Dhaka, Bangladesh — September 2025
Bangladesh is grappling with one of its most serious mosquito-borne disease crises in recent years, as both dengue and chikungunya cases rise sharply across major cities. The simultaneous spread of these two illnesses has pushed hospitals to their limits, creating overcrowded wards and a mounting challenge for healthcare workers.
Rising Numbers, Alarming Trend
Since the start of this year, more than 30,000 confirmed cases of dengue have been reported nationwide, with fatalities already crossing 100 deaths. In parallel, chikungunya — a disease that had been relatively under control in recent years — has suddenly resurfaced, with thousands of new cases being recorded in Dhaka, Chittagong, and other districts.
Doctors warn that the number of patients could increase even further during September and October, as the monsoon season and warm, humid conditions create ideal breeding grounds for mosquitoes.
Symptoms and Patient Experiences
Patients affected by dengue are experiencing high fever, severe headaches, muscle pain, rashes, and in some cases, internal bleeding. Chikungunya, meanwhile, is causing prolonged joint pain, fatigue, and recurring fever, symptoms that can linger for weeks.
Many patients report that this year’s fevers are lasting longer and are more intense than in previous years. The overlap in symptoms between the two diseases also makes diagnosis more difficult, increasing the risk of delayed treatment.
Strain on Hospitals
Hospitals in Dhaka and Chittagong are struggling to cope with the influx of patients. Wards designed for a limited number of beds are now overcrowded with patients lying in corridors, waiting areas, and makeshift beds. The shortage of intensive care units and blood supplies has further complicated treatment for severe dengue cases.
Healthcare workers, already under immense stress, are working long hours to manage the crisis. Some hospitals have set up dedicated fever wards, but the rising patient load continues to outpace available resources.
Why the Outbreak is Spreading
Several factors are contributing to the crisis:
- Urban overcrowding and poor drainage systems have created countless breeding sites for Aedes mosquitoes.
- Heavy rainfall and stagnant water in both cities and rural areas are fueling mosquito growth.
- Limited mosquito control programs and delayed interventions have allowed mosquito populations to grow unchecked.
- Public negligence, such as storing water in open containers and lack of protective measures, has worsened the spread.
Government and Community Response
Authorities have launched emergency vector-control campaigns, spraying insecticides in high-risk neighborhoods and urging citizens to clean waterlogged areas. Public health campaigns are advising people to:
- Cover water containers,
- Use mosquito repellents and nets,
- Wear long-sleeved clothing,
- Seek immediate medical attention for high fever or bleeding symptoms.
The government has also directed hospitals to increase bed capacity and prioritize treatment for patients with severe symptoms.
Looking Ahead
Health experts warn that without sustained mosquito-control measures and stronger hospital preparedness, the dual threat of dengue and chikungunya could escalate into one of the largest outbreaks in Bangladesh’s recent history. The coming weeks are considered crucial, as weather conditions remain favorable for mosquito breeding.
The crisis is a stark reminder of the urgent need for long-term urban planning, drainage improvement, public health education, and robust disease surveillance systems to prevent recurring outbreaks in the future.
