The COVID-19 resource centre, hosted by Elsevier, provides free information in English and Mandarin on the novel coronavirus. Elsevier grants permission to make all its COVID-19-related research available in PubMed Central and other public repositories, with unrestricted access for research reuse and analysis. A systematic review and meta-analysis by Louise Lansbury, Benjamin Lim, Vadsala Baskaran, and Wei Shen Lim evaluates the burden of co-infections in patients with COVID-19. The study included 30 studies with 3834 patients, finding that 7% of hospitalized COVID-19 patients had a bacterial co-infection (95% CI 3–12%), with Mycoplasma pneumoniae, Pseudomonas aeruginosa, and Haemophilus influenzae being the most common bacteria. The proportion of patients with viral co-infections was 3% (95% CI 1–6%), with Respiratory Syncytial Virus and influenza A being the most common. The findings suggest that the use of antibiotics in the management of confirmed COVID-19 infection is not necessary, as the proportion of co-infections is lower than in previous influenza pandemics.The COVID-19 resource centre, hosted by Elsevier, provides free information in English and Mandarin on the novel coronavirus.
