Risk factors, prevention and control performance of dengue haemorrhagic fever : a comparative study between districts with the highest and the lowesr incidences in Pathum Thani province
Abstract:
This study aimed to compare people’s knowledge, perception, prevention and
control practices concerning DHF, the presence of DHF cases in household,
environmental characteristics, larval indices (HI, BI) and health personnel’s DHF
prevention and control performance between the highest and the lowest incidence
areas in Pathum Thani. Furthermore, factors affecting the presence of DHF were also
examined. 300 people and 57 health personnel in the highest incidence and 300
people and 44 health personnel in the lowest incidence areas were randomly sampled
and interviewed from March to May 2003.
Overall knowledge, perception and prevention and control practices
concerning DHF of people in both areas were in need of improvement. Considering
individual aspects of each variable, people in the low incidence area had better
knowledge of DHF transmission (p=0.006), better perceived barrier (p<0.001) and
better practices in overall DHF prevention and control (p<0.001) than the people in
the high incidence area. In contrast, the high incidence area had a higher presence of
DHF cases in the household (p<0.001) and had higher larval indices than the low
incidence area (p<0.001). Furthermore, the environmental characteristics were prone
to DHF infection (p<0.001). Health personnel in the low incidence area analyzed
and evaluated DHF data during on epidemic period and reported a House Index (HI)
better than the opponent (p<0.05). Stepwise multiple linear regression identified
three determinants of the presence of DHF cases: households with high numbers of
family members, living in a higher risk community and those with a lower education
level. Continued health education and interventions to increase people’s awareness
regarding DHF prevention and control practice through community participation
were needed. Health personnel should receive reorientation and updated training on
DHF surveillance and report
