Does Pulmonary Aspergillosis Complicate Coronavirus Disease 2019?

OBJECTIVES: Aspergillus coinfection in coronavirus disease 2019 patients has rarely been described but may be occurring among coronavirus disease 2019 patients admitted to ICUs. Previous reports of viral coinfections with Aspergillus, including influenza-associated pulmonary aspergillosis, suggest that coronavirus disease 2019-associated aspergillosis is plausible. This report aims to summarize what is known about coronavirus disease 2019 complicated by Aspergillus, introduces coronavirus disease 2019-associated pulmonary aspergillosis as a possible clinical entity, and describes reasons clinical suspicion of Aspergillus is warranted in the critical care setting. DATA SOURCES: We summarize the available evidence suggesting the existence of Aspergillus coinfection among severe coronavirus disease 2019 patients. This includes published coronavirus disease 2019 patient case series, a case description, and a review of potential biologic mechanisms. STUDY SELECTION: Reports of coronavirus disease 2019 patient attributes were selected if they included clinical, microbiologic, or radiologic signs of invasive fungal infection. DATA EXTRACTION: Data included in summary tables were identified through a literature search for coronavirus disease 2019-associated pulmonary aspergillosis. DATA SYNTHESIS: We present descriptive data extracted from coronavirus disease 2019-associated pulmonary aspergillosis case series current at the time of article submission. DISCUSSION: Pulmonary aspergillosis is known to occur among influenza patients requiring intensive care and is associated with increased mortality. If Aspergillus coinfections are occurring among coronavirus disease 2019 patients, early clinical suspicion and testing are needed to understand the epidemiology of these infections and prevent associated mortality. As the coronavirus disease 2019 pandemic unfolds, reports on the existence of this coinfection are needed, and opportunities to contribute cases of Aspergillus coinfection among coronavirus disease 2019 patients to an ongoing registry are described.

Enhanced contact investigations for nine early travel-related cases of SARS-CoV-2 in the United States.

Coronavirus disease 2019 (COVID-19), the respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China and has since become pandemic. In response to the first cases identified in the United States, close contacts of confirmed COVID-19 cases were investigated to enable early identification and isolation of additional cases and to learn more about risk factors for transmission. Close contacts of nine early travel-related cases in the United States were identified and monitored daily for development of symptoms (active monitoring). Selected close contacts (including those with exposures categorized as higher risk) were targeted for collection of additional exposure information and respiratory samples. Respiratory samples were tested for SARS-CoV-2 by real-time reverse transcription polymerase chain reaction at the Centers for Disease Control and Prevention. Four hundred four close contacts were actively monitored in the jurisdictions that managed the travel-related cases. Three hundred thirty-eight of the 404 close contacts provided at least basic exposure information, of whom 159 close contacts had ≥1 set of respiratory samples collected and tested. Across all actively monitored close contacts, two additional symptomatic COVID-19 cases (i.e., secondary cases) were identified; both secondary cases were in spouses of travel-associated case patients. When considering only household members, all of whom had ≥1 respiratory sample tested for SARS-CoV-2, the secondary attack rate (i.e., the number of secondary cases as a proportion of total close contacts) was 13% (95% CI: 4-38%). The results from these contact tracing investigations suggest that household members, especially significant others, of COVID-19 cases are at highest risk of becoming infected. The importance of personal protective equipment for healthcare workers is also underlined. Isolation of persons with COVID-19, in combination with quarantine of exposed close contacts and practice of everyday preventive behaviors, is important to mitigate spread of COVID-19.

Ventilator-associated pneumonia involving Aspergillus flavus in a patient with coronavirus disease 2019 (COVID-19) from Argentina.

Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus SARS-CoV-2, emerged in Wuhan, China, in December 2019 and rapidly spread around the world. Invasive aspergillosis has been reported as a complication of severe influenza pneumonia among intensive care patients. Similarities between COVID-19 and influenza pneumonia, together with limited published case series, suggest that aspergillosis may be an important complication of COVID-19. This report describes a case of ventilator-associated pneumonia involving Aspergillus flavus in a patient with COVID-19 from Buenos Aires, Argentina.
