As winter continues and energy costs rise, it is tempting to try and keep residents warm and fuel costs down by hunkering down until the weather gets warmer. But keeping all the windows and doors shut may not be the best idea: all homes need ventilation and care homes...
This informative video has been created using findings from the PROTECT COVID-19 National Core Study to show the value of using control measures to reduce the spread of COVID-19. Many thanks to the researchers from across the PROTECT study for their contribution to...
The benefits of ventilation are greatest in rooms where people spend more time together (>30 min).In many buildings the air distribution in rooms is poor, and stagnant spaces may create zones of higher risk.There is evidence from several studies that air movement...
Although there is no “safe” ventilation rate to prevent the spread of pathogens altogether, ventilation that maintains lower CO2 levels (under 800ppm) is considered a lower risk environment. High CO2 levels (routinely above 1500ppm) are often a sign of poor...
If you are responsible for managing workplace buildings, it would be useful to provide information about how rooms are ventilated, and reassurance around how systems are checked and maintained. Surveys of employees and business owners carried out during the PROTECT...
While there are no specifications for infection control, there are principles you can follow to reduce risks:Ensuring that the system provides sufficient fresh air ventilation for the occupants.Ensuring that the system is regularly maintained and that there is a...
Some mechanical ventilation systems recirculate part of the air in the room. This can increase risks of exposure to respiratory viruses unless the system has devices to remove pathogens such as high-grade filters or UV light. Related Contact...
Ventilation is not the same as air conditioning. In some buildings mechanical ventilation systems also provide heat and cooling, but in others stand-alone air-conditioning units are installed to cool the air – these are very common in offices and hospitality...
Good ventilation can significantly reduce the risk of exposure to airborne virus particles, providing there is enough fresh air flow or good filtration.There is evidence from Covid-19 outbreak studies that in buildings with better ventilation, infection rates are...
Transmission via surfaces is possible but it is likely to account for a relatively small proportion of transmission for Covid-19. When measured in the vicinity of an infected person it has been possible in a very small number of studies to find live virus on a...
