Improving indoor ventilation and air quality will help us all to stay safe 
COVID-19 is in the air: Why are we still ignoring the importance of ventilation?
The main transmission mechanism of the SARS-CoV-2 virus is airborne, particularly in poorly ventilated indoor environments. Recognizing the importance of this mechanism has taken a long time, despite
Indicators for Risk of Airborne Transmission in Shared Indoor Environments and their application to COVID-19 Outbreaks
Two simple parameters are proposed as indicators of infection risk for COVID-19 indoor infection risk that combine the key factors that control airborne disease transmission indoors: virus-containing aerosol generation rate, breathing flow rate, masking and its quality, ventilation and air cleaning rates, number of occupants, and duration of exposure.
Practical Indicators for Risk of Airborne Transmission in Shared Indoor Environments and Their Application to COVID-19 Outbreaks.
COVID-19 outbreaks show a clear trend that is consistent with airborne infection and enable recommendations to minimize transmission risk, and it is important that future outbreak reports include information on masking, ventilation and aerosol-removal rates, number of occupants, and duration of exposure, to investigate airborne transmission.
Home energy efficiency under net zero: time to monitor UK indoor air
Giorgos Petrou and colleagues argue for systematic large scale monitoring of indoor air to avoid unintended harms to health from home energy efficiency programmes
Impact of supplementary air filtration on airborne particulate matter in a UK hospital ward
A natural experiment that occurred when an air filtration unit on an inpatient ward for older people was accidentally switched off suggests that social distancing measures alone cannot prevent nosocomial transmission of SARS-CoV-2.

A SARS-CoV-2 Cluster in an Acute Care Hospital
This study describes the detection, mitigation, and analysis of a large cluster of SARS-CoV-2 infections in an acute care hospital with mature infection control policies and discusses insights that
How can airborne transmission of COVID-19 indoors be minimised?
SARS-CoV-2 Infection Among Health Care Workers Despite the Use of Surgical Masks and Physical Distancing—the Role of Airborne Transmission
This report reports for the first time SARS-CoV-2 nosocomial infections despite using surgical masks and physical distancing, and may provide possible evidence for airborne transmission of Sars-Cov-2.
It Is Time to Address Airborne Transmission of Coronavirus Disease 2019 (COVID-19)
There is significant potential for inhalation exposure to viruses in microscopic respiratory droplets at short to medium distances, and the use of preventive measures to mitigate this route of airborne transmission is advocated.
The airborne lifetime of small speech droplets and their potential importance in SARS-CoV-2 transmission
Observations confirm that there is a substantial probability that normal speaking causes airborne virus transmission in confined environments.
Recognition of aerosol transmission of infectious agents: a commentary
This review considers the commonly used term of ‘aerosol transmission’ in the context of some infectious agents that are well-recognized to be transmissible via the airborne route, and discusses other agents, like influenza virus, where the potential for airborne transmission is much more dependent on various host, viral and environmental factors, and where its potential for aerosol transmission may be underestimated.
Short-range airborne route dominates exposure of respiratory infection during close contact
In this study, the exposure to exhaled droplets during close contact with an infected person and the mechanism of exposure to droplets expired at close contact are studied.
The Potential Future of the COVID-19 Pandemic: Will SARS-CoV-2 Become a Recurrent Seasonal Infection?
Three key considerations will make achieving herd immunity against COVID-19 challenging and some public health officials suggest that achieving winter herd immunity in the presence of new more contagious variants will require more than 70% to 80% of individuals to be immune.
Control strategies for indoor environment quality and energy efficiency—a review
The demand for better indoor environment has led to a wide use of heating, ventilating and air conditioning (HVAC) systems. However, this demanding cannot be sustained without a strategy to reduce
