The Emerging Challenge of Crimean-Congo Hemorrhagic Fever in India: Why Livestock Handlers Are at Risk

Crimean-Congo Hemorrhagic Fever (CCHF) is a viral disease transmitted through tick bites or contact with infected animal blood. While it has been sporadically reported in India, recent cases highlight its potential to become a significant public health threat, especially among livestock handlers and farmers.

What Is CCHF? CCHF is caused by the Nairovirus, which belongs to the Bunyaviridae family. The virus is primarily transmitted by Hyalomma ticks, commonly found on livestock such as cattle, goats, and sheep. Humans can contract the virus through:

• Tick bites
• Direct contact with blood or tissues of infected animals
• Person-to-person transmission via blood or bodily fluids

Why Livestock Handlers Are Vulnerable Livestock handlers, including farmers, butchers, and veterinarians, are at heightened risk due to frequent exposure to ticks and animal blood. Key risk factors include:

• Working in tick-infested areas
• Handling animals without protective gear
• Lack of awareness about the disease and its transmission

Symptoms and Diagnosis The disease progresses in stages:

1. Initial Phase: Fever, headache, muscle pain, and dizziness.
2. Hemorrhagic Phase: Bruising, nosebleeds, and bleeding from other sites.
3. Severe Phase: Organ failure and shock.

Diagnosis relies on:

• PCR testing for viral RNA
• Serological tests to detect antibodies

Prevention and Management Prevention focuses on reducing exposure to ticks and infected animals:

• Wear protective clothing (gloves, boots, long sleeves) when handling livestock.
• Use insect repellents to prevent tick bites.
• Avoid close contact with animals showing signs of illness.
