Objectives: To summarise the evidence on the duration of infectiousness of individuals in whom SARS-CoV-2 ribonucleic acid is detected. Methods: A rapid review was undertaken in PubMed, Europe PubMed Central and EMBASE from 1 January 2020 to 26 August 2020. Results: We identified 15 relevant studies, including 13 virus culture and 2 contact tracing studies. For 5 virus culture studies, the last day on which SARS-CoV-2 was isolated occurred within 10 days of symptom onset. For another 5 studies, SARS-CoV-2 was isolated beyond day 10 for approximately 3% of included patients. The remaining 3 virus culture studies included patients with severe or critical disease; SARS-CoV-2 was isolated up to day 32 in one study. Two studies identified immunocompromised patients from whom SARS-CoV-2 was isolated for up to 20 days. Both contact tracing studies, when close contacts were first exposed greater than 5 days after symptom onset in the index case, found no evidence of laboratoryconfirmed onward transmission of SARS-CoV-2. Conclusion: COVID-19 patients with mild-to-moderate illness are highly unlikely to be infectious beyond 10 days of symptoms. However, evidence from a limited number of studies indicates that patients with severe-to-critical illness or who are immunocompromised, may shed infectious virus for longer .

A key consideration in the Covid-19 pandemic is the dominant modes of transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. The objective of this review was to synthesise the evidence for the potential airborne transmission of SARS-CoV-2 via aerosols. Systematic literature searches

The large number of variables and lack of standardisation of reporting makes data synthesis challenging, however, people with MS display considerable deficits in postural control compared to healthy controls regardless of task condition or complexity.

In addition to the difficulties encountered by non-dancing university students, university-level dancers may encounter a range of challenges due to their status as aesthetic athletes. This pilot study compares the biopsychosocial characteristics of contemporary dance (CD) and Irish dance (ID) university students. CD (N = 30) and ID (N = 27) participants from institutions in Ireland and the United Kingdom were screened using a host of subjective and objective tools to establish baseline biopsychosocial characteristics. Participants also provided extensive information regarding their injury history over the previous year. The groups were compared using simple descriptive statistics, independent t-test or Mann Whitney U tests and chi-square tests as appropriate. CD participants danced for significantly more hours each week (p < 0.001) than the ID group, who spent significantly less time warming up (p < 0.001) and more time engaged in weekly non-dance-related physical activities (p = 0.022). CD participants performed significantly better that the ID group on the Star Excursion
