WHO: Risk of Nipah Virus Spread Globally Remains Low

The World Health Organization (WHO) announced that the risk of the Nipah virus spreading, following cases reported in India and Bangladesh, remains low both regionally and globally. The virus causes symptoms such as high fever, vomiting, and respiratory infection, and in severe cases can lead to convulsions, encephalitis, and coma. There is currently no vaccine available for the virus, which is typically transmitted from animals or contaminated food, with a mortality rate ranging from 40% to 75%. The WHO noted that the two recent cases in India and Bangladesh are not linked, despite appearing in areas near the border between the two countries, where fruit bats, which are the natural carriers of the virus, are present. Following the monitoring of over 230 contacts, no additional cases have been identified. The Nipah virus first emerged in 1998 in Malaysia, with cases among pig farmers, while an outbreak occurred in Kerala, India, in 2018, resulting in 17 deaths. The WHO continues to monitor the situation and coordinate efforts to combat the virus. WHO Director-General Tedros Adhanom Ghebreyesus stated that the organization assesses the risk of Nipah virus spread as low, but emphasizes the importance of vigilance and early diagnosis and management of cases.
