WHO has assessed India’s recent Nipah virus cases as posing a low risk of wider spread, saying there is no evidence of sustained human-to-human transmission and no need for travel or trade restrictions. The World Health Organization (WHO) has reaffirmed that the recent Nipah virus outbreak in India poses a low risk of wider spread, and there is currently no justification for imposing travel or trade restrictions, the agency said Friday. The assessment follows the confirmation of two cases of Nipah virus infection in West Bengal earlier this month. Public health teams continue surveillance and strict infection control, especially in healthcare settings where infections were first detected. At present, no licensed vaccine or approved antiviral treatment exists for Nipah infection; care is supportive and focused on early detection and isolation.
