The global publications in Nipah virus registered an annual average growth rate of 16.23% and its citation impact averaged to 28.05 citations per paper. Among the 62 countries participating in global Nipah virus research, the top 10 more productive countries account together for more than 100% of its global research output and citation share. The individual global publication share of top 10 most productive countries varied widely 4.23% to 45.98% during 1999-2018, with USA accounting for the highest publication share (45.98%), followed by Australia (16.77%), Malaysia (11.09% share), and other 7 countries (from 4.23% to 7.96%) during 1999-2018. Four of top 10 countries scored relative citation index above the world average of 1.28: Malaysia (1.67), Australia (1.47), Bangladesh (1.41) and USA (1.37) during 1999-2018. The international collaborative papers share of top 10 most productive countries in Nipah virus research varied widely from 24.56% (India) to 88.46% (Bangladesh). Medicine, among various broad subjects, contributed the largest publications share of 59.97% to global Nipah virus research, followed by immunology and microbiology (42.51%), biochemistry, genetics and molecular biology (21.25%), agricultural and biological sciences (11.85%), and other 3 sub-fields contribution varying from 4.57% to 6.10% during 1999-2018. Among various organizations and authors contributing to global Nipah virus research, the 15 most productive global organizations and authors together contributed 65.11% and 48.69% global publication share and 99.15% and 89.29% global citation share respectively during 1999-2018. Amongst 1077 journal papers (in 410 journals) in global Nipah virus research, the top 20 most productive journals contributed 40.39% share of total journal publication output during 1999-2018. Seventy nine (79) publications were found to be high cited, as they registered citations from 101-793 during 1999-2018 and they together received 114880 citations, which averaged to 188.359 citations per paper.

The present study examines the performance of global Nipah virus research during 1999-2018, based on publications output indexed in Scopus database
The citation impact of global publications on Nipah virus research in 20 years averaged to 28.05 citations per publication (CPP) during 1999-2018; its ten-yearly impact averaged to 46.83 CPP for the period 1999-2008, which sharply declined to 16.15 CPP in the succeeding ten-years 2009-2018 (Table 1)
Summary
Nipah virus (NIPV) was first isolated from cerebrospinal fluid (CSF) specimens collected from encephalitic patients in Malaysia in 1999. Nipah virus was first identified as a zoonotic pathogen after an outbreak involving severe respiratory illness in pigs and encephalitic disease in humans in Malaysia and Singapore in 1998 and 1999. A genetically distinct NiV independently emerged in India as well as in Bangladesh, where human NiV outbreak events have been reported nearly every year since. A putative NiV caused an outbreak of disease in horses and people in the Philippines in 2014. There is no reported evidence of NiV outbreaks in humans emerging in any other country than Malaysia, Singapore, Bangladesh, India and Philippines. Subsequent outbreaks in India and Bangladesh have occurred with high case fatality.[4]
