ICUs without air-conditioning could shield doctors from COVID-19: study

ICUs without air-conditioning could shield doctors from COVID-19: studyIntensive care units (ICUs) at hospitals treating COVID-19 patients should do away with air-conditioning to limit the risk of infecting doctors, a study from a top Indian research institute has said. "The recirculation of the air by the centralized air-conditioning systems is what has led to the significant infection of our committed medical fraternity and has also led to deaths of doctors and nurses," the study by the Indian Institute of Science in Bengaluru, considered one of the country's best science universities, said. Previous studies have suggested countries in hot climates should take care that indoor rooms are not dried out by overcooling with air conditioning, noting that keeping indoor humidity levels between 40% and 60% will help limit airborne transmission of the virus.
