Alveo Technologies, Inc. (Alveo), a leader in molecular sensing and diagnostics, has announced a significant advancement in its avian influenza diagnostic capabilities. The company has demonstrated through in silico analysis that its rapid, handheld point-of-need molecular diagnostic can accurately detect the H5N1 avian influenza variant, utilizing genetic sequences from recent infections in Colorado.

On July 15 and 16, the Global Initiative on Sharing All Influenza Data (GISAID) released the genetic sequence of H5N1 viruses that recently infected a dairy farm worker in Colorado. This release highlighted a “mammalian adaptation marker (E627K)” in the virus, raising concerns about its potential for efficient human transmission. The method of transmission among cattle remains unclear, but there is apprehension that the virus could reintroduce into poultry or adapt further to humans, increasing the risk of widespread transmission.

The urgency of increasing testing capacity for avian influenza is underscored by recent outbreaks. The UK Health Security Agency noted in May that the risk of H5N1 evolving to cause human transmission has risen from a previously remote chance to a more concerning level. The agency suggested that while current data are limited, the risk might be categorized as either highly unlikely (10-20%) or unlikely (25-35%).

In response, Alveo has conducted in silico analysis using their Avian Influenza A subtype H5 LAMP designs on recently reported sequences from both humans and cattle. Results indicate that Alveo’s H5 designs are compatible with all 12 reported sequences of emerging influenza A subtype H5, suggesting that their assay can detect these variants effectively. This capability is crucial as it ensures that the diagnostic tool remains relevant amidst evolving strains.

Alveo Technologies is set to advance its diagnostic offerings with the introduction of the Flockscreen LAMP Avian Influenza Molecular Test. This test, capable of analyzing both cloacal and oropharyngeal samples, is scheduled to begin shipping to Europe and the Middle East in the third quarter of 2024, following validation and regulatory approvals. Alveo is also working on expanding the validation of its diagnostics to include human and bovine use cases.

Shaun Holt, CEO of Alveo Technologies, emphasized the critical need for rapid and precise diagnostics to address avian influenza’s impact. Holt highlighted that the company’s portable and rugged diagnostic platform could significantly enhance the detection of the H5N1 virus in diverse settings, including both field and laboratory environments. He stressed the importance of swift, accurate diagnostics to prevent further evolution of the virus and mitigate its potential spread among humans and animals.

Alveo Technologies’ advancements in avian influenza diagnostics come at a crucial time, with rising concerns over the H5N1 virus’s potential for increased human transmission. The company’s rapid, portable diagnostic solutions offer a promising tool for addressing this urgent public health challenge. As Alveo continues to develop and validate its technology, the integration of such innovative solutions will be vital in managing and preventing the spread of avian influenza.
