Abstract

Diptera spp. and Ixodidae spp. can transmit several diseases through their bite, a lot of them are vectorborne zoonoses that can affect humans who live near dogs. It is knowledge that isolation of reservoirs of vector-borne diseases helps to presser the transmission and down the prevalence on the diseases. During the epidemy of SARS-COVID-19 confinement in Spain, owners and dogs were isolated into their homes, reducing the Potential reservoirs for VBD and giving an awesome opportunity to check how this hypothesis is true for VBD. Sample of 3135 dogs were tested along 7 years with Quantitative Immunoassay (IFA, ELISA) and PCR test to detect antibodies and pathogen of main Mediterraneum VBD (Leishmania infantum, Anaplasma phagocytophilum, Dirofilaria immitis, Babesia canis and Ehrlichia canis), health check, blood test (hemogram, biochemical, proteinogram).Results were separated into 2 populations, pre-pandemic tested vs pandemic tested and compared both groups. We found that the levels of positive dog's pre-pandemic group were much higher than pandemic levels.This study shows that isolation of positive dogs far to healthy dogs and vectors help to low risk of contagious for other dogs and, most importantly, Humans. This information can help to preserve Public Health and avoid contagion.
