The incidence of asthma amongst Tristan da Cunha islanders was recorded over a period of 16 months. Thirty‐two per cent of the islanders gave a history of asthma, and 22% had one or more attacks during the survey period. Three‐quarters of the affected islanders had mild asthma. Both the incidence and severity of asthma on Tristan have declined since 1944. 
Asthma prevalence in Tokelauan children in two environments
The prevalence of asthma has been studied in Tokelauan children aged 0–14 years in two environments—Tokelau and New Zealand. Only 11.0% of the 706 children examined in Tokelau were classified as

In Search of the Genes of Asthma on the Island of Tristan da Cunha
The University of Toronto Genetics of Asthma Project sent a team to the island of Tristan da Cunha to construct a geneology, obtain a history of respiratory and allergy symptoms by questionnaire, perform allergy skin testing and methocholine challenge, and obtain blood for white cell genetic studies.
Presentation of patients with asthma at an allergy clinic in Cape Town.
Asthma in Coloured patients started later in life than in Whites and seasonal asthma was more frequent in the former group, while Precipitating factors, the pattern of skin-prick test reactivity, the severity of asthma and its treatment were similar in the two groups.
The nature of asthma in Brisbane
Asthma in Brisbane was shown to be similar in many ways to asthma in those centres; however, a higher frequency of positive immediate skin test reactions to antigens of A. fumigatus, a larger percentage of skin test‐negative patients developing symptoms before the age of 10 years, and a lack of association between theAge of onset of symptoms and number of positive skin tests was noted.
Role of viral infections in the inception of asthma and allergies during childhood: could they be protective?
Two articles in this issue of Thorax compare the prevalence of asthma in different population samples and find significantly lower prevalence rates of asthma and allergic sensitisation in Chinese children living in mainland China than in children of similar origin living in westernised Hong Kong.
The incidence and causative factors of atopic asthma and rhinitis in an Orkney farming community
Sex distribution confirms the finding that males suffer from asthma more frequently than females, however more females than males give positive skin tests without exhibiting symptoms of allergy, which calls in question the validity of epidemiological studies of allergic disease based on hospital and clinic attendances.
Asthma and atopy – the price of affluence?
The impact of environment and lifestyle, particularly from the perspective of the East–West gradient, on the development of atopic diseases is outlined, with a special emphasis on the hygiene hypothesis in its broadest sense.

The unexpected presence in Britain of the whole Tristan da Cunha community gave a unique opportunity to study this inbred group, but the picture was more that seen in an underdeveloped country where, of necessity, continuous medical care and public health were difficult to achieve.
