Bats are the natural host and vector for a number of emerging zoonotic viruses (e.g. SARS coronavirus, Ebola virus, Middle East Respiratory Syndrome Coronavirus (MERS-CoV)) that have circulated internationally. In South East Asia, Nipah virus is another source of similar infections the natural host of which is the fruit bat. People who have direct contact with infected animals or body fluid of infected people, or have drunk contaminated raw date palm sap could be at risk of infection.

In May 2018, a Nipah virus outbreak was reported in Kozhikode, India. By June 2018, 18 cases have been reported, giving a high mortality rate of 94%. The map shows the distribution of reported Nipah virus outbreaks in South and South East Asian countries. These countries are located within the hashed area, which covers the home range of fruit bats. Since 2001, Nipah virus outbreaks have been reported in India and Bangladesh only. The inset map shows the number of years that the 2 countries had reported Nipah virus outbreaks and their locations.

By now, there is no vaccine against the Nipah virus. Members of the public are advised not directly touch bats or pigs, or drink raw date palm sap, to reduce the risk of infection.

蝙蝠是幾種國際間新興人畜共患病毒 (如嚴重急性呼吸道綜合症冠狀病毒、伊波拉病毒、中東呼吸綜合症病毒) 的天然宿主及傳播媒介。南亞及東南亞地區的尼帕病毒,其天然宿主亦是果蝠。人若接觸已受尼帕病毒感染的動物或病人的體液、飲用一些受污染的椰棗原汁就會有感染機會。

2018年5月,尼帕病毒在印度的科澤科德縣爆發。到2018年6月為止,已經有18宗報告感染個案及高達94%的死亡率。地圖中圓點顯示曾經爆發過尼帕病毒的國家。地圖的間條部分是果蝠活動的範圍,而曾經爆發過尼帕病毒的國家也是在間條範圍內。2001年開始,該範圍內只有印度和孟加拉報告過尼帕病毒爆發。插圖顯示在這兩個國家曾經報告過尼帕病毒爆發的地點及總年數。

現時暫時未有預防尼帕病毒的疫苗。建議市民不要隨便接觸蝙蝠、飲用椰棗原汁、以及觸摸豬隻以降低感染尼帕病毒的風險。
