RT Journal Article SR Electronic T1 Pneumocystis pneumonia, a COVID-19 mimic, reminds us of the importance of HIV testing in COVID-19 JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 590 OP 592 DO 10.7861/clinmed.2020-0565 VO 20 IS 6 A1 Sophie Kelly A1 Laura Waters A1 Muge Cevik A1 Simon Collins A1 Joe Lewis A1 Meng-San Wu A1 Tom J Blanchard A1 Anna M Geretti YR 2020 UL http://www.rcpjournals.org/content/20/6/590.abstract AB While clinical environments are highly focused on COVID-19, reports of missed or delayed treatment for conditions that imitate COVID-19, such as pneumonia caused by the fungus Pneumocystis jirovecii, are emerging. Given the uncertain spectrum of COVID-19 presentations and variable sensitivity of laboratory tests for SARS-CoV-2, there is a risk that, without a high index of suspicion, alternative aetiologies may be overlooked while pursuing a diagnosis of COVID-19. The British HIV Association has been calling for the inclusion of HIV testing in all patients admitted to hospital with suspected COVID-19. In this article we reflect on the importance of including HIV testing to prevent avoidable morbidity and mortality in our patients.
