Health authorities warn that dengue risk persists in Sri Lanka even as case numbers have dropped significantly, with officials urging continued mosquito control efforts.
Sri Lanka's National Dengue Control Unit has cautioned that the country's dengue threat remains active despite a substantial reduction in reported cases over recent months. Dr. Prashila Samaraweera, a consultant specialist at the unit, made these remarks during a media briefing at the Health Promotion Bureau, emphasizing that the absence of a high case count does not indicate the disease has been eliminated.
The epidemiological pattern shows a marked seasonal decline in dengue transmission. According to official figures, Sri Lanka recorded 95,868 dengue cases through 2026, with peak activity in June (21,533 cases) and July (29,962 cases). August saw a significant drop to 10,156 cases, and as of early September, only 376 cases had been reported. The case fatality rate stands at 0.075%, with 72 deaths recorded to date. Authorities have identified 50 high-risk MOH areas, averaging 641 new cases daily.
Geographically, dengue concentration remains uneven across Sri Lanka. The Western Province accounts for over half of all cases at 52.80%, with Gampaha and Colombo districts leading at 20,415 and 18,981 cases respectively. Health officials note a concerning pattern in certain districts where increases in mosquito populations precede rises in patient numbers, suggesting potential for renewed transmission cycles.
Despite the declining trend, authorities stress that prevention remains essential. Dr. Samaraweera urged the public to eliminate mosquito breeding grounds in and around homes and workplaces, emphasizing that sustained vigilance is necessary to prevent resurgence.
