Introduction

In a groundbreaking move, the World Health Organization (WHO) has authorized Abbott Laboratories' mpox diagnostic test for emergency use, marking a pivotal step in enhancing testing capabilities amidst rising outbreaks of the disease. The approval, granted on October 3, represents the first diagnostic test specifically for mpox to receive this designation under the WHO’s Emergency Use Listing (EUL) procedure.

The Alinity m MPXV Assay

The Alinity m MPXV assay, a real-time PCR test, is designed to detect mpox virus DNA directly from human skin lesion swabs. This innovation is critical as it allows trained clinical laboratory personnel to verify infections rapidly, significantly increasing the speed at which health authorities can respond to outbreaks. "This first mpox diagnostic test listed under the Emergency Use Listing represents a significant milestone in expanding testing availability in affected countries," commented Yukiko Nakatani, the WHO’s Assistant Director-General for Access to Medicines and Health Products.

Collaboration and Future Measures

In a statement, Abbott confirmed that it has the Alinity m mpox test ready for deployment and will collaborate with healthcare providers to meet their testing needs. This initiative comes at a crucial time as the WHO is also assessing three additional mpox diagnostic tests for emergency use and is in talks with various manufacturers to broaden the range of available testing tools.

Global Health Emergency Declared

The urgency for such measures arose after the WHO declared mpox a global public health emergency for the second time within two years, primarily due to a concerning outbreak in the Democratic Republic of Congo. This outbreak has swiftly spread to neighboring countries, including Burundi, Uganda, and Rwanda, amplifying the need for effective tracking and containment strategies.

Variants of Concern

Worryingly, there are two variants of mpox currently spreading: the clade I variant, which is traditionally found in parts of West and Central Africa, and a newly identified, more transmissible clade Ib variant that has caused international alarm. Notably, Sweden, Thailand, and India have already reported cases of the clade Ib strain, sparking fears of a broader pandemic.

Conclusion

As the world grapples with the resurgence of mpox, the WHO's swift action in approving diagnostic testing is not just a reactive measure but a proactive strategy aimed at averting further spread. The global health community eagerly awaits additional diagnostic tools and tests that could further enhance outbreak responses and protect populations worldwide.
