Rabies in India: A Growing Concern

Introduction

Rabies is a vaccine-preventable viral disease that attacks the central nervous system and is almost invariably fatal once symptoms appear. In India, the disease is a significant public health concern, with estimates suggesting that it accounts for 35% of rabies deaths globally and 59.9% of rabies deaths in Asia.

However, the country's rabies mortality data is inconsistent, posing a challenge to eliminating dog-mediated human rabies by 2030. According to the Union Health Ministry, there were 21 deaths by rabies in 2022, 50 in 2023, and 54 in 2024. In contrast, a community-based study led by researchers from the Indian Council of Medical Research-National Institute of Epidemiology (ICMR-NIE) estimated that 5,726 people die of rabies in India every year.

Rabies Surveillance in India

The Registrar General of India's Medical Certification of Cause of Death (MCCD) system recorded 66 medically certified rabies deaths in 2022, and 271 in 2023. However, the MCCD system only covers medically certified deaths and does not capture all registered deaths.

The Integrated Disease Surveillance Programme-Integrated Health Information Platform (IDSP-IHIP) system reported 21 deaths by rabies in 2022, 50 in 2023, and 54 in 2024. However, the IDSP-IHIP is a disease surveillance system, and its data is not directly comparable to the MCCD system.

Challenges in Rabies Surveillance

The difference between the two datasets is substantial, with the 54 deaths reported through government surveillance in 2024 being less than 1% of the study's estimated annual toll of 5,726. This highlights a large gap between reported surveillance deaths and estimated mortality.

A senior Health Ministry official noted that the two figures are generated through different methods and should not be treated as directly equivalent. The lack of consolidated data is a challenge in rabies eradication, with cases and deaths often occurring in areas where they are not measurable.

Efforts to Eliminate Rabies

The National Centre for Disease Control is working to make human rabies a notifiable disease across India, and all States have been asked to notify the disease under the relevant State legislation.

The Health Ministry has acknowledged the surveillance challenge, with deaths occurring outside the formal health system posing an additional difficulty in capturing the full burden of disease.

A study published in The Lancet Infectious Diseases found important gaps in post-exposure care, with about one in five dog-bite victims not receiving the anti-rabies vaccine, and only 66.2% receiving at least three doses.

Rabies Prevention and Control

Rabies is entirely preventable through timely vaccination of dogs and prompt post-exposure care. The World Health Organization (WHO) estimates that domestic dogs are responsible for up to 99% of human rabies transmission.

The ICMR-funded study states that although there has been a substantial decline in human rabies deaths over the past two decades, India needs to fast-track its actions to eliminate dog-mediated human rabies by 2030 by adopting a focused 'One Health' approach.

• Integrating human and animal surveillance
• Ensuring timely administration of the full course of post-exposure prophylaxis
• Accelerating dog vaccination across the country

Nirmal Kumar Ganguly, medical scientist, public health expert, and former ICMR chief, noted that vaccination of stray dogs, stringent post-exposure vaccination for humans, and disruption of the rabies chain is essential to curb the problem.

Conclusion

In conclusion, India's rabies mortality data is inconsistent, posing a challenge to eliminating dog-mediated human rabies by 2030. The country needs to fast-track its actions to eliminate the disease by adopting a focused 'One Health' approach, integrating human and animal surveillance, ensuring timely administration of the full course of post-exposure prophylaxis, and accelerating dog vaccination across the country.

Implications for Readers in India

As a reader in India, it is essential to be aware of the risks of rabies and take preventive measures. This includes vaccinating pets, avoiding contact with stray animals, and seeking medical attention immediately if bitten or exposed to a potentially rabid animal.

What to Watch Next

The Indian government's efforts to make human rabies a notifiable disease and the implementation of a 'One Health' approach will be crucial in eliminating dog-mediated human rabies by 2030. Readers can expect updates on the progress of these initiatives and the impact on rabies mortality rates in the country.

Expert Perspective

Experts emphasize the need for a multi-faceted approach to eliminate rabies in India. This includes increasing awareness about the disease, improving access to healthcare, and implementing effective surveillance and control measures.

Timeline of Rabies Elimination Efforts

The Indian government has set a target to eliminate dog-mediated human rabies by 2030. The following are key milestones in the efforts to eliminate rabies in India:

• 2022: The Union Health Ministry reports 21 deaths by rabies.
• 2023: The Union Health Ministry reports 50 deaths by rabies.
• 2024: The Union Health Ministry reports 54 deaths by rabies.
• 2025: The Indian government aims to make human rabies a notifiable disease across India.

Background of Rabies in India

Rabies has been a significant public health concern in India for decades. The disease is prevalent in many parts of the country, and the lack of effective surveillance and control measures has hindered efforts to eliminate it.

The World Health Organization (WHO) estimates that India accounts for 35% of rabies deaths globally and 59.9% of rabies deaths in Asia. The WHO also estimates that domestic dogs are responsible for up to 99% of human rabies transmission.
