ABSTRACT
In this work, SARS-CoV-2 infectivity after UV-C exposure of porous and non-porous surfaces was assessed under controlled environment conditions. The irradiance of a setup of UV-C lamps, placed indoors was studied in detail as a function of the geometry and the distance to the surface. In the presence of living beings, the external UV-C lamps are turned off, and the UV-C lamps mounted inside the disinfection chamber are kept active, allowing a continuous air disinfection and a decreased risk of indoor transmission. © 2022 17th International Conference on Indoor Air Quality and Climate, INDOOR AIR 2022.

ABSTRACT
Introduction: The pandemic of COVID-19 imposed the elaboration and dissemination of content about protection and prevention of the disease for different audiences. Objective: Analyze videos released by government institutions related to COVID-19 protection and prevention for people with disabilities (PWD) in light of Cognitive Theory of Multimedia Learning (CTML). Methods: Documentary research, carried out on the official websites of the governmental spheres of Brazil and on the YouTube video sharing platform. Results: Identified 33 videos produced in 2020 and their contents presented understandable language, clear and varied colors, devoid of figures or animations. Of these, 29 videos included the Libras interpreter and one used audio description of the images. Two categories were identified: Protective Measures of COVID-19 in PWD and Preventive Measures of COVID-19 in PWD. According to the principles of the Theory it was observed adequacy in the conveying of information on the protective measures regarding the principles of coherence, signaling, spatial and temporal contiguity, pre-training, modality, multimedia and customization in the language on individual and collective protection measures, educational inclusion and accessibility to rehabilitation assistance by telehealth. In the preventive measures, the principles of multimedia, personalization, voice, image, signaling, and personalization are attended to, as hand washing, respiratory etiquette, correct use of the face mask and with lip visor, facing COVID-19 for intellectual PWD, hygiene of support equipment, and protocols used in inclusive residences were explained. Conclusions: The principles of CTML contributed satisfactorily to the visual materials published about COVID-19 for PWD, however, this communication modality needs a greater reach to the interested public. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
The COVID-19 pandemic is a novel infectious disease pandemic with the agent SARS-CoV-2 virus which is currently affecting and causing damage globally.

After completely applying the medical prevention and active control, Vietnam has the ability to take control of the outbreak of COVID-19 as a recent of WHO assessment. Vietnam has been reported as an effective country for prevention and control the outbreak of COVID-19. We retroactive reviewed our experience with 16 positive cases isolation. This article aims to present the first cohort of COVID-19 patients updated to Feb 28th, 2020 in Vietnam and sharing the national response to the pandemic.
