Summary of strategies that could be used to prevent the transmission of arboviruses to humans

Level of action	Ultimate goal	Strategies that could be used
Vector	Reduce the prevalence of vectors and their capacity to transmit viruses	Direct killing of vectors by spreading of insecticides [12]
		Limitation of vectors’ reproduction by [13–16]:
		Destroying breeding sites and promoting good sanitary conditions
		Releasing sterile or genetically modified vectors
		Introducing biological control agents
		Wolbachia-based methods: population replacement with transinfected vectors displaying reduced vector competence [17,18▪▪], or population suppression (Incompatible Insect Technique) [19]
Host–vector interface	Avoid bites [6]	Use of bed nets
		Use of repellents
		Sensitization of travellers and communities at risk
Human host	Reduce host susceptibility to arboviruses	Vaccine [20–23]
		Chemoprophylaxis [24]
