## Hantavirus in India: Summary
India is not facing an immediate public health threat from Hantavirus, according to Dr. Priya Abraham, Director of the National Institute of Virology (NIV). This assessment follows recent reports of a human case of Hantavirus in Kerala and heightened awareness due to outbreaks in other parts of the world.
The NIV has been monitoring for Hantavirus since 2010 and has identified several strains in rodent populations across India, primarily in states like Maharashtra, Himachal Pradesh, and Kerala. However, these strains are genetically distinct from those causing severe outbreaks in the Americas, particularly the Andes virus. The Indian strains are more closely related to those found in Eurasia, generally associated with milder disease presentations.
The Kerala case involved a patient who recovered fully, and investigations revealed the presence of the Seoul virus, a common strain found globally and often linked to urban environments and rat infestations. This virus typically causes Hemorrhagic Fever with Renal Syndrome (HFRS), a milder form of the disease compared to the Hantavirus Pulmonary Syndrome (HPS) seen in American outbreaks.
Dr. Abraham emphasized that Hantavirus transmission to humans in India is sporadic and typically occurs through contact with rodent excreta – urine, droppings, and saliva. The risk is higher for individuals working in or living near areas with rodent infestations, such as agricultural fields, forests, and poorly maintained buildings.
Currently, there is no specific vaccine or treatment for Hantavirus infection. Management focuses on supportive care, including maintaining hydration and oxygenation. The NIV is continuing surveillance efforts to understand the prevalence and genetic diversity of Hantavirus strains in India and to assess the potential for future outbreaks. Public health officials recommend rodent control measures and practicing good hygiene to minimize the risk of exposure. Awareness among healthcare professionals regarding early detection and management is also crucial.
