Database searching

This section provides details of COVID-19-related information sources, including guidance on how to search, databases, preprint servers, grey literature, search terms, and searching strategies for specific sources. In addition, you will also find links to live literature searches, and reference management software.

Guides on how to search

The World Health Organization has produced this reference book about methods to guide Health-Emergency and Disaster Risk Management, and chapter 6.2 is specifically about how to search for reports of existing research. Health Emergency and Disaster Risk Management (Health-EDRM) has recently emerged as a critical field for research, policy, and practice as a result of the growing recognition of health as a core dimension in disaster risk management.

A roadmap for searching literature in PubMed is a LibGuide, produced by Vrije Universiteit Amsterdam, which teaches you how to build and conduct a systematic search in PubMed. The following topics are covered: research question formulation, collecting MeSH and free-text terms, truncation and phrase searching, combining search terms, use of search filters, evaluation search strategies, and managing references.


Guide to Covid-19 Rapid Review CollectionsThis resource has been created by the UK Health Security Agency Knowledge and Library services team. It is a reference guide to organisations who produce rapid reviews or evidence summaries on COVID-19 topics. Its purpose is to enable the quick discovery of evidence to answer research questions. It is made available so that those who intend to undertake reviews can check the evidence base before doing so, thus avoiding unnecessary duplication of effort. Please note that it is not an exhaustive list.
PROSPEROThis is an international prospective register of systematic reviews, rapid reviews, and umbrella reviews. They are fast-tracking registration of protocols related to COVID-19. Before starting a systematic review, check this resource, and if one is already being undertaken, please do not duplicate without good reason. Switch to another topic to avoid research waste and contribute more effectively to tackling the pandemic.
COVID-ENDThis is an inventory of ‘best evidence syntheses’ for all types of decisions being faced by those who are part of the COVID-19 pandemic response. The evidence is divided into four parts: public-health measures (e.g. masks and tests), clinical management of COVID-19 (e.g. prescription drugs) and pandemic-related conditions (e.g. mental health and addictions issues), health-system arrangements (e.g., scaling capacity up or down and virtual-care alternatives to in-person care), and economic and social responses (e.g., classroom and public-transit changes). Before starting a systematic review, check this resource, and if one is already being undertaken, please do not duplicate without good reason. Switch to another topic to avoid research waste and contribute more effectively to tackling the pandemic.
L·OVE platformThis is a Living OVerview of COVID-19-related Evidence. The word ‘living’ describes a system that is updated as soon as new evidence becomes available. It maps and organises all the best evidence on COVID-19. This resource is part of the Epistemonikos multilingual database of health evidence, the largest source of systematic reviews relevant for health-decision making, and a large source of other types of scientific evidence.
WHO Global Research Database on COVID-19This database represents a comprehensive multilingual source of current literature on the topic. It is updated daily from searches of bibliographic databases, hand searching, and the addition of other expert-referred scientific articles.
LitCovidProduced by the National Library of Medicine, this resource provides a central access to 72516 (and growing) relevant articles about COVID-19 in PubMed. The articles are updated daily and are organised under 8 headings (general, mechanism, transmission, diagnosis, treatment, prevention, case report, and forecasting). They are further categorised by different research topics and geographic locations for improved access.
Children and COVID-19 Research LibraryCurated by UNICEF, this is a curated collection of research about COVID-19 and children.
CoronaCentral This resource collates published papers and preprints for SARS-CoV-2, MERS-CoV and SARS-CoV, and organises them by browsable themes (epidemiology, clinical, biology, treatment, psychology, and policy). You can also search by keyword.

Google and Google Scholar are two popular information sources, but there are also some bibliographic databases, such as PubMed, Medline, Embase, Global Health, and Global Index Medicus, which support more advanced searching and provide access to relevant biomedical journals. More information about accessing databases is available here.

