A seroprevalence survey of hepatitis B markers among Haitians in a southwest Florida farming community.

We determined the seroprevalence of hepatitis B virus markers among 123 Haitian mothers and children in a southwest Florida farming community. Fifty-five per cent of mothers had one or more markers including two who were HBsAg positive. Only seven (10 per cent) children had markers; none were HBsAg positive. Pregnant Haitian women should be screened for HBsAg and infants born to those who are positive should receive immunoprophylaxis. Medical, dental, and laboratory workers caring for Haitian patients should also receive hepatitis B vaccine.

Epidemic measles in a highly vaccinated population.

During November, 1975, to May, 1976, measles occurred at a rate of 20.3 cases per 1000 in a purported immunized population, of whom historical and serologic survey revealed that 9 per cent had no history of either measles illness or vaccination and 18 per cent did not have detectable measles antibody. Antibody was detectable in 92 per cent of those vaccinated at greater than or equal to 13 months, 80 per cent at 12 months and 67 per cent of those vaccinated when less than one year old (P less than 0.001), but no significant differences existed with increasing years since vaccination (P greater than 0.1). A second vaccination increased detectable antibody prevalence only in those originally vaccinated when less than nine months old (42 to 80 per cent, P less than 0.02). During a measles outbreak, more cases occurred in those receiving vaccine when less than 12 months old than in those vaccinated at greater than or equal to 12 months (37 per cent vs. 9 per cent, P less than 0.001). A second vaccination protected those originally vaccinated at less than 12 months (35 per cent ill without a second vaccination vs. 2 per cent with, P less than 0.001). Thus, a single measles vaccination of children less than 12 months old does not protect; a second vaccination will protect this group.

Drug and risk perception on ninth-grade students: sex differences and similarities.

Sixty-two secondary school students were observed in their classrooms over 5 weeks of intensive drug information for within-group changes in their perceptions. "Peer pressure" and "kicks" were cited as reasons for starting and using drugs; but peer pressure had relatively greater strength for girls than for boys, and curiosity increased for girls. Boys and girls differed in reasons for stopping drugs (peer and professional help for girls, and punishment for boys). In rating the relative dangers and pleasures of marijuana and heroin, most students did not discriminate effectively between the two drugs, although ratings of marijuana dangers decreased. Unexpectedly, responses concerning the health hazards of heroin did not increase. In a situation simulating risk under peer pressure, boys chose targets as appropriate for their skill as did the girls.
