A multinational big data Covid-19 Epidemiological Study on post infection Outcomes (ACESO)

  • This is a multinational study with collaborations from USA, Australia, UK, Taiwan, Korea, Finland and Netherlands to investigate the long-term outcomes of COVID-19 on individual patient as well as on population as a whole. 
    Principal Investigator: Professor Ian Wong, Funding: HK$9,691,060

Effectiveness of single and combined anti-COVID-19 drugs among hospitalized COVID-19 patients in Hong Kong

  • The objective of this study is to evaluate the effectiveness of single and combined antiviral therapies in treating hospitalized patients confirmed with COVID-19 infection in Hong Kong, measure potential effects of adjunctive drugs, and assess post-discharge adverse events among COVID-19 patients. 
    Principal Investigator: Dr. Carlos Wong, Funding: HK$482,960

The role of smoking on the regulation of ACE2-mediated infectability of COVID-19

  • The broad goal of this research is to exploit how the expression of angiotensin-converting enzyme 2 (ACE2) is regulated in airway epithelia under smoking in vitro and in vivo before and after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Emphasis will be placed on its roles in viral replication and renin-angiotensin system (RAS) in relation to disease severity. 
    Principal Investigator: Dr. Judith Mak, Funding: HK$1,997,000
