  1. Negative antigen RDT and RT-PCR results do not rule out COVID-19 if clinical suspicion is strong

    • The Lancet Infectious Diseases

    • We read with interest the Article by Yap Boum and colleagues,1 which brought significant insight into the importance of rapid diagnostic tests for SARS-CoV-2. Boum and colleagues provided useful information about the patterns of patient presentation. However, some important considerations lead us to suggest an improvement to the algorithm they describe in figure 2A.1 Our feeling is that the clinical context for the suspicion of COVID-19 warrants consideration.

  2. Research in brief

    • The Lancet Infectious Diseases

    • Scientists used human white blood cell membranes to carry two drugs, an antibiotic and an anti-inflammatory, directly to infected lungs in mice. The nano-sized drug delivery method shows a potential new strategy for treating infectious diseases, including COVID-19. The researchers developed a method to essentially peel the membrane from neutrophils, the most common type of white blood cells that lead the body's immune system response.
