Optimization of the control strategy and research priorities to combat the resurgence of visceral leishmaniasis in China
Leishmaniasis is a zoonotic parasitic disease caused by Leishmania infection and transmitted by sandflies.There are three main forms of leishmaniasis,including cutaneous leishmaniasis,visceral leishmaniasis and mucocutaneous leishmania-sis.China is mainly endemic for visceral leishmaniasis,which is a class C notifiable infectious disease in the country.Following concerted efforts,the transmission of visceral leishmaniasis had been controlled in most endemic foci of China by the end of 1958,with a few cases reported in western China.Due to global climate changes and population mobility,resurgence of visceral leishmaniasis has recently occurred in historical endemic areas of central and western China,which is characterized by gradual expansion of endemic areas and remarkable rebounding epidemics.Hereby,we summarize the national and global epidemiology and control strategy of visceral leishmaniasis,propose 8 key research areas and 12 key research topics for visceral leishmaniasis control,and recommend the establishment of the joint prevention and control mechanism of"human-animals-vectors"and the working mechanism of animal prevention for human diseases based on the One Health approach,so as to combat the resurgence of visceral leishmaniasis in China.
