Background:
COVID19 is the novel respiratory illness caused by SARS-CoV-2. The presence of other potentially pathogenic microorganisms could worsen the prognosis of these patients.
Aim:
The study aims to describe coinfections in COVID-19 patients and contrast it between standard ward and critical care patients at Hospital Central de la Defensa Gómez Ulla (HCDGU).
Methods:
A retrospective study was carried out of patients with COVID-19 confirmed with RTPCR admitted to the HCDGU from March 5, 2020 to May 7 of 2020.
Findings:
Of a total of 703 patients with COVID-19, 75(10.7%) had other microbiologically confirmed infections: 9% (58/648) in standard ward patients and 31.5%(17/54) in critical care patients. In total 86 samples of the 75 patients presented some microorganism; clinically relevant bacteraemias, 50%, respiratory cultures, 32.6% and pneumococcal positive antigens, 17.4%.
Conclusions:
We found a low frequency of microorganism coinfection in COVID-19 patients, however in critical care these coinfections increased considerably.
