  1. 1Infection rate (IR) is the proportion of DENV-infected mosquitos (incidence of virus in the body) of the total mosquito sample (n = 40). 2The vector competence (VC) is the proportion of DENV-infected mosquito heads (assuming the presence of virus in the salivary gland) of the total mosquito sample (n = 40). 3The disseminated infection rate (DIR) is the proportion of DENV-infected mosquito heads (VC) of an infected population with virus in the body (IR).
