Type 1 dengue with hemorrhagic disease in Fiji: epidemiologic findings.

An explosive epidemic of dengue occurred in Fiji between January and July 1975. All laboratory evidence indicated that type 1 dengue was the only prevalent dengue virus. This type had probably not been in Fiji for 30 years and over 70% of the population was susceptible.

An Application Of Inferential Statistics To The Factorial Invariance Problem.

Attention has been drawn to the lack of standards for evaluating the degree of goodness of fit of patterns resulting from a principal components analysis of two data sets. An empirical sampling distribution of the statistic average trace (E'E), as E is obtained in the orthogonal Procrustes problem for various orders of A matrices was developed through a Monte Carlo approach. A method is presented which can be used as a guideline in determining whether factor is structures obtained from two data sets are congruent.

Mosquito-borne infections in Fiji. V. The 1971-73 dengue epidemic.

A dengue epidemic due to type 2 virus involving some 3,400 cases began in Fiji early in 1971, had a peak during May, June and July, and cases have continued to occur with a low incidence during 1972 and 1973. Many of the notified cases showed classical dengue fever symptoms and there were no confirmed cases of haemorrhagic fever. A serological survey indicated that there had been at least 20,000 subclinical infections.

A COMPARISON BETWEEN THE STRUCTURES OF DIVERGENT PRODUCTION ABILITIES OF CHILDREN AT TWO LEVELS OF INTELLECTUAL FUNCTIONINg.

Twelve divergent production tests were administered to 46 adolescents whose average WISC full scale IQ was 69.5 and t o a similar group of 48 adolescents whose average WISC full scale IQ was 104.6.

Mosquito-borne infections in Fiji. II. Arthropod-borne virus infections.

Surveys of arbovirus activity in Fiji were conducted over a 10-year period from December 1959 to December 1969. No arboviruses were isolated from over 200,000 mosquitoes, 9000 ticks, or 575 serum samples. Eight thousand human and 1117 bird, bat and animal sera were tested for haemagglutination-inhibiting arbovirus antibody using a variety of group A, group B and Bunyamwera group antigens.

The laboratory transmission of Coxsackie A6 virus by mosquitoes.

Coxsackie A 6 virus, strain V 29, originally isolated from Aedes polynesiensis in Fiji, was found to survive in A. australis for 5 days after intrathoracic injection and for 6 days after feeding on viraemic mice, and in Culiseta tonnoiri for 8 days after feeding.The virus level in both fed and injected mosquitoes fell steadily after infection and never exceeded the original level.
