Focus Taiwan reported Friday that unless the number of cases comes down in September, Taiwan is on track to see the worst outbreak of the disease this year since records began in 2003, surpassing the current record of 15,942 cases, which was set last year.

At least 10 dengue-related deaths have been reported with several others under investigation.

One effort being undertaken to get the mosquito population under control is to breed the once endemic rice fish.

Researchers with the National Cheng Kung University (NCKU) and National Taiwan Ocean University (NTOU) have been breeding the fish that consume the larvae of mosquitoes in Gongliao District.

“Breeding the rice fish and introducing them to counties across the country with dengue outbreaks may help control the problem, NTOU professor of marine biology and environmental science Chen Yi-hsiung said.


The dengue fever outbreak in Malaysia continues to grow by several hundred daily. The current total cases now stands at 82,182, including 219 deaths.

Selangor state accounts for more than 45,000, or 54% of the country’s cases.
