Air quality and air flow of the indoor spaces are critical to ensure clean air and prevent the transmission of virology.
Understanding how COVID-19 spreads
Before delving into the specifics of indoor transmission, it is essential to understand how COVID-19 spreads generally. According to the Centers for Disease Control and Prevention (CDC), COVID-19 primarily spreads through respiratory droplets that are released when an infected person talks, coughs, or sneezes. These droplets can land in the mouths or noses of people nearby or be inhaled into the lungs. The virus can also potentially spread by touching a surface contaminated with the virus and then touching the mouth, nose, or eyes. However, the CDC reports that this is not the primary way the virus spreads. The World Health Organization recommends using air disinfection and increasing Air Changes Per Hour (ACH) with a HEPA air cleaner as well as checking air quality to improve the air flow by ventilation strategies.
It is important to note that people who are infected with COVID-19 can spread the virus even if they do not have symptoms. This is why wearing face coverings and practicing social distancing is crucial in preventing the spread of the virus. Additionally, the CDC recommends frequent hand washing with soap and water for at least 20 seconds as another effective way to prevent the spread of the virus. Clean air flow, good air ventilation and UVGI systems will also help in air disinfection.
It is also important to be aware of the potential for airborne transmission of COVID-19. This occurs when small particles containing the virus linger in the air and are inhaled by others. While this type of transmission is less common than respiratory droplets, it can occur in certain situations, such as in enclosed spaces with poor ventilation. This is why it is important to wear masks and avoid crowded indoor spaces, especially if they are poorly ventilated. Air quality is important and can be improved by using disinfectant, opening windows or using an air conditioning system with a HEPA air cleaner. Window air conditioner is one of the best ventilation strategies for keeping the air clean and maintaining the air ventilation standards.
What is indoor transmission?
Indoor transmission occurs when individuals in a shared indoor space inhale the virus from the air. This type of transmission happens more readily in enclosed spaces with poor ventilation where the virus can build up and linger in the air. The risk of transmission is highest in settings where people congregate for an extended period, such as in restaurants, gyms, and religious services. The World Health Organization recommends using higher efficiency air filters and optimizing ventilation and air flow, and considering the use of air disinfection, window air conditioner, guv and hepa air cleaner units and other ventilation strategies to improve air quality.
