunnan Province to detect neutralizing antibody of OYAV SZC50. A significant proportion of OYAV SZC50 antibody (more than 30%) was found in Yunnan pig populations, with the positive rate of OYAV SZC50 antibody in pigs from Malipo reaching 95%. To determine the pathogenicity of OYAV SZC50, we chose three animal models: specific pathogen-free Kunming mice, C57BL/6 mice lacking the interferon α/β receptor, and chicken embryos. At 5, 6, and 7 days post-infection, all adult and suckling C57BL/6 mice, and specific pathogen-free suckling Kunming mice were dead. Our finding was expanding the knowledge about the infection and pathogenic risk of the neglected virus in the Orthobunyavirus.

Abstract
Several infections have emerged in humans, domestic animals, wildlife, and plant populations, causing a severe problem for humanity. Since the discovery of the Monkeypox virus (Mpox) in 1958 in Copenhagen, Denmark, it has resurfaced several times, producing severe infections in humans and resulting in a significant fatality rate. Mpox is an Orthopoxvirus of the Poxviridae family. This family contains various medically important viruses. The natural reservoir of Mpox is unknown yet. Mpox might be carried by African rodents and nonhuman primates (such as monkeys). The role of monkeys has been confirmed by its various outbreaks. The infection may be transferred from unidentified wild animals to monkeys, who can then spread it to humans by crossing species barriers. In close contact, human-to-human transmission is also possible. Mpox outbreaks have been documented regularly in Central and Western Africa, but recently in 2022, it has spread to over one hundred-six countries. There is no specific treatment for it, although the smallpox vaccine, antivirals, and vaccinia immune globulin help in the effective management of Mpox. In conclusion: Monkeypox poses a severe threat to public health due to the lack of specific vaccinations and effective antivirals. Surveillance studies in affected regions can assist in the early diagnosis of disease and help to control significant outbreaks. The present review provides information on epidemiology, clinical symptoms, risk factors, diagnosis, and preventive measures of Mpox.
