Epidemiological observation of cholera in rural kenya in 1983

Tropical Medicine 27(4): 229-240
Epidemiological observation of cholera in rural kenya in 1983
More than 17,000 rectal swab specimens were examined for Vibrio cholerae Ol at Cholera Laboratory in Homa Bay District Hospital. Out of these specimens, 1,301 cases were bacteriologically cholera-positive excluding repeated specimens. The number of admitted cases and healthy carriers were 788 and 513 respectively. Infection rate of cholera was lowest in the age-group, 13-19 of male. It was highest in female of childbearing age-group (15-39). Monthly variation of cholera-positive cases showed two peaks in March and July, closely correlated with the dry season. Monthly variation of cholera by age-group also showed two peaks in March and July. The former peak was formed by the age-group of 20-39 and the latter was by 13-19. High infection rate was found in Karachuonyo and Kanyada. The mortality of the admitted cases was 9%. One hundred and sixty-one cases were thought to be caused by family contacts, however most of the others were sporadic cases. Tetracycline resistant strains were isolated in 1982 even in Kenya, though the number was small. Most of the strains isolated in 1983 were resistant to multiple antimicrobial agents as well as O/129 which is a vibriostatic agent.
