Chandipura Virus: Causes, Symptoms & Prevention Tips

The Chandipura virus (Chandipura vesiculovirus) is a rare pathogen that belongs to the Rhabdoviridae family. Discovered in 1965 in Chandipura, a village in Maharashtra, India, this virus primarily affects children, causing severe and sometimes fatal encephalitic illness. 

This Chandipura virus recently resurfaced and raised a significant public health concern in India, especially with the outbreak in Gujarat.

This infection causes severe illnesses and fatalities among children. The virus is transmitted by the sting of vector-infected sandflies, predominantly impacting children aged 9 months to 14 years in rural areas. Health authorities, including Gujarat’s Health Minister Rushikesh Patel, emphasize caution while addressing public concerns. 

Despite being known for over five decades, the Chandipura virus still demands attention due to its rapid fatality rate. 

This blog provides information about the virus, its causes, symptoms, and the necessity for vigilant public health measures.

What is the Chandipura Virus?

The Chandipura virus (Chandipura vesiculovirus) is an RNA virus from the Rhabdoviridae family, first identified in 1965 in Chandipura village, Maharashtra, India. 

It mostly affects children and causes encephalitic illness with high mortality rates. 

The virus is transmitted by sandflies, particularly the Phlebotomus species, and occasionally by mosquitoes like Aedes aegypti. It was initially isolated from the blood of two children during a dengue fever outbreak. 

Chandipura virus outbreaks are common in rural areas where these vectors thrive. There were numerous deaths in 2003 as a result of outbreaks in central India, including Andhra Pradesh and Maharashtra.

Chandipura Virus Symptoms

The Chandipura virus, affecting primarily children under 15, presents a range of symptoms that can escalate rapidly, making early diagnosis and treatment crucial.

• Fever: One of the earliest signs of Chandipura virus infection is a sudden onset of high fever. This intense and persistent fever can lead to discomfort and further complications if not managed properly.
• Headache: Severe headaches often accompany the fever, creating significant discomfort and contributing to the overall severity of the infection.
• Vomiting: Nausea and vomiting are common symptoms, which can be severe and persistent, leading to dehydration and further health issues.
• Neurological Symptoms: In severe cases, the infection can lead to significant neurological symptoms, including confusion, altered consciousness, and seizures. These symptoms indicate the virus’s impact on the central nervous system and may progress to conditions like encephalitis.
• Convulsions and Seizures: Seizures or convulsions may occur, particularly in severe cases. These are indicative of the virus’s severe impact on brain function.
• Gastrointestinal Issues: Diarrhea and abdominal pain may also contribute to the overall discomfort and complicate the clinical picture.
• Meningeal Irritation: Symptoms such as headaches, a stiff neck, sensitivity to light, and seizures can signal meningeal irritation, a serious complication of the infection.
• Muscle and Joint Pain: Muscle aches and joint pain are frequently reported and can add to the overall discomfort during the illness.

As the virus’s infection progresses, severe complications like encephalitis and respiratory distress occur. Rapid deterioration is common and death can often occur within 48 hours of hospital admission. 

How does this infection spread?

The Chandipura virus is primarily transmitted through the bite of infected sandflies, particularly those from the Phlebotomus genus. These sandflies are most abundant during the early monsoon season, contributing to the virus's spread.

Even though the precise transmission mechanisms have yet to be fully understood, sandflies are considered the primary vectors to cause this infection. 

Certain environmental conditions that favor sandfly breeding can exacerbate outbreaks.

The virus predominantly affects children aged 2 to 16 years and is associated with severe neurological complications.

Preventive Tips for Chandipura Virus Infection

Preventing Chandipura virus infection is essential, due to the virus's rapid and severe impact.

1. Avoid Sandfly Bites  

• Use insect repellents and wear protective clothing to minimize skin exposure.
• Avoid outdoor activities during peak sandfly activity times, typically during the early monsoon season.

2.Maintain Hygiene

• Keep your surroundings clean to reduce sandfly breeding sites.
• Wash hands regularly with soap and water, especially after outdoor activities.

3.Public Health Measures

• Utilize insecticide spraying in areas where sandflies breed.
• Use bed nets, particularly in rural areas where sandflies are common.

Implementing these steps can help reduce the risk of infection and manage the spread of the Chandipura virus effectively.

Chandipura Virus Infection Treatment

There is no specific treatment or vaccine for Chandipura virus infection. The focus is on supportive care to alleviate symptoms and prevent complications. 

• Hospitalization: Severe cases, especially in children, often require hospitalization for intensive care.
• Hydration: Maintaining proper fluid balance is crucial, particularly if severe vomiting is present.
• Fever Management: Antipyretics are used to reduce high fever and provide comfort.
• Seizure Control: Anticonvulsants may be administered to manage seizures effectively.
• Intensive Care: For severe neurological symptoms, intensive care may be necessary to address respiratory and neurological issues.

There is an increasing concern regarding the Chandipura virus in Gujarat, Maharashtra, and surrounding areas currently. While research continues to develop specific treatments and vaccines, current strategies focus on vector control and raising awareness.
