A rapid assessment was carried out in
June 2007 to determine factors concerning
previous malaria infection as a part of the
epidemiological assessment to develop
practical preventive measures among the
migrants. Calculation of study sample size
was done from an available study in
Kanchanaburi (Sudathip, 1998). All houses
were assigned individual numbers, and
random sampling was achieved by computer
generated random numbers. A total
of 125 households were selected. Eligible individuals
were persons age 15 years old and
above who had lived in the village for at
least three months. In each household, the
head of the household and the spouse or
another family member were interviewed.
Out of 214 respondents, only 22 were Thai;
90 respondents belonged to the Mon and
102 to Karen migrant group. Information
was collected with structured, pre-tested
questionnaires by trained interviewers. Interpreters
for the Mon and Karen languages
were provided throughout the study. The
study was approved by the ethics committees
of the Department of Disease Control,
Ministry of Public Health, Thailand, and the
Faculty of Tropical Medicine, Mahidol University.
Respondents gave informed consent
before being included in the study.
