WHO Launches CoViNet for Global Coronavirus Surveillance

WHO Launches CoViNet for Global Coronavirus Surveillance

The World Health Organization (WHO) has initiated a global network of laboratories to identify and monitor potential novel coronaviruses. This network, named CoViNet, expands beyond SARS-CoV-2 to include other coronaviruses such as MERS-CoV, with enhanced laboratory capacity.

Expansion of WHO’s Focus

Building upon the WHO COVID-19 reference laboratory network established in January 2020, CoViNet now incorporates animal health and environmental surveillance. This expansion aims to provide timely risk assessment to inform WHO policies and protective measures.

Support for Low- and Middle-Income Countries

CoViNet will facilitate the establishment of additional laboratories in low- and middle-income countries to monitor MERS-CoV and other novel coronaviruses of public health significance.

Objectives of CoViNet

Dr. Maria Van Kerkhove, acting director of WHO’s department of epidemic and pandemic preparedness and prevention, emphasized CoViNet’s role in ensuring timely detection, monitoring, and assessment of coronaviruses posing public health threats.

Composition and Scope of CoViNet

CoViNet comprises 36 laboratories from 21 countries across all six WHO regions. Notably, three Indian laboratories are included: the Council of Scientific and Industrial Research-National Environmental Engineering Research Institute, the Indian Council of Medical Research-National Institute of Virology in Pune, and the Translational Health Science and Technology Institute.

Action Plan and Future Initiatives

Representatives of CoViNet laboratories finalized an action plan for 2024-2025 during a meeting in Geneva, Switzerland. This plan aims to address health challenges posed by novel coronaviruses through coordinated surveillance and response efforts.

Utilization of Data

Data obtained through virus sequencing and surveillance activities will guide WHO’s Technical Advisory Groups on Viral Evolution and expert advisory groups on COVID-19 vaccine composition.

Warning on ‘Disease X’

WHO Director-General Tedros Adhanom Ghebreyesus cautioned about the possibility of future outbreaks akin to COVID-19, emphasizing the concept of ‘Disease X’ as a placeholder for an unknown disease of significant magnitude, likely to be zoonotic and RNA-based.

Coronavirus Variants and History

Coronaviruses encompass a broad family of RNA viruses, with some causing mild illnesses such as the common cold (e.g., OC43, HKU1) and others, like SARS-CoV, MERS-CoV, and SARS-CoV-2, leading to severe and sometimes fatal diseases.
