Repeated SARS-CoV-2 Positivity: Analysis of 123 Cases

Study aimed to evaluate the clinical significance of repeatedly positive testing after coronavirus disease 2019 (COVID-19) recovery. We assessed the cases according to the length of their polymerase chain reaction (PCR) negative interval between the two episodes.

Detection of SARS-CoV-2 in respiratory samples from cats in the UK associated with human-to-cat transmission

SARS-CoV-2 RNA was detected in an oropharyngeal swab collected from cat 2 that presented with rhinitis and conjunctivitis. High throughput sequencing of the viral genome revealed five single nucleotide polymorphisms (SNPs) These findings indicate that human-to-cat transmission of SARS- coV- 2 occurred during the COVID-19 pandemic in the UK.

SARS-CoV-2 is associated with high viral loads in asymptomatic and recently symptomatic healthcare workers

Healthcare workers are at increased risk of SARS-CoV-2 infection from both patients and other HCW with coronavirus disease 2019 (COVID-19) First 7-9 days of symptoms are associated with enhanced infectivity.

Difficulties in Differentiating Coronaviruses from Subcellular Structures in Human Tissues by Electron Microscopy

Efforts to combat the coronavirus disease (COVID-19) pandemic have placed a renewed focus on the use of transmission electron microscopy. In attempts to attribute pathology to SARS-CoV-2 patients, investigators have inaccurately reported subcellular structures

Coronaviruses in children: A review of potential mechanisms of childhood protection

Epidemiologic reports indicate that the severity of illness increases with age. The reasons behind the relative protection of children and infants are unclear. Whether the rationale is host-related or virus-dependent is important to determine since the latter could change with viral mutations.

Infectious Clones Produce SARS-CoV-2 That Causes Severe Pulmonary Disease in Infected K18-Human ACE2 Mice

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the ongoing coronav virus disease 2019 (COVID-19) pandemic.

Chemodynamic features of nanoparticles: Application to understanding the dynamic life cycle of SARS-CoV-2 in aerosols and aqueous biointerfacial zones

World Health Organisation acknowledges that SARS-CoV-2 may be transmitted by respiratory droplets. In our theoretical treatment, the virion is assimilated to a core-shell nanoparticle.

The Era of the Coronavirus Disease 2019 Pandemic: A Review on Dynamics, Clinical Symptoms and Complications, Diagnosis, and Treatment

Coronavirus disease 2019 (COVID-19) displays a broad spectrum of clinical presentations. Until now, remdesivir is the only medication approved for the treatment of CoV-19. Other methods of treatment include supportive care directed toward treating the symptoms.
