Epidemiological evaluations indicate an increase of acute viral hepatitis B in children. In this study authors performed an analysis of disease prognosis in retrospective trial in children hospitalized in the Pediatric Department of Infectious Diseases from 1983 to 1993 because of acute viral hepatitis B. It was documented that a risk of persistent hepatitis B may be related to the age of patients with acute viral hepatitis B in the past. In 64% of analyzed patients below 1 year old and in 20% over 6 years-persistent hepatitis was diagnosed, especially in male subjects.

Qingwen Zhike prescription (QWZK), a traditional Chinese medicine (TCM) hospital prescription developed in response to the corona virus disease 2019 (COVID-19) pandemic, has demonstrated efficacy in clinical practice. Nevertheless, its specific antiviral components and mechanisms of action remain unclear. This study screened the antiviral compounds against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from Qingwen Zhike prescription and explored the underlying mechanism through chemical composition analysis, serum and lung exposure profiles analysis, high-throughput screening, and transmission electron microscopy (TEM) observation.

Decades of research have defined the function of interferon regulatory factors (IRFs) in the antiviral immune response. Interferon regulatory factor-1 (IRF-1) is the founding member of the IRF family, with recognized antiviral effects across diverse virus infections. While most antiviral activities of IRF-1 were defined in vitro, fewer studies examined the role of IRF-1 during viral infection of an intact host.

Context: Acute myocarditis is a rare but potentially life-threatening condition in infants and children. While immunosuppressive agents have shown limited effectiveness, intravenous immunoglobulin (IVIg) holds promise as a treatment option.
Objective: To study the efficacy and safety of intravenous immunoglobulin (IVIg) in treating acute viral myocarditis in children.

Aging is a major risk factor for poor outcomes following respiratory infections. In animal models, the most severe outcomes of respiratory infections in older hosts have been associated with an increased burden of senescent cells that accumulate over time with age and create a hyperinflammatory response. Although studies using coronavirus animal models have demonstrated that removal of senescent cells with senolytics, a class of drugs that selectively kills senescent cells, resulted in reduced lung damage and increased survival, little is known about the role that senescent cells play in the outcome of influenza A viral (IAV) infections in aged mice.
