KAUST researchers suggest antibody testing can complement PCR tests to reduce false negatives in COVID-19 diagnosis. PCR tests can produce false negative results. Immunodiagnostic tests could help identify unknowingly spreading the disease. Why it matters: Improving diagnostic accuracy is critical for effective pandemic control and public health management in Saudi Arabia and globally.
KAUST's Rapid Research Response Team (R3T), including Professor Samir Hamdan, is working to understand and counteract the spread of COVID-19. The team assembled a complete homemade, one-step RT-PCR test, comparable to commercial kits, with a patent-free manufacturing recipe. KAUST R3T is also researching faster, more accurate point-of-care tests, including a CRISPR-based molecular test. Why it matters: This research provides accessible testing solutions and contributes to more effective and rapid detection methods for combating viral spread in the region and globally.
KAUST professor David Ketcheson uses mathematical modeling to understand COVID-19 transmission. He applies differential equations to explain the progression of SARS-CoV-2, utilizing the SIR model to predict the spread. Ketcheson's analysis suggests that the reproduction number for COVID-19 could be as high as 5, emphasizing the need for social distancing. Why it matters: This highlights the role of mathematical modeling and data analysis in understanding and predicting the spread of infectious diseases, particularly in the context of pandemic response.
KAUST researchers developed a new model integrating SIR compartment modeling in time and a point process modeling approach in space-time, also considering age-specific contact patterns. They used a two-step framework to model infectious locations over time for different age groups. The model demonstrated improved predictive accuracy in simulations and a COVID-19 case study in Cali, Colombia, compared to existing models. Why it matters: This model can assist decision-makers in identifying high-risk locations and vulnerable populations for better disease control strategies in the region and globally.
KAUST researchers are developing iSCAN, a rapid, field-deployable COVID-19 test using RT-LAMP coupled with CRISPR-Cas12. The iSCAN system is designed for rapid, specific detection of SARS-CoV-2 and can be deployed by untrained personnel. The researchers are benchmarking iSCAN against commercial kits and seeking emergency use authorization from the Saudi FDA. Why it matters: A rapid, accurate, and field-deployable COVID-19 test could significantly improve pandemic management and control in Saudi Arabia and beyond.
