The number of people with dengue has crossed the five figure mark with 10,258 cases diagnosed by 3pm on Monday.
But the rise in infections appear to have plateaued last week, with 813 cases - or two fewer than the week before.
Minister for the Environment and Water Resources Vivian Balakrishnan had said last week that projections by the National Environment Agency had predicted 960 cases last week.
Singapore has just entered the hot season when mosquitoes breed faster and are more able to spread the disease.
This morning, Dr Leo Yee Sin, head of the Communicable Disease Centre, said it was likely for the number of cases to exceed 15,000 this year.
