Hantavirus is a group of viruses that primarily spread from rodents to humans, causing serious illness when contaminated particles are inhaled or come into contact with infected rodent waste. The virus is named after the Hantan River in South Korea, where it was first isolated from field mice. Dr. Priyanka Prakash, an Associate Consultant in Infectious Diseases, emphasizes the importance of awareness and early recognition due to the virus's high fatality rate, particularly with the Andes strain, which can transmit between humans. Symptoms typically develop in two phases, starting with mild viral symptoms and potentially leading to severe respiratory complications, including pneumonia and acute respiratory distress syndrome (ARDS). Currently, there are no approved vaccines or specific antiviral treatments, making prevention crucial. This includes avoiding contact with rodents, sealing entry points in homes, and using protective gear when cleaning contaminated areas. Despite its rarity, timely attention and preventive measures are essential to mitigate severe outcomes and prevent further spread.
