Over 30 citations have been issued to property owners, giving them seven days to clean up their premises to avoid the breeding of mosquitoes or face a $3,500 fine.

Health Minister Terrence Deyalsingh spoke at a briefing days after he revealed that authorities would be ramping up the issuing of citations and, potentially fines, under the amended Yellow Fever Regulations.

Officials said the dengue-carrying mosquitoes breed in clean, stagnant water and common breeding sites include water barrels, old tires, plant pots, clogged drains or guttering and open/discarded containers.

Mr Deyalsingh insisted that reduction of mosquito breeding sites is primarily a domestic issue.

Mr Deyalsingh also responded to questions about the use of genetically modified mosquitoes to suppress the aedes aegypti mosquito.

Meanwhile, Epidemiologist Dr Avery Hinds noted that there has been a steady increase in cases from February to June with the peak in June at 98 cases.
