Health Diagnostics

Jacqueline Weyer of the National Institute for Communicable Diseases in South Africa and Jinal Bhiman of Wits Health Consortium (Pty) Ltd also in South Africa will leverage a rapid monoclonal antibody (mAb) isolation and screening pipeline to develop diagnostics that differentiate between pathogens to support epidemic responses. Africa’s burden of many zoonoses and vector-borne diseases (VBD), such as Lassa fever and yellow fever, remains largely unknown, mainly due to diagnostic costs and limited access to reagents.

Mai Le of the National Institute of Hygiene and Epidemiology in Vietnam will expand Vietnam’s systematic surveillance and sequencing capacities to detect potential pandemic pathogens, including influenza and coronaviruses, and incorporate agnostic sequencing of conventionally undiagnosed pathogens. They will build on the existing infrastructure of the influenza-like illnesses sentinel surveillance network, which collects samples from four outpatient clinics, to include testing for both influenza A and B and SARS-CoV-2 viruses, with the possibility to expand.

Chhorvann Chhea of the National Institute of Public Health in Cambodia will expand Cambodia’s Severe Acute Respiratory Infections (SARI) surveillance network by integrating metagenomic next-generation sequencing to better diagnose and monitor severe respiratory infections. Pneumonia is the leading cause of death globally in children under five years old, with the majority of severe cases classified as viral.

Audrey Dubot-Pérès of the Lao-Oxford-Mahosot Hospital-Wellcome Trust Research Unit (LOMWRU) in Lao PDR will establish a pilot respiratory syncytial virus (RSV) genomic surveillance system to determine disease burden and monitor strain circulation in Lao PDR. RSV is the leading cause of viral pneumonia in young children in low-income countries. Accurate data on disease burden, transmission and viral evolution are critical to successfully introduce emerging vaccines and therapies.

Orapan Sripichai of the National Institute of Health of Thailand in Thailand will engage a national network of laboratories for the genomic surveillance of Salmonella, involving sequencing clinical isolates to characterize strains, virulence factors and mechanisms of antimicrobial resistance. Salmonella infection is prevalent in Thailand and can be life-threatening. The emergence of multidrug-resistant Salmonella strains in Southeast Asia is an additional major concern.

Pragya Yadav of the Indian Council of Medical Research - National Institute of Virology in India will strengthen genomic and epidemiological surveillance in different locations across India to enhance preparedness against high-risk viral diseases. With India's extreme geo-climatic diversity, it is under constant threat of emerging and reemerging viral infections.

Rifky Waluyajati Rachman of the West Java Provincial Health Laboratory in Indonesia will employ targeted next-generation sequencing (NGS) to support genomic surveillance of drug-resistant tuberculosis (TB) in Indonesia. Indonesia has the second highest number of TB cases globally and a growing burden of largely undetected multidrug-resistant TB, yet no drug resistance surveillance in place. They will perform targeted NGS on over 5,000 positive sputum samples to more accurately estimate drug-resistant TB prevalence.

Project intends to identify highly specific, and tandem repeats in the genomes of W. bancrofti, B. malayii, B. timori, and other human filarial agents, to develop a field-deployable, diagnostically robust molecular Point-of-Care test for Lymphatic Filariasis detection.

Project intends to discover high affinity and specific ligands called suprabodies as the biomarkers of Lymphatic Filariasis.

Project intends to capture the images of blood samples for diagnosis of Lymphatic Filariasis and applying customized machine learning algorithms for quantification and classification of Lymphatic Filariasis.
