Full Form of HEV
What is HEV?
Hepatitis E Virus (HEV) is a single-stranded RNA virus that causes hepatitis E, an acute inflammatory disease of the liver. It is primarily transmitted through the fecal-oral route, often via contaminated drinking water, making it a significant public health concern in India where waterborne outbreaks are common. HEV is endemic in many parts of the country, especially during monsoon seasons when sanitation infrastructure is overwhelmed. The infection typically presents with jaundice, fatigue, abdominal pain, and nausea, and is usually self-limiting in healthy individuals. However, it poses a severe risk to pregnant women, where mortality rates can reach up to 25% in the third trimester. HEV is diagnosed through serological tests (anti-HEV IgM) and PCR detection of viral RNA. In Indian medical curricula, HEV is a key topic in microbiology and preventive medicine, often featured in competitive exams like NEET PG and AIIMS. The virus has four genotypes, with genotypes 1 and 2 circulating in developing countries like India. Unlike hepatitis B or C, HEV does not lead to chronic infection in immunocompetent persons. Vaccination for HEV is available in China but not yet widely used in India, making hygiene and safe water practices the primary prevention measures.
