BACKGROUND: Recent events highlight how emerging and re-emerging pathogens are
actually becoming global challenges for public health. In December 2019, a novel
coronavirus (SARS-CoV-2) has emerged. This has suddenly turned out into a global
health concern which has led to a very high number of papers published in the
scientific literature. Aim of this research is to focus on the bibliometric
aspects in order to give researchers a glimpse on what is published in the first
30-days of a global epidemic outbreak. METHODS: We searched MEDLINE (PubMed)
electronic database in order to find all relevant studies in the first 30-days
from the first publication (which appeared on Pubmed at 14/01/2020), meaning the
period 15/01/2020-13/02/2020. We used the following search string: coronavirus*
OR Pneumonia of Unknown Etiology OR Covid-19 OR nCoV. We placed a language
restriction for English, but no publication status or study design limit was put
in place for our search. RESULTS: From the initial 462 identified articles, 234
articles were found as pertinent and read in extenso in order to classify them.
The vast majority of papers come from China, UK and USA. 66.2% of the papers were
Editorials, comments, letters or other kind of mainly reported data. 10.7% of
papers were secondary literature papers (mainly narrative reviews). The remaining
23.1% were original primary studies. Only 17.5% of the sources used data which
were directly collected on the field. CONCLUSIONS: Almost all of data came from
China. Even if some preferential channels were guaranteed for publishing those
results in the most important journals, it appears that the vast majority of
publication in scientific literature in the first 30-days of an epidemic outbreak
is based more on reported data and comments, and only a small fraction of the
papers have primary data collected in the field. Nevertheless the whole
international literature depends on that type of data sources in the early days
of the epidemic. KEY MESSAGES: This is the first bibliometric research in Pubmed
Database on the first 30 days of publications regarding the novel Coronavirus
(2019-nCoV) outbreak of 2019. The vast majority of publication in the first
30-days of an epidemic outbreak are reported data or comments, and only a small
fraction of the papers has directly collected data.
