Because terminology is evolving so rapidly, and because recently-added citations have not been indexed, some complex strategies are needed for thorough searching in PubMed. The following search statement can be copy-and-pasted into the PubMed search box:
(((((wuhan) AND ((coronavirus) OR "Coronavirus"[Mesh]))) AND ("2019"[Date - Publication] : "2030"[Date - Publication]))) OR ((((2019-nCoV) OR 2019nCoV) OR COVID-19) OR SARS-CoV-2)
Searching Global Index Medicus
The Global Index Medicus (GIM) provides worldwide access to biomedical and public health literature produced by and within low-middle income countries. The main objective is to increase the visibility and usability of this important set of resources. The material is collated and aggregated by WHO Regional Office Libraries on a central search platform allowing retrieval of bibliographical and full text information. Use this search string to search Global Index Medicus:
(wuhan AND (coronavirus OR ( mh:("Coronavirus")))) OR 2019-nCoV OR 2019nCoV OR COVID-19 OR SARS-CoV-2
Due to the rapidly-developing nature of the Coronavirus outbreak, the pace and methods of scientific communication are also changing. While many established journals are speeding up their submission-to-print process, pre-print archives/servers are being used to disseminate and critique research even more rapidly. While it is clearly crucial for research and communication to move as swiftly as possible, pre-publication without rigorous review does entail risks of error and mis-information. As the BioRxiv disclaimer states:
"A reminder: these are preliminary reports that have not been peer-reviewed. They should not be regarded as conclusive, guide clinical practice/health-related behavior, or be reported in news media as established information."
