In 2005, there were a total of 13,984 dengue fever cases and 19 people died. The outbreak peaked in the months of September and October, when it caused hospitals to cancel some elective surgery due to the need to allocate more beds for dengue patients.
Dengue fever is transmitted to humans by the mosquito Aedes aegypti. The virus can cause fever, severe headache, joint and muscular pains, vomiting, diarrhea and rashes. There is no commercially ready vaccine for dengue.
Singapore's health-care system is helping to maintain a low fatality rate at 0.1% (2005), which is lower than Southeast Asia's regional average of 0.8% in 2004, according to the World Health Organization.
The National Environment Agency said that the dengue fever problem may be worsening because of higher temperatures and changes in viral strains. The mean temperature has risen to 28.2 °C (82.8 °F) from 27.8 °C in 2003.
In the second week of September, more than 100 new cases were reported daily and many were admitted to public hospitals.
Health Minister Khaw Boon Wan said that one of the concerns is that more Singaporeans are infected with Dengue Type 3, which is a new strain of the dengue virus.
Some experts, such as Dr Paul Reitner, Professor of Entomology at the Pasteur Institute in France, suggested that Singapore's success in suppressing the dengue has partly contributed to this year sudden increase in dengue cases. The population born over the last two decades has a low herd immunity and therefore more susceptible to the virus.

“The influx of women into paid work and her increased power raise a woman’s aspirations and hopes for equal treatment at home. Her lower wage and status at work and the threat of divorce reduce what she presses for and actually expects.”
