Bacterial Infection Less Prevalent in COVID 19 Pneumonia than Non-COVID 19 Pneumonia
Many patients with Coronavirus disease-2019 (Covid-19) present radiological evidence of pneumonia. Historically, patients hospitalized for influenza and influenza-like viral syndromes be more susceptible to bacterial super-infection. However, in a study, researchers have found that non-Covid-19 patients with pneumonia were more likely to have a bacterial infection than Covid-19 patients. The study findings were published in The American Journal of Emergency Medicine on September 28, 2021.
Over the last 2 decades, the world has experienced at least six major viral epidemics, including SARS-CoV, MERS, H1N1, Ebola, Zika, and the current SARS-CoV-2. Bacterial super-infections during these viral illnesses have been associated with poor outcomes. However, data on the prevalence of bacterial superinfection in Covid-19 positive patients is not well established. Because it is difficult to determine the co-existence of bacterial pneumonia, many of these patients are initially treated with antibiotics. Therefore, Dr Adam J. Singer and his team conducted a study and compared the rates of bacterial infections and mortality in Covid-19 patients with pulmonary infiltrates versus patients diagnosed with 'pneumonia' the year previously.
