Background: The connection between initial viral cycle threshold (Ct) values of the SARS-CoV-2 with symptoms and hospital course is not clearly studied.
Methods: This is a retrospective study of hospitalized COVID-19 patients from Jun 1st 2020 to March 30th, 2021 examining the relationship between initial viral cycle threshold (Ct) values of SARS-CoV-2 as obtained from nasopharyngeal samples. The clinical presentations and outcomes were analyzed in relation to the initial Ct values.
Results: The study included 202 hospitalized COVID-19 patients with a mean age (± SD) of 54.75 (± 15.93) and 123 (60.9%) males and 79 (39.1%) females. Of all the patients, the most frequent comorbidity was diabetes mellitus (95; 47%) and the most frequent symptoms were fever (148; 73.3%) and cough (141; 69.8%). There was no significant difference in relation to underlying conditions, clinical presentation, radiographic and laboratory data among those with low, medium and high Ct values. The mean Ct values showed no statistical change over the 10-month study period.
Conclusions: Initial SARS-CoV-2 Ct values did not show any association with clinical symptoms and did not predict the need for mechanical intubation or death.

A 58-year-old male, with a history of human immunodeficiency virus (HIV) and stage 4 left frontotemporal squamous cell carcinoma (SCC), presented with new-onset neck pain. He was diagnosed with HIV five years prior. The patient had a cluster of differentiation 4 (CD4) count of 53 cells/mm³ and a high viral load, later suppressed with bictegravir, emtricitabine, and tenofovir alafenamide (Biktarvy).

Hemophagocytic lymphohistiocytosis (HLH), is a fatal systemic hyperinflammatory syndrome. HLH may be due to immunosuppression, infections, cancer, or autoimmune diseases with fever and cytopenia. HLH which occurs in adult-onset Stills disease (AOSD) is called secondary HLH, also known as macrophage activation syndrome (MAS).

Background: The UK's National Health Service Test and Trace (NHSTT) program aimed to provide the most effective and accessible SARS-CoV-2 testing approach possible. Early user feedback indicated that there were accessibility issues associated with throat swabbing. We report the results of service evaluations performed by NHSTT to assess the effectiveness and user acceptance of swabbing approaches, as well as qualitative findings of user experiences from research reports, surveys, and incident reports.

The recent outbreak of Marburg virus (MARV) in Rwanda underscores the need for effective countermeasures against this highly fatal pathogen, with case fatality rates reaching 90%. Currently, no vaccines or approved treatments exist for MARV infection, distinguishing it from related viruses like Ebola. Our research demonstrates that the oral drug obeldesivir (ODV), a nucleoside analog prodrug, shows promising antiviral activity against filoviruses in vitro and offers significant protection in animal models.

Dengue virus (DENV) poses a considerable threat to public health on a global scale, since about two-thirds of the world's population is currently at risk of contracting this arbovirus. Being transmitted by mosquitoes, this virus is associated with a range of illnesses and a small percentage of infected individuals might suffer from severe vascular leakage. This leakage leads to hypovolemic shock syndrome, generally known as dengue shock syndrome, organ failure, and bleeding complications.
