RESUMO
Hepatitis B markers were tested for in 2001 samples of serum from those aged 0-21 years. There was a prevalence in Europeans of hepatitis B of 10% with a 2% of HBsAg carriage rate. For Maoris the prevalence was 25% with a 6% HBsAg carriage rate. The highest carriage rate was in the northern districts.

Isolation rates for herpes simplex virus types 1 and 2, recovered from oral and genital specimens submitted to the National Health Institute by clinicians within the Wellington region, were compared for two time-periods, 1971 to 1973 and 1981 to 1982 inclusive. The proportion of type 1 isolates from genital sites has increased from 4% to 11%, while conversely the proportion of type 2 isolates from oral sites has increased from 6% to 24%. Possible explanations for these trends are considered and the clinical and epidemiologic significance of this changing pattern is briefly discussed.

From late 1979 to 1981 there was an outbreak of rubella in New Zealand, most parts of the country being affected. The diagnostic virus laboratory at the National Health Institute, Wellington, examined approximately 15 000 sera for rubella during this period. The total number diagnosed as positive for rubella was 186. The extent of the outbreak was seen when these numbers were compared with rates of positive cases/numbers tested in the year from 1973. Of those diagnosed as having rubella infection, 63 percent were women of child-bearing age and approximately half of these (37 percent) were in various stages of pregnancy. Also an assessment of rubella immunity in New Zealand was made, comparing results of a survey carried out in 1976-1977 with antibody levels obtained by the laboratory from sera tested in 1979 and 1980. In 1980 we found that 12 percent of women in the child-bearing age group lacked adequate immunity, notwithstanding an actively pursued national rubella immunisation programme initiated in 1970.

Sera from 622 patients received in a 20-month period were examined for coxsackie B neutralising antibody to serotypes 1--6. Two hundred and thirty-four of the total 622 were patients with a cardiac symptomatology, and 388 formed a comparable group of non-cardiac cases. There were 141 (60 percent) seropositive patients in the cardiac group, 34 percent and 29 percent of which respectively had antibody to B4 and B2. The clinical data provided on these 141 patients indicated that 33 (23 percent) had acute myocarditis, and 59 (42 percent) had acute pericarditis; 41 (29 percent) were recorded as having acute pleurodynia or Bronholm disease while eight (6 percent) had other indications of cardiac disease. Amongst the cardiac patients the highest prevalence of seropositivity was found in the 20--39 age group and 67 percent of these were males.
