The mosquito (mosquito) is an ancient creature (Figure 1) that has existed since the time of the dinosaurs.
The mosquito family is huge, with more than 3,000 species.
There are footprints on all continents of the earth.
Mosquitoes can be found even in the extremely cold Arctic and Antarctic regions.
Mosquitoes can carry or transmit hundreds of pathogens and are the number one killer of humans.
According to the World Health Organization (WHO), about 1 million people worldwide are infected and killed by mosquito bites each year.
In fact, not only humans, but most other mammals on land are also affected by mosquitoes.
Figure 1 Mosquitoes after a blood meal (Photo: Zhao Lu) There are two types of viruses carried by mosquitoes: mosquito-borne viruses and mosquito-specific viruses.
Mosquito-borne viruses, such as dengue virus, Japanese encephalitis virus, Zika virus, duck tambusu virus, and eastern and western equine encephalitis viruses, can be transmitted to humans or animals and cause diseases through mosquito bites.
Common symptoms include fever, Encephalitis, arthritis and hemorrhagic fever, etc.
Mosquito-specific viruses, such as Culex flavivirus and mosquito densovirus, they only infect mosquitoes and have the potential to kill mosquitoes or block the transmission of viruses by mosquitoes.
After the founding of New China, my country attached great importance to mosquito vector control and the public health problems caused by viruses, and carried out a series of related investigations and studies.
However, there is currently a lack of a collection of vector mosquitoes and related viruses in various regions of our country, abundance, and time and space.
Information map.
Recently, researchers from the Wuhan Institute of Virology, Chinese Academy of Sciences investigated all Chinese and English documents related to "mosquitoes" and "viruses" published from 1953 to 2019 in China, and extracted information such as mosquito species, virus types, distribution, and time, and created The first known comprehensive geographic information dataset of vector mosquitoes and viruses in my country.
Studies have shown that there are 7 genera and 55 species of mosquitoes known to be vector-borne or virus-carrying mosquitoes in 31 provinces and cities in my country (Figure 2); among them, mosquito-borne viruses have 7 families, 8 genera and 26 species, and mosquito-specific viruses have 13 families and 13 families.
There are 30 species (Figure 3).
Figure 2 Types and geographical distribution of vector mosquitoes in China Figure 3 Types and geographical distribution of virus carried by vector mosquitoes in China The top five viruses most commonly found in mosquitoes in my country are Japanese encephalitis virus, Liaoning virus, dengue virus, Culex flavivirus and Banna virus; The mosquitoes that carry the most viruses are Culex tritaeniorhynchus, Aedes albopictus (Asian tiger pattern) and Culex pipiens fatigue; the distribution of mosquitoes and viruses is the highest in Yunnan Province.
Except for the plateau sub-frigid zone and cold-temperate zone, the distribution of mosquito-borne viruses or mosquito-specific viruses has been reported in other climate regions of my country.
It is worth noting that with global warming, the continuous expansion of the boundaries of mosquito distribution, and the emergence of mosquito drug resistance, the possibility of new and recurring mosquito-borne diseases is increasing.
Therefore, it is necessary to further strengthen the prevention of vector mosquitoes and mosquitoes.
Virus investigation and monitoring can better respond to its threats.
This research is the first to systematically and comprehensively reveal the types and spatial and temporal geographic distribution of vector mosquitoes and viruses in my country.
It not only has important reference value for scientists engaged in research on mosquito-borne viruses and their vectors in my country, but also serves as an important reference for Chinese mosquito-borne diseases.
Prevention and control strategies provide scientific basis and are of great significance.
Related research results were published in Scientific Data, a journal under the internationally renowned academic publishing group Nature, entitled A dataset of distribution and diversity of mosquito-associated viruses and their mosquito vectors in China And geographic distribution information comprehensive data set).
Doctoral students Evans Atoni and Zhao Lu of Wuhan Institute of Virology are the first authors of the paper.
Researcher Yuan Zhiming and associate researcher Xia Han are the co-corresponding authors of the paper.
This research was funded by the China-Africa Center Project of the Chinese Academy of Sciences (SAJC201605) and the Youth Scientific Research Project of Hubei Provincial Health Commission (WJ2019Q060).
