As Director of Medical and Health Services of Hong Kong, preventing and controlling infectious diseases had become his prime objective. When the territory was twice hit by cholera outbreaks between August and October 1961 and 1962, he adopted a number of effective emergency measures to combat the disease, such as to set up a temporary cholera hospital and a quarantine station-cum-isolation camp, and more importantly, set up a large number of vaccination points in the territory to urge the public to receive free vaccinations. Besides, to satisfy the ever-growing demand, he rapidly expanded the public health system by constructing a number of large-scale hospitals and public health facilities including the North Wing of Kwong Wah Hospital and Queen Elizabeth Hospital.
