Pubmed is an excellent biomedical database for this topic. You could start with a search which includes terms for the virus (COVID-19 OR 2019 -nCoV) combined with your aspect of interest.
PubMed automates some of the search, so truncation for alternative endings to terms is not required.
To explore different aspects of the disease, we have prepared some set searches for you below in PubMed. You can get current research results just by clicking on the "Run this search in PubMed" link in each section. You can then edit the search further in the search box or using the PubMed filters (for example, English language).
The basic search for Covid-19 diagnosis looks like this:
(COVID-19 OR 2019-nCoV) AND diagnosis
The basic search for treatment and Covid-19 looks like this:
(COVID-19 OR 2019-nCoV) AND (therapy OR intervention OR treatment)
The basic search for infection and Covid-19 looks like this:
(COVID-19 OR 2019-nCoV) AND (infection OR transmission)
The basic search for prevention and Covid-19 looks like this:
(COVID-19 OR 2019-nCoV) AND prevention
There are many reviews and studies that have already been published in this fast moving area. Reviews are great for a quick overview. Editorials and opinion pieces written by experts can also be useful to get a broad perspective of what's happening in Covid-19 research space.
At this emerging stage of the disease, case studies and case series are likely to be more common than other types of studies.
Many of these articles are e-pub ahead of print, meaning that they may not have their full citation information available yet.
Look for articles published in reputable journals. Pubmed has an editorial process which means that results in this database are usually reputable, but you'll still need to assess them for quality.
Accessing Pubmed via Deakin will provide 'Find it at Deakin' links, leading you to full text where Deakin has access. Pubmed also provides access to articles where they are made available open access.
During this health crisis, many publishers have also made articles on Covid-19 available open access where they would otherwise have been subscription access.
Whether it's a twitter post or an email from a colleague, you may come across Covid-19 article links that still require subscription access. You can use this Library bookmarklet tool to quickly check if you have access to the journal and get the information you need quickly.
