This is due to the fact that each room has a separate ventilation system and one for every four rooms along the corridor.
Madrid (European Press).- The Institute of Environmental Diagnostics and Water, the Advanced Council for Scientific Research and Son Espases University Hospital in Majorca use a new method for measuring the presence of SARS. This allows them to confirm that the hospital’s air contains a higher level of virus than the room of COVID-19 patients.
This is because each room has its own ventilation system and one for every four in the corridor. The study was published in Environmental Research. It can be used to improve hospital ventilation, prevent infections, and improve the air quality.
This new method uses air filters to place in rooms, corridors and other wards in order to analyse the virus’ genetic material in a systematic manner. Research has shown that the most viral genetic material is found in the corridor next to the covid-19 patient’s room, rather than in the space itself, which is less ventilated. Thus, the virus can spread from one room into another.
Joan Grimalt (first author and IDAEA CSIC researcher) stated, “These results are important because there were many precautions taken when entering the space, but less precautions in the corridor.”
The research team explored different areas of the hospital. They visited the covid-19 ward, adjacent corridors, and corridors that are adjacent to the ICU wards for 19 patients without COVID; as well as outdoor terraces. Quantification was done using PCR technology.
Because hospitals have similar ventilation systems, the results can be used to transfer them to another hospital. First, you must monitor the levels of viral RNA within the hospital’s air. Grimalt clarified that if the result comes back positive, the ventilation system needs to be altered to suit the specificity of each hospital.
