Abstract:
Zika virus (ZIKV) infection is an emerging public health problem, associated with increased risk for Guillain-Barré syndrome and adverse fetal outcomes, including congenital microcephaly. Zika virus sexual transmission is known, but detection of the virus in different parts of the female reproductive tract is not well established. In this case report, we describe prolonged detection of ZIKV RNA in the vaginal secretion and endocervical mucosa from a Brazilian woman convalescent to ZIKV infection. A viral load of 2 × 102 copies/mL was detected up to 31 days after symptom onset in both samples. Other biological fluids, including whole blood, plasma, serum, urine, and saliva samples, were negative for ZIKV RNA. These findings advance the understanding of ZIKV infection and provide data for additional testing strategies.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
RNA Structure
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA): messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three RNA types consist of a...
