Given the current situation Trip has been adding as many high-quality documents on Covid-19 that we can find. This means at least daily uploads of new material. The best search is not “covid-19” (which currently returns 35 results), so we recommend searching for covid-19 or “novel coronavirus” (which returns 143)!
Trip is also involved in the Oxford COVID-19 Evidence Service, helping support a significant number of rapid reviews.
If you see any useful resources then please let us know.
