"Prevention of Dengue Fever

The survey was conducted between 5 and 27 December 2002. A total of 3 024 people, aged between 15 and 64, were interviewed, representing a response rate of 79%. Major findings are as follows -

  • The majority (96%) of the respondents were aware of the threat of dengue fever and that over 60% of them realised preventive measures through various kinds of channels.

�@

  • The respondents were asked 10 true or false questions on knowledge about dengue fever. 83% of the respondents could answer at least six questions correctly. The median number of correct answers was seven.

  • It was found that less than half of the respondents knew that there was no vaccine against the disease, that dengue virus could be transmitted to its next generation, and that a fine would be imposed for those who allowed mosquito breeding by not removing stagnant water.

  • Nearly all (96%) respondents knew at least one type of anti-mosquito measures. The most commonly mentioned measures were ��remove stagnant water�� (81%), ��apply mosquito repellents on body�� (31%) and ��keep the environment clean�� (27%).

  • About 42% of the respondents said that they had taken anti-mosquito measures in the past 3 months. The most commonly practised measures were applying mosquito repellents and removing stagnant water. The main reasons for their inaction were ��no need�� and ��no mosquito around��.

  • It was also found in the survey that the knowledge level of the respondents was positively related to their level of practice of anti-mosquito measures. However, the link between knowledge and practice was not strong.

  • 45% of the respondents had witnessed stagnant water removal measures undertaken in the past three months. The locations where such activities were seen included areas near home (14%), parks/recreation areas (9%), construction sites (7%), wet markets (4%), hillsides (3%) and schools (3% among students).

  • 55% of the respondents were either very satisfied or satisfied with the anti-mosquito measures taken by the Government. For the rest, 40% gave an ��average�� rating, 5% were not satisfied and the others had no opinion. The level of satisfaction was related to the respondents�� witness of any stagnant water removal. Those who had witnessed so were about 1.2 times more likely to be satisfied than those who had not.

  • The majority of the respondents (78%) were of the view that the Government should continue to strengthen these measures, including cleaning of dirty spots (31%), promotion campaigns (25%) and law enforcement (4%).

  • 93% of the respondents considered themselves having a role in the fight against mosquito, particularly through keeping the environment clean.

  • It was also found that young people and students had better knowledge about the disease but poorer level of practice. The levels of knowledge and practice were in general lower among residents of public housing estates, and those unemployed or retired.
