In recent months, India’s efforts to sequence the genomes of COVID-19 variants have experienced a significant decline, resulting in a lack of updated information on the circulating variants of the virus. The India SARS-CoV-2 Genomics Consortium (INSACOG), a collaborative initiative by the Union Health Ministry of Health, the Department of Biotechnology, the Council for Scientific and Industrial Research (CSIR), and the Indian Council of Medical Research (ICMR), has not released any bulletins since March 27.
INSACOG’s Role and Significance:
The India SARS-CoV-2 Genomics Consortium (INSACOG) is a joint program aimed at monitoring genomic variations in the SARS-CoV-2 virus. Comprising 54 laboratories across India, INSACOG plays a crucial role in identifying and studying new, potentially dangerous variants of the virus. By regularly publishing bulletins, INSACOG used to provide valuable information on circulating variants, surge areas, and the presence of globally identified variants in India. Unfortunately, the absence of recent reports signifies a slowdown in sequencing efforts within the consortium.
Factors Contributing to the Decline:
Several factors could be contributing to the decline in genome sequencing of COVID-19 variants in India:
- Decreased sample availability: The number of samples being made available to network laboratories has reduced, hindering the ability to carry out comprehensive sequencing.
- Shifting priorities: With the decline in COVID-19 cases and the progress made in vaccination campaigns, the focus may have shifted from genomic surveillance to other public health aspects.
- Resource constraints: Sequencing genomes requires substantial resources, including advanced laboratory equipment, trained personnel, and financial support. Limitations in these areas may be impacting the sequencing capacity.
Implications of Reduced Sequencing Efforts:
The reduced genome sequencing of COVID-19 variants in India has several implications:
- Limited understanding of variant prevalence: Without up-to-date sequencing data, it becomes challenging to assess the prevalence of different variants and their potential impact on public health.
- Delayed response to emerging variants: Timely identification of new variants is crucial for implementing targeted public health measures and adjusting vaccination strategies. The lack of sequencing updates may impede the ability to respond promptly to emerging threats.
- Global implications: India’s significant role in genome sequencing makes the lack of updated information particularly concerning on a global scale. Collaborative efforts and information sharing are crucial for monitoring and controlling the spread of variants across borders.
The International Pathogen Surveillance Network (IPSN):
To address the challenges associated with pathogen surveillance and response, the World Health Organisation (WHO) has launched the International Pathogen Surveillance Network (IPSN). This global network aims to enhance global collaboration in protecting people from infectious disease threats through pathogen genomics. IPSN focuses on the following:
- Connecting countries and regions: IPSN provides a platform for connecting countries and regions, enabling improved systems for collecting, analyzing, and sharing samples and data related to infectious diseases.
- Data-driven decision-making: By utilizing pathogen genomics, IPSN aims to improve public health decision-making, helping countries respond effectively to emerging threats and tailor their interventions accordingly.
- Information sharing: IPSN emphasizes the importance of sharing information related to pathogen genomics on a broader scale. This promotes transparency, facilitates early detection of new variants, and enables collaborative efforts to mitigate the spread of infectious diseases.
