Bhubaneswar, August 20: Odisha is witnessing a worrying rise in dengue and malaria cases, with health officials raising alarm over the increasing number of infections and changing mosquito patterns. A new species, Aedes albopictus-commonly called the "tiger mosquito" -has been identified as a major dengue vector in Bhubaneswar, more aggressive and outdoor-dwelling than the previously known Aedes aegypti.
Health experts warn that albopictus can also spread chikungunya and filariasis, and breeds in clean water, making urban areas especially vulnerable.
In Khurda district alone, 410 dengue cases have been reported so far in 2024. Infections surged following the onset of monsoon:
June: 98 cases
July: 188
August (till now): 81
From April 23 to August 4, Bhubaneswar recorded 208 cases, with the Patia area being the worst hit (31 cases).
A 2023 RMRC study revealed Aedes albopictus was found 70% more frequently than Aedes aegypti in 14 city locations, posing a serious public health challenge. Despite this, awareness remains low — especially in slum areas, where poor sanitation and limited testing persist.
The city’s disease control efforts are strained due to manpower shortages. Only 25% of Bhubaneswar’s wards have ASHA workers. The newly formed City Programme Management (CPM) unit is operating with minimal staff, limiting outreach in high-risk zones.
"We are running strong awareness campaigns, but more work is needed in slums," said ADPHO Dr. Neelamani Senapati. Capital Hospital Director Dr. Roopabhanu Mishra added that a 10-bed dengue ward is operational but cannot be expanded due to space constraints.
Globally, only 6% of over 3,500 mosquito species feed on blood. Dengue symptoms typically appear 4–5 days after a bite.
Odisha dengue cases over the years:
2020: 4,496
2021: 7,548
2022: 7,063
2023: 12,845
2024 (so far): 9,892
Authorities urge the public to eliminate stagnant clean water sources and seek early treatment for fever symptoms.
