What is Chandipura Virus?
Chandipura virus (CHPV) is a rare, neurotropic pathogen belonging to the Rhabdoviridae family. It is a major cause of Acute Encephalitis Syndrome (AES) in children, particularly in rural and agricultural regions of India. The virus is transmitted through the bite of infected female phlebotomine sandflies (Phlebotomus and Sergentomyia species).
First isolated in 1965 from a patient in Chandipura village, Maharashtra, CHPV has since been associated with sporadic outbreaks and high mortality rates (55–70%) when neurological complications develop rapidly.
Transmission Vectors and Incubation
CHPV is not contagious between humans. The primary vector is the female sandfly, which breeds in damp soil, wall cracks, and decaying organic matter. The incubation period typically ranges from 1 to 7 days, after which symptoms appear abruptly.
Key Point: Unlike mosquito-borne encephalitis viruses, CHPV has no approved vaccine, making vector control and early diagnosis critical.
Clinical Presentation and Symptom Timeline
Symptoms progress rapidly, often within 24–48 hours. The following table outlines the typical timeline:
| Time from Onset | Symptoms |
|---|---|
| 0–12 hours | Sudden high-grade fever, severe headache, vomiting, loss of appetite |
| 12–24 hours | Altered sensorium, lethargy, behavioral changes, confusion |
| 24–48 hours | New-onset seizures, coma, signs of raised intracranial pressure |
Diagnostic Modalities
Early laboratory confirmation is essential. DNA Labs India offers the following tests:
- RT-PCR (Real-Time Polymerase Chain Reaction): Detects viral RNA in blood or CSF during the acute phase (first 3–5 days). This is the gold standard for early diagnosis.
- IgM Capture ELISA: Detects antibodies in serum or CSF from day 5 onward; useful for retrospective confirmation.
- Cerebrospinal Fluid Analysis: Shows pleocytosis and elevated proteins, supporting the diagnosis of encephalitis.
