Quest Diagnostics Introduces Testing for Oropouche Virus

Rhea-AI Summary

Quest Diagnostics (NYSE: DGX) has announced the launch of a new diagnostic laboratory test for the Oropouche virus, an emerging infectious disease prevalent in South and Central America and the Caribbean. The test, developed at Quest's San Juan Capistrano laboratory, will be available with a prescription by the end of July 2025.

The diagnostic solution employs PCR technology for early-stage detection, with serology testing planned for later in the quarter. This development follows Quest's CDC contracts awarded in September 2024 to support testing readiness for emerging infectious diseases. The initiative demonstrates Quest's role in preparing the U.S. healthcare system for potential public health threats.

[ "Development of first commercial diagnostic test for Oropouche virus in response to CDC contract", "Expansion of testing capabilities with both PCR and upcoming serology testing options", "Strategic positioning for potential public health threats through CDC contract funding" ]

Positive

• None.

Negative

• Limited immediate market potential as current U.S. cases are restricted to travelers
• Test requires prescription from healthcare provider, limiting direct access

Diagnostic testing for emerging infectious disease associated with severe neurological affects

SECAUCUS, N.J., July 15, 2025 /PRNewswire/ -- Quest Diagnostics (NYSE: DGX), a leader in diagnostic information services, today announced the launch of a new diagnostic laboratory test for the Oropouche virus, an emerging disease that is increasingly found in South and Central America and the Caribbean.

"As one of the leading providers of laboratory testing, Quest plays an essential role in ensuring the U.S. is prepared to respond to potentially dangerous emerging diseases, such as Oropouche virus," said Yuri Fesko, MD, Senior Vice President and Chief Medical Officer at Quest Diagnostics. "By developing this test, we are prepared to act quickly to offer scalable testing to complement public health labs should this virus become a public health threat."

Oropouche virus is an emerging virus in the Americas that is spread to people by infected biting midges and some mosquito species. While the current threat to the public in North America remains low, Oropouche virus has been reported in parts of South America, Central America and the Caribbean, with the majority of infected individuals becoming symptomatic. Cases reported in the United States have been limited to travelers returning from countries with local transmission. Oropouche viral disease presents clinically with symptoms that overlap with those of other arboviral diseases such as Dengue, Zika and chikungunya. While most people recover on their own, Oropouche virus can also cause more severe neuroinvasive disease like meningitis and encephalitis.

The test will be available with a prescription from a provider for clinical purposes at the end of the month. Quest's advanced laboratory in San Juan Capistrano, California, developed and will perform the test using polymerase chain reaction (PCR) technology, with serology testing to follow later this quarter. Reverse transcription PCR testing can identify the RNA of the virus during the early stages of infection to aid diagnosis. Serology testing, which identifies antibodies produced by the immune system in response to the virus, can help diagnose the virus in later stages of infection.

In September 2024, Quest Diagnostics was awarded several contracts by the U.S. Centers for Disease Control and Prevention (CDC) to support testing and sustained laboratory readiness for emerging infectious diseases, including the development of diagnostics to aid the detection of Oropouche virus. The company also launched the first commercially available diagnostic test for Avian Influenza A H5 based on the funding. The contracts provide funding to enable the company to maintain testing readiness, such as for adequate supplies of certain equipment and chemical reagents used to perform the tests, on a sustained basis, should the U.S. need to quickly mobilize response to safeguard public health.
