In 1921, 1922 and 1923, the Royal Air Force Sandfly Fever Commission Malta consisted of:
- 1921: Sqn Ldr Harold Edward Whittingham, Cpl G H Noakes, and Aircraftman 341189 R Stewart (June 1921).
- 1922: Sqn Ldr H E Whittingham MB DPH DTM, Flt Lt Alan Filmer Rook MRCP DPH, Cpl R Stewart, and 337215 Aircraftman H A Collett (1922).
- 1923: Wg Cmdr H E Whittingham, Cpl R Stewart and Leading Aircraftman H A Collett, all of the Royal Air Force Medical Service (May 1923).
On 22 April 1922, Sqn Ldr Whittingham and Flt Lt A F Rook were attached to HQ Mediterranean Group to resume their research on the causation of Sandfly Fever, which had commenced in Malta on June 1921.
A small laboratory was set up at Kalafrana in part of a disused old officer's mess. The co-operation of the Army Medical Staff in Malta had been obtained through the office of Lt Gen Sir William Leishman Director of Army Pathology. However, neither the Governor of Malta, nor the Civil Medical Authorities were informed of the arrival of the research party. The RAF medical services had instituted the research project primarily in the interests of the health and efficiency of RAF personnel only.
Sandfly Fever had been an important factor in the causation of non-effectiveness in the Royal Air Force. It was hoped that the research project would provide material which would help diminish the incidence of Sandfly Fever on flying stations.
On 26 April, Field Marshall Lord Plumer, who had only been informed of the arrival of the RAF Sandfly Fever Research team by the Officer Commanding Royal Air Force Mediterranean, made clear his views to the Colonial Office. He was of the opinion that the investigation into Sandfly Fever should be carried out by a conjoint civilian and military team, as the subject of Sandfly Fever was of equal importance to the Imperial Services, as well as the civilian population.
The RAF were not keen on this suggestion and wanted to retain control of their in-house project. The team returned to England at the end of August leaving Cpl R Stewart in Malta to collect specimens. Stewart returned to the Royal Air Force Central Hospital Finchley, on HMS Argus on 26 December 1922, where he continue working in the Pathological Laboratory under Sqn Ldr Whittingham.
