Dengue Fever Cases Surge in Sri Lanka Amid Worrying Trends

Strategic Insights -

The National Dengue Control Unit (NDCU) of Sri Lanka's Health Ministry has sounded an alarm, warning of an expected increase in dengue fever cases in the coming weeks due to people's decreasing concern over prevention during the wet weather. According to the NDCU, the Western Province accounts for nearly half of all dengue cases across the country, with 11,028 cases (38.2%) reported. As of the first week of July, a total of 28,868 dengue patients and 11 reported deaths were recorded nationwide. The NDCU expects a surge in cases in several districts, including Gampaha, Kalutara, Ratnapura, Kegalle, Kandy, and Galle, as well as in Colombo.

Key Takeaways:

  • The NDCU expects a surge in dengue cases in the Western Province, particularly in Gampaha, Kalutara, Ratnapura, Kegalle, Kandy, and Galle, as well as in Colombo.
  • The Western Province accounts for nearly half (38.2%) of all dengue cases across the country, with 11,028 recorded cases as of the first week of July.
  • A total of 28,868 dengue patients and 11 reported deaths were recorded nationwide as of the first week of July.
  • Mosquito populations adapt quickly to urban environments, making complete elimination challenging, with species like Aedes aegypti and Aedes albopictus displaying remarkable adaptability.
  • Urbanisation has worsened the challenge of mosquito control, creating ideal breeding grounds in unplanned settlements with inadequate sanitation and drainage systems.
  • Construction-related building materials, such as expanded polystyrene (EPS) packaging, pose a risk of mosquito breeding if not properly disposed of.
  • Overuse and misuse of insecticides have contributed to the development of resistance in mosquito populations, necessitating alternative strategies and judicious use of insecticides.
  • Climate change has altered temperature and precipitation patterns, influencing mosquito distribution and behavior, potentially increasing transmission rates.
  • A multi-faceted approach, including environmental modification, biological control, chemical control, and community engagement, is required to combat mosquito-borne dengue fever.

Statistics:

  • 11,028 dengue cases (38.2% of total cases) were reported in the Western Province as of the first week of July.
  • 28,868 dengue patients and 11 reported deaths were recorded nationwide as of the first week of July.
  • The majority of dengue cases (6,535) were reported from the Colombo District.
  • A total of 2,907 (10.1%) cases were reported from Gampaha District and 1,586 (5.5%) from Kalutara District.
  • Mosquitoes can breed in small amounts of stagnant water found in urban areas, such as discarded tyres, flower pots, and gutters.
  • Female mosquitoes can lay eggs multiple times during their lifespan, with each batch capable of producing hundreds of larvae.
