MERS-CoV virus isolate added to the WHO BioHub System, enabling further research and pandemic preparedness

The recent addition of a Middle East respiratory syndrome coronavirus (MERS-CoV) isolate to the World Health Organization’s (WHO) BioHub System marks a pivotal advancement in enhancing global pandemic preparedness. This development comes at a time when research on high-impact coronaviruses has gained paramount importance due to the experiences from past outbreaks and the ongoing challenges of emerging infectious diseases.

### Main Keyword: MERS-CoV

MERS-CoV, notorious for its zoonotic transmission primarily through dromedary camels to humans, poses significant health risks. Since its identification, the virus has led to sporadic outbreaks, with a staggering fatality rate of approximately 37%. Currently, there are no licensed vaccines or therapeutics to combat MERS, amplifying the urgency for robust research capabilities.

### The WHO BioHub System

Initiated during the COVID-19 pandemic under the directive of WHO’s Director-General, the BioHub System facilitates voluntary sharing and requesting of biological materials that possess epidemic or pandemic potential. The addition of the MERS-CoV isolate offers researchers unprecedented access to a virus that has been historically elusive, given that most prior research utilized clade A isolates, which have not been reported since 2015.

The current isolate is from clade C, which is still circulating in African camel populations, providing crucial data for understanding the virus’s evolution and potential risks it poses to humans. Dr. Maria Van Kerkhove, Acting Director of WHO’s Epidemic and Pandemic Management Department, emphasized that the BioHub’s facilitation of timely access to biological materials would significantly bolster research efforts, ultimately improving pandemic preparedness.

### Importance of Collaboration

The WHO BioHub System’s value lies not just in its capacity to share biological materials but also in fostering collaboration across borders. As of now, 76 laboratories from 30 countries have participated in the BioHub, highlighting a significant engagement aimed at sharing materials related to epidemics and pandemics. The foundations of the BioHub ensure that the sharing process is not merely transactional; it encourages joint scientific projects, transparency, and equitable recognition among researchers.

This framework helps to address historical inequities in pathogen access, ensuring that laboratories in lower-resource settings are not excluded from critical research opportunities. This has the potential to democratize scientific inquiry and foster a more inclusive approach to global health challenges.

### The BioHub’s Historical Context

The BioHub has already established itself as a vital resource during the COVID-19 pandemic by providing access to various SARS-CoV-2 variants. Its efforts in sharing mpox materials during the 2023-2024 outbreak illustrate its adaptability to shifting public health needs, reinforcing the significance of rapid access to biological materials for effective research, surveillance, and response.

### Future Directions

Looking ahead, WHO plans to expand the BioHub System by creating facilities within each WHO region. This initiative aims to guarantee that all parts of the world have equitable access to crucial materials and can respond swiftly to future health threats. The current central facility in Switzerland’s Spiez Laboratory is responsible for storing, characterizing, and distributing these materials, but broader regional networks are essential for a global response to infectious diseases.

Moreover, expanding capacities will boost biosafety and biosecurity measures worldwide, underscoring the importance of safe handling and sharing of pathogens.

### Conclusion

The inclusion of the MERS-CoV isolate into the WHO BioHub System represents a significant leap in pandemic preparedness and research facilitation. Through equitable and transparent sharing practices, the BioHub is setting a gold standard for future global health initiatives. As we move forward, fostering collaborations and ensuring equitable access to these critical resources will be vital in our collective efforts to mitigate the impact of infectious diseases and protect public health globally.

In an increasingly interconnected world, the imperative for timely and reliable access to biological materials has never been clearer. MERS-CoV, amid its challenges, presents an opportunity for renewed vigilance and partnership in global health security. The BioHub System not only reflects a response to past pandemics but is also a proactive step towards a more prepared and resilient global health landscape.
