Individual guts were placed into a drop of saline and examined microscopically for the localisation and intensity of Leishmania infections. The relationship between dengue and Zika cross-reactive antibody interactions may be complex: high dengue antibody titers might provide some protection against Zika infection, while low titers might favor enhancement.
This study provides experimental evidence that L. Lutzomyialongipalpis and the eco-epidemiology of American visceral leishmaniasis, with particular reference to Brazil: a review.

For component 2, the scores of recent and past ZIKV infection were higher among mothers of cases mean rank: Skip to main content Skip to sections. Considering the relatively low frequency of markers of recent ZIKV exposure at delivery, screening for ZIKV immune status should be performed in the early stage and throughout pregnancy to monitor congenital ZIKV syndrome in endemic areas.

Laboratory confirmation of ZIKV infection during pregnancy is challenging due to cross-reactivity with other flaviviruses, especially dengue. Acta Trop. Nevertheless, both studies showed that at delivery markers of recent ZIKV infection among mothers might not be detectable. DENV-4 predominantly circulated in the setting after its introduction in The main concern regarding serological assays is the potential for cross-reactivity of antibodies induced by DENV and ZIKV, posing a challenge in accurately differentiating infection by these viruses [ 11 — 1820 ].
