Prevention and control of mosquitoes and mosquito-borne infectious diseases
Abstract:
The imported dengue cases has increased recently, and 162 autochthonous dengue cases were reported in 2014 in Japan. Since late 2014, the Zika virus has spread widely throughout the Americas. The surveillance for the invasion of these mosquito-borne infectious diseases is indispensable. Japanese encephalitis is found throughout Asia and there is still a risk of human infection in Japan. Over 3,500 species of mosquitoes have been documented through- out the world, and over 100 in Japan. Among these, we suggest the following four are the major vector mosquitoes in Japan: Culex pipiens, Culex tritaeniorhynchus, Aedes albopictus, and Anopheles spp. Here, I introduce the characteristics of each vector mosquito species, with an aim to aid the prevention and control of mosquito-borne infectious diseases.
Insights
Increased imported dengue cases in Japan highlight the need for surveillance of mosquito-borne diseases. This study details key vector mosquitoes, including Culex pipiens and Aedes albopictus, to aid prevention efforts.
Area of Science:
- Medical Entomology
- Infectious Disease Epidemiology
Background:
- Rising imported dengue cases in Japan and global Zika virus spread necessitate enhanced surveillance.
- Japanese encephalitis poses a continued human infection risk in Japan.
- Over 100 mosquito species exist in Japan, with several identified as significant vectors.
Purpose of the Study:
- To identify and characterize major mosquito vectors in Japan.
- To support the prevention and control of mosquito-borne infectious diseases.
Main Methods:
- Review of documented mosquito species in Japan.
- Identification of key vector species based on disease transmission potential.
Main Results:
- Four major vector mosquitoes identified in Japan: Culex pipiens, Culex tritaeniorhynchus, Aedes albopictus, and Anopheles spp.
- Detailed characteristics of each vector species are introduced.
Conclusions:
- Understanding vector mosquito characteristics is crucial for effective disease prevention and control strategies in Japan.
- Surveillance and management of these vectors are essential to mitigate risks from diseases like dengue, Zika, and Japanese encephalitis.
