During the American epidemic, Zika virus (ZIKV) expanded rapidly through dengue (DENV)-endemic regions. We analyzed presentation of ZIKV infection in patients from City Orán, Argentina, and compared some its features with same region.A retrospective study was conducted at San Vicente de Paul Hospital during 2016-2018. Clinical demographic characteristics, pre-existing immunity to DENV, viral load type I interferon (IFN) responses were studied 63 infection.Clinical manifestations generally...
Abstract Background Serum levels of IgG antibodies against SARS-CoV-2 spike protein (S) in children who suffered COVID-19 have been found to last between 4 12 months. We aimed characterize the antibody response after 1 year unvaccinated and vaccinated children. Methods A cohort study included (< 18 years) with a previous infection. Blood samples were collected during acute phase, convalescence suffering disease. For comparative purposes, adult relatives same period included. S serum...
Abstract Background Specific humoral response against pre-fusion (pre-F) conformation of respiratory syncytial virus (RSV) F protein has been proposed to play a role severe infection. We aimed analyze the association between serum IgG titers pre-F and post-fusion (post-F) conformations RSV life-threatening disease (LTD) in previously healthy infants. Methods Prospective cohort study including infants < 12 months, hospitalized with first infection, 2017-2019. Patients were defined have...
