简要总结
Develop an emergency PanorOmics Wide Association Study (ePWAS) for the early, rapid biological and pathophysiological characterisation of known and novel Infectious Diseases in adult patients presenting to emergency departments with suspected, acute, community-acquired respiratory infectious disease (scaRID).
Phase 1
- Develop an ED-ID biobank (named ePWAS-RID). Phase 2
- Targeted research for the discovery of novel diagnostics, prognostics and therapeutics
详细描述
Introduction
Pandemic Preparedness
The COVID-19 pandemic has affected over 220 million people, claimed over 450 000 lives and invoked variable responses across the world. Delays in acquiring quality clinical and scientific material on the transmissibility, clinical nature, outcomes and lethality of novel and known infectious diseases (ID) translate into healthcare inefficiencies, societal and economic stress, and increased morbidity and mortality. Regions with greater success in the fight against COVID-19 were well prepared before the pandemic.
Pathogens
The pathogens most likely to cause annual epidemics and pandemics are respiratory viruses. In Asia, viral infections account for 30-40% of sepsis cases. Each year there are 100 million cases of viral community-acquired pneumonia (CAP) of which 60% progress to sepsis. These viruses cause host-mediated, inflammatory, immune responses which progresses through three phases: preliminary regulated inflammation; intermediate dysregulated proinflammation; and late dysregulated hypoinflammation.
