โ๏ธThe high risk may be due to change of room use, age, condition of air handling plant, lack of maintenance, challenges with effective use of natural ventilation or other.
โ๏ธImportant to bring these facilities up to the minimum specification of current standards.

#InfectionControl
'๐ฉ๐ฒ๐ป๐๐ถ๐น๐ฎ๐๐ถ๐ผ๐ป is the process by which โfreshโ air is intentionally provided to a space and stale air is removed - achieved by mechanical systems using ducts and fans, or natural ventilation most commonly provided through opening windows.' @NHSEngland
#InfectionControl
'Ventilation is an important feature in the control of airborne infection. However, the emergence of #SARSCoV2 as a highly contagious virus has demanded new and innovative solutions to safeguard patients, staff and visitors.' @NHSEngland england.nhs.uk/publication/spโฆ
'Ventilation is an important feature in the control of airborne infection.'
Quote: 'The COVID-19 #pandemic has shown that greater attention must be paid to the improvement and maintenance of #ventilation in #healthcare settings.' @NHSEngland
'The focus on ventilation has also highlighted areas of high risk due to poorly performing and inadequate ventilation, particularly in older hospitals and other healthcare settings such as primary care and dental suites, which increase risks of nosocomial infections.' @NHSEngland
#Ventilation #InfectionControl
'Weather conditions, external noise and air pollution and restricted window openings for safety affect the ability to open windows and means that #ventilation in some settings can fall below recommended rates.' @NHSEngland
