TL;DR: Quantitative monitoring of viral load in lower respiratory tract samples helps to evaluate disease progression, especially in cases of low viral load.

TL;DR: A convenience sample of patients admitted to Beijing Ditan Hospital, Capital Medical University, with a diagnosis of COVID-19 and paired RT-qPCR testing of pharyngeal swabs with either sputum or feces samples showed positive results for SARS–CoV-2 RNA.

TL;DR: Genomic comparisons reveal higher genomic diversity in the imported group compared to both the Wuhan exposure and local transmission groups, indicating continuous genomic evolution during global transmission and imply that SARS-CoV-2 genomes may have high mutational tolerance.

TL;DR: HIV infection and antiretroviral therapy both led to mitochondrial disturbances in CD4+T cells and CD8-T cells; however, the abnormal changes in mitochondrial parameters in CD 4+T Cells were different from those in CD8+T cell caused by HIV infection and anti-viral therapy.

TL;DR: After a short recovery period, COVID-19 reinfections could occur in convalescent patients, even those with measurable levels of neutralizing antibodies as discussed by the authors, so effective vaccinations and protective public health measures are recommended for the convalescence COVID19 patients.
