PUTRAJAYA: Consult the nearest government health clinic before letting private firms fog your premises during a dengue outbreak this is the Health Ministrys advice to the public.
Its disease control director, Dr Ramlee Rahmat, said there were criteria set to ensure that fogging was effective and did not result in adverse effects.
These, he added, covered the chemicals used and their composition, precautions people should take and the proper times for fogging between 6am and 8am and between 5pm and 8pm.
Improper use of chemicals can also result in the Aedes mosquitoes being more resistant to fogging later, he told a media briefing here yesterday.
Dr Ramlee said fogging was aimed at breaking the chain of transmission and the authorities would carry out fogging in an area once a dengue case had been reported.
The effects of proper fogging will only last about a week and it is still better to prevent the breeding of mosquitoes, Dr Ramlee said.
According to him, construction sites still topped the list of mosquito breeding grounds.
Of the 685 places found to be breeding grounds in the second week of January, 13% were construction sites, 8% factories and 7% vacant land.
Dr Ramlee said only between 30% and 50% of the suspected cases had been confirmed as dengue cases.
The recent surge in reported cases was due to the public alert on the outbreak, he said, adding that this was good for effective monitoring and control of the disease.
There were 1,416 suspected cases reported between Jan 8 and Jan 15 against 1,049 the week before.
Dr Ramlee said there were three dengue deaths between Jan 1 and Jan 15 a six-year-old child in Kuala Lumpur, a 46-year-old woman in Pahang and a 34-year old man in Malacca.
In Selangor, the Gombak and Shah Alam districts have recorded the highest number of cases this year as of Jan 15, with 337 and 119 cases respectively.
State Health director Dr Ang Kim Teng said the department had assigned a senior officer to coordinate daily prevention and control activities such as inspection of premises and fogging.
The department, she added, had mobilised staff from other districts and the headquarters to assist in running the awareness programme and to clear-up breeding sites in Gombak.
She said apart from residential areas, dengue cases had also been traced to government buildings and educational institutions.
We have recorded cases at the Gombak district police headquarters, International Islamic University Malaysia and Universiti Teknologi Mara, she said when contacted yesterday.
Dr Ang said so far 1,096 dengue cases had been reported in Selangor based on clinical diagnosis, of which 59 were cases of dengue haemorrhagic fever.
