Research 

 

Research Areas

 

Dr. Chiu’s research focuses on:

1. Influenza and influenza immunization

2. Other viruses

3. Epidemiology of bacterial respiratory infection

 

1. Influenza and influenza immunization

Dr. Chiu established the association of influenza A with febrile seizure in children. In collaboration with Prof Malik Peiris, she was the first to document the population-based pediatric influenza disease burden in the subtropics. Since then, she has continued to study and publish on influenza infection in children. Her work has also included 2 randomized controlled intradermal vaccination trials in children in an effort to explore dose-sparing regimens.

 

2. Other Viruses

She has published on different respiratory viruses infecting children.
 

3. In collaboration with Dr. PL Ho, she has studied and published on the epidemiology of bacterial pneumonia in Hong Kong children, with an emphasis on the study of Streptococcus pneumonia.
