Predictive model for Zika virus RNA minipool nucleic acid testing in outbreak scenarios.

08:00 EDT 2nd April 2019 | BioPortfolio

Summary of "Predictive model for Zika virus RNA minipool nucleic acid testing in outbreak scenarios."

Zika virus (ZIKV), a mosquito-borne flavivirus, causes asymptomatic infections in blood donors and can be transmitted by transfusion. During the 2016 US outbreak, universal individual-donation nucleic acid testing (ID-NAT) was used to screen the blood supply for ZIKV. Testing pooled samples from multiple donations with minipool (MP)-NAT is less sensitive than ID-NAT, which raised questions about its utility in ZIKV outbreaks.

Medical and Biotech [MESH] Definitions

An arbovirus in the FLAVIVIRUS genus of the family FLAVIVIRIDAE. Originally isolated in the Zika Forest of UGANDA it has been introduced to Asia and the Americas.

A viral disease transmitted by the bite of AEDES mosquitoes infected with ZIKA VIRUS. Its mild DENGUE-like symptoms include fever, rash, headaches and ARTHRALGIA. The viral infection during pregnancy, however, may be associated with other neurological and autoimmune complications (e.g., GUILLAIN-BARRE SYNDROME; and MICROCEPHALY).

In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

A protein-nucleic acid complex which forms part or all of a virion. It consists of a CAPSID plus enclosed nucleic acid. Depending on the virus, the nucleocapsid may correspond to a naked core or be surrounded by a membranous envelope.

Techniques for measuring specific nucleic acid interaction with another nucleic acid or with a protein by digestion of the non-interacting nucleic acid by various nucleases. After all non-interacting regions are eliminated by nuclease digestion, the protected nucleic acid that remains is analyzed. DNA FOOTPRINTING utilizes this technique to analyze the DNA contact sites of DNA-BINDING PROTEINS.
