LetterExperimental aerosol survival of SARS-CoV-2 in artificial saliva and tissue culture media at medium and high humidity.
SARS-CoV-2, the causative agent of the COVID-19 pandemic, may be transmitted via airborne droplets or contact with surfaces onto which droplets have deposited. In this study, the ability of SARS-CoV-2 to survive in the dark, at two different relative humidity values and within artificial saliva, a clinically relevant matrix, was investigated. ⋯ The decay rate and half-life was determined and decay rates ranged from 0.4 to 2.27 % per minute and the half lives ranged from 30 to 177 minutes for the different conditions. This information can be used for advice and modelling and potential mitigation strategies.

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) has stated that pulmonary rehabilitation (PR) is the most effective therapeutic intervention to reduce dyspnoea and to improve physical performance and quality of life for patients with obstructive lung disease. New innovative studies raised in the area of PR:1) Pulmonary fibrosis & asthma bronchiale - While PR is recommended for chronic respiratory diseases other than COPD (chronic obstructive pulmonary disease) in the respective disease-specific treatment guidelines, PR in some pathologies is underrated. For example, there is a growing body of evidence showing the effectiveness of structured and multidisciplinary PR programs in pulmonary fibrosis and asthma bronchial patients;2) Coronavirus SARS-CoV-2 - There is preliminary evidence that COVID-19 patients can benefit from a PR program. The current COVID-19 position paper of the German Respiratory Society e. V. (DGP) regarding PR recommendations suggests that early rehabilitative therapies are already indicated during hospitalisation on the normal or intensive care unit and that rehabilitative interventions should be continued after discharge as a follow-up treatment in PR centres in order to reduce long-term consequences of COVID-19 disease;3) Telehealth meets PR - To further improve the effectiveness of PR in COPD patients using recent technologies, a supplementary "digital exercise program" can contribute to greater benefits compared to PR alone.
