Abstract
OBJECTIVE: This study aimed to estimate research productivity and general characteristics of research in different regions of the world in the field of human metapneumovirus (hMPV). MATERIALS AND METHODS: We used the Web of Science (WoS) electronic database to retrieve articles on "human metapneumovirus," published up to March 31, 2023. Parameters such as research productivity, the total number of publications, average citation counts of all articles, research productivity by top publishing countries and affiliated organizations, links between countries/organizations, and top keywords were assessed. RESULTS: We found 826 articles in the WoS database. The first article on hMPV was published in 2002, and 2008 was the year that the most articles on hMPV were published, with 70 articles. The articles were cited 26,797 times (14,498 times without self-citations) and 32.25 times on average per article. Hirsch (H)-index was 80. The year 2008 also had the highest number of citations, with more than 1800. The United States was the most productive country, producing 295 documents (35.714%), one-third of all publications in this field worldwide. Canada (6.5%) and Japan (6.5%) followed the United States regarding total hMPV publications worldwide. The leading funding agencies for hMPV research were from the United States, Europe, China, and Japan. CONCLUSION: Our findings imply that developed countries should assist developing countries in enhancing their research infrastructures.
