Abstract
The target gene sequences of the novel coronaviruses obtained by sequencing were compared with the reference sequences to analyze the genetic variation of the two cases of the novel coronaviruses from Inner Mongolia Autonomous Region in 2022 and to explore the sources of infection. The results showed that the two sequences belonged to different evolutionary branches, Delta (AY.122) and Omicron (BA.1.1), respectively. hCoV-19/Inner Mongolia/IVDC-591/2022 had 48 single nucleotide polymorphisms on the genome sequences, sharing 40 nucleotide mutation sites with a Mongolian strain; hCoV-19/Inner Mongolia/IVDC-592/2022 genome shared 57 nucleotide mutation sites with a UK strain, and the nucleotide mutation site identity was 100% (57/57). Phylogenetic analysis showed that the target gene sequences were not directly related to domestic novel coronavirus sequences during the same period, but were related to isolates from Europe and Mongolia.

Abstract
Objective: To investigate the types and distribution of blood-sucking insects and arboviruses in Inner Mongolia autonomous region, and provide basic data for the prevention of arbovirus transmitted disease. Methods: Blood-sucking insects were collected by lamp trapping method in nature. Mosquito samples were classified according to morphologic characteristics and then stored at liquid nitrogen. Viruses were isolated in cell culture and characterized, using molecular biological methods. Results: A total of 24 240 mosquitoes and 17 110 aphids were collected from 2 sites of 5 counties (Flags) in Inner Mongolia in 2014 and during 2017-2018. Among them, Japanese encephalitis virus gene was detected in Culex pipiens pallens, and 4 virus strains isolates which could be stably passaged. The isolates were identified as Getah virus and densonucleosis virus by molecular biology identification. Phylogenetic analysis on the E2 gene of the Getah virus (NMDK1813-1) showed that it belonged to the same evolutionary branch of the Gansu isolates (GS10-2) and having six common amino acid variation sites. Conclusions: The emergence of Japanese encephalitis virus and Getah virus from specimen of mosquitoes in Inner Mongolia indicated the new challenges on the prevention and control of arbovirus and related diseases. The results pf this study provided basic data for the prevention and control stretagies of arbovirus transmitted diseases in Inner Mongolia.
