Patna: While Bihar has witnessed a decline in deaths caused by encephalitis, commonly known as Chamki fever, health experts say the state is still far from identifying the definitive causes behind the potentially fatal disease.
As temperatures rise and the annual season of encephalitis cases approaches, government departments have once again initiated preventive measures and awareness campaigns aimed at protecting children. However, experts point out that despite years of research and investigations, no conclusive scientific explanation has emerged regarding the exact causes of the illness.
Medical teams from premier institutions, including the All India Institute of Medical Sciences (AIIMS) and the National Institute of Mental Health and Neurosciences (NIMHANS), have conducted studies in Bihar over the years. Yet, a comprehensive and universally accepted conclusion remains elusive.
As a result, authorities continue to rely on theories that have been debated for decades, including the role of Culex mosquitoes and toxins associated with litchi consumption. Critics argue that instead of pursuing long-term research and policy interventions, the system largely focuses on seasonal preparedness measures during the peak months when cases are reported.
Experts Call for Comprehensive Research
Dr. Namrata Kumari, a microbiology specialist at Indira Gandhi Institute of Medical Sciences (IGIMS), said no final conclusion has yet been reached regarding the causes of encephalitis.
According to her, conditions ranging from Japanese Encephalitis to Chamki fever may have different underlying causes and symptoms, highlighting the need for extensive and large-scale research in the state.
She added that improving nutrition levels among children in rural areas and ensuring better sanitation could significantly help in controlling the disease. At the same time, she acknowledged that increased vigilance and intervention by the administration have contributed to reducing fatalities in recent years.
High-Level Meeting on Tuesday
In an effort to strengthen preparedness, a high-level meeting of the State Task Force on encephalitis has been convened on Tuesday under the chairmanship of Chief Secretary Pratyaya Amrit.
The meeting will be attended by district magistrates from 12 districts and secretaries from nine government departments. Officials are expected to review and approve an action plan aimed at preventing encephalitis-related deaths during the summer season.
However, questions remain over how effective such action plans can be in the absence of a clear understanding of the disease’s root causes. Health experts have reiterated the need for sustained scientific research and long-term public health measures to address the recurring challenge posed by encephalitis in Bihar.