Preprint sources

The COVID-19 Portfolio has been created by the National Institutes of Health. It is a comprehensive, expert-curated source for publications and preprints related to either COVID-19 or the novel coronavirus SARS-CoV-2. It includes articles from PubMed and preprints from arXiv, bioRxiv, ChemRxiv, medRxiv, Research Square, and SSRN, and is updated daily.  

Grey literature searching

The MedNar database is a US resource which searches journal articles, medical societies, and other government resources.

Search terms

To search these resources, it is important to use the right terminology. This is not an exhaustive list of COVID-19 search terms, as the terminology is changing regularly, but it is a starting point, and a combination of these terms can be used to search the information sources described above:

  • coronavirus*
  • coronovirus*
  • "Coronavirus"
  • "Coronavirus Infections"
  • "Wuhan coronavirus"
  • Wuhan
  • "2019-nCoV"
  • COVID-19
  • CORVID-19
  • CONVID-19
  • WN-CoV
  • HCoV-19
  • "novel coronavirus"
  • "new coronavirus"
  • CoV
  • 2019 novel
  • new coronavirus
  • ncov
  • SARS-CoV-2
  • SARSCov19
  • ncov*wuhan
  • (outbreak* OR "respiratory illness" OR "respiratory disease" OR respiratory symptom* OR seafood market OR food market OR wildlife) and (Wuhan OR China OR Chinese)

Medical Subject Headings (MeSH)

The U.S. National Library of Medicine produces the Medical Subject Headings (MeSH) thesaurus, a controlled and hierarchically-organized vocabulary, used for indexing, cataloguing, and searching of biomedical and health-related information. Here are some multi-language versions of MeSH:

Search strategies

A number of organisations have developed search strategies to make it easier for people to find the evidence on freely-available information sources:

United Kingdom Health Security Agency

  • UKHSA Knowledge and Library Services Team has developed (and updated on 08/03/2021) a search strategy specifically for PubMed, an openly accessible database of biomedical literature, produced by the U.S. National Library or Medicine:
(coronavirus*[Title] OR coronovirus*[Title] OR coronoravirus*[Title] OR coronaravirus*[Title] OR corono-virus*[Title] OR corona-virus*[Title] OR "Coronavirus"[Mesh] OR "Coronavirus Infections"[Mesh] OR "COVID-19"[Mesh] OR "SARS-CoV-2"[Mesh] OR "COVID-19 Serological Testing"[Mesh] OR "COVID-19 Nucleic Acid Testing"[Mesh] OR "COVID-19 Testing"[Mesh] OR "COVID-19 Vaccines"[Mesh] OR "Wuhan coronavirus" [Supplementary Concept] OR COVID-19[Title] OR CORVID-19[Title] OR "2019nCoV"[Title] OR "2019-nCoV"[Title] OR WN-CoV[Title] OR nCoV[Title] OR "SARS-CoV-2"[Title] OR HCoV-19[Title] OR "novel coronavirus"[Title])

If you are searching for evidence from the start of the outbreak then you should combine the above search (using OR) with the following terms:

OR ((wuhan[Title/Abstract]) AND (pneumonia[Title/Abstract] OR outbreak*[Title/Abstract] OR "respiratory illness"[Title/Abstract]))) OR "Wuhan novel coronavirus"[Title/Abstract]) OR "Wuhan coronavirus"[Title/Abstract]) 

If you want to compare the current outbreak with previous similar breaks, you should add search terms for Middle East Respiratory Syndrome (MERS, MERSCoV, MERS-CoV) and Severe Acute Respiratory Syndrome (SARS, SARS-CoV-1, SARSCoV-1, SARSCoV1, SARS-CoV1, SARSCoV, SARS-CoV, SARS1, SARS-1, SARScoronavirus1, SARS-coronavirus-1, SARScoronavirus 1, SARS coronavirus1, SARScoronovirus1, SARS-coronovirus-1, SARScoronovirus 1, SARS coronovirus1).
