Growth and Survival of a Cohort of Congenital Zika Virus Syndrome Children Born With Microcephaly and Children Who Developed With Microcephaly After Birth.

Background And Objectives: Little is known about the clinical course of children born with congenital Zika virus syndrome (CZS). This article aimed to analyze the growth and survival of children with CZS born with microcephaly and children who developed with microcephaly after birth in the 36-month period.

Methods: This is a cohort of children diagnosed with CZS who were monitored in a series of outpatient appointments, with clinical and demographic information and anthropometric measurements collected.

Long-term chronic infection of a young immunocompromised patient by the SARS-CoV-2 P.2 VOI.

An immunocompromised patient was infected by the SARS-CoV-2 variant of interest named Zeta (P.2) in February 2021. More than one year later, he suffered from symptomatic COVID-19 and sequencing revealed the same variant, which accumulated 23 substitutions.

Measles seroprevalence in adolescents and young adults living with HIV and response to MMR booster in seronegative ones.

Objective: The study analyzed people with HIV (PWH) measles seroprevalence and response to MMR booster given to seronegative individuals.

Design: A prospective cohort study with four groups: vertically (v-HIV), horizontally infected (h-HIV) individuals, and two control groups. An MMR booster was offered to seronegative individuals.

Pertussis antibodies and vaccination coverage among healthcare professionals in Brazil is inadequate: A cross-sectional serological study.

Introduction: Worldwide, tetanus-diphtheria-acellular pertussis (Tdap) vaccination coverage of healthcare professionals (HCPs) is below 40%, but this data is not available for Brazil. We hypothesize that a high number of HCPs are not immune to pertussis in Brazil. Main objective was to determine the seroprevalence of anti-pertussis toxin (anti-PT IgG) among HCPs.
