- Zika virus infection is linked to brain defects in fetuses and newborn infants as well as neurological complications in children and adults
- Asymptomatic Zika virus infection in blood donors can pose a risk to the blood supply
- cobas Zika test expands Roche's industry-leading donor screening portfolio for blood-borne diseases in the CE market
PLEASANTON, California, Dec. 16, 2019 /PRNewswire/ -- Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced the CE-IVD launch of the cobas® Zika test for use on the cobas® 6800/8800 Systems. The cobas Zika test detects Zika virus RNA in samples of human plasma and is intended for use in screening blood donations. Building onto Roche's comprehensive menu of donor screening assays, this launch represents an important milestone in the effort to protect the blood supply from Zika virus globally. Recent news from French authorities reporting three cases of Zika infection apparently acquired locally1 highlights ongoing Zika activity and the need for blood bank preparedness solutions for tropical diseases.
The Zika virus is mainly spread through the bite of infected mosquitoes. However, it is suspected that infected donor blood used for transfusions could serve as an additional transmission route for the Zika virus.
"Together with cobas® CHIKV/DENV to screen for chikungunya and dengue viruses, the cobas Zika test provides a solution for preserving blood safety in regions with local outbreaks of these tropical diseases or from donors who may have been exposed while traveling to outbreak areas," said Mario Torres, Head of Roche Molecular Diagnostics. "Launching the cobas Zika test in markets accepting the CE mark expands the emergency preparedness solution for our customers and helps minimize the risk of transmission through infected blood and plasma donations."
Roche worked closely with the U.S. Food and Drug Administration to develop and launch the cobas Zika test in response to a public health crisis and ensure the safety of blood in the U.S. and its territories in 2017. Since then, the cobas Zika test has been used to screen millions of blood donations from the U.S. and Puerto Rico, helping to identify and remove more than 350 potentially infectious donations from the blood supply. Every year, there are more than 117 million blood donations worldwide.2 One blood donation has the potential to save as many as three lives, making a safe supply of blood and blood products extremely important for any patient that needs a transfusion.
About the cobas Zika test for use on the cobas 6800/8800 Systems
Manufactured by Roche, the cobas Zika test for use on the cobas 6800/8800 Systems is a qualitative in vitro nucleic acid screening test for the direct detection of Zika virus RNA in plasma specimens from donors of whole blood and blood components, and other living donors. Together with the cobas 6800/8800 Systems, the cobas Zika test provides solutions for blood services to detect the Zika virus and ensure that potentially infected blood units are not made available for transfusion. The fully automated cobas 6800/8800 Systems offer the fastest time to results with the highest throughput and the longest walk-away time available among automated molecular platforms, providing donor screening laboratories with improved operating efficiency and the flexibility to adapt to changing testing demands. The cobas Zika CE-IVD test is the latest addition to Roche's assay menu for donor screening laboratories — which includes cobas® MPX, cobas® DPX, cobas® HEV, cobas® WNV, cobas CHIKV/DENV and cobas® Babesia (FDA approved, not commercially available) — all of which run on the cobas 6800/8800 Systems. Not all assays are available in all markets.
Since 2014, the cobas 6800/8800 Systems have established the new standard for routine molecular testing by delivering fully integrated, automated solutions that serve the areas of donor screening, infectious disease, sexual health, transplant, respiratory and antimicrobial stewardship.
About the Zika virus
The Zika virus belongs to the Flaviviridae family of viruses, which includes dengue, yellow fever, Japanese encephalitis and West Nile viruses. Zika is mainly spread by the bite of infected mosquitoes; however, transmission through sexual intercourse and from pregnant mothers to fetuses has also been documented.3 A growing body of evidence confirms the links between Zika virus infection and defects in fetuses and newborns, as well as neurological complications in children and adults.4 Similar to other viruses in the Flaviviridae family, such as West Nile virus, it is suspected that infected donor blood used for transfusions could serve as an additional transmission route for Zika virus.5
