The CDC (Centers for Disease Control and Prevention) put out an early release of a new study that found a high level of coronavirus on medical workers’ shoes and floors. This study was conducted in a Chinese hospital in Wuhan that was dealing with many COVID-19 patients.
The study was called Aerosol and Surface Distribution of Severe Acute Respiratory Syndrome Coronavirus 2 in Hospital Wards, Wuhan, China, 2020. It found that in Huoshenshan Hospital in Wuhan, 94% of swabs that were taken from the ICU floor tested positive. Along with this, a shocking 100% of the swabs taken from one of the general wards that was treating patients that showed severe symptoms also tested positive for COVID-19.
It was also found that around 50% of the swabs taken from the ICU medical staffs’ shoes tested positive for Coronavirus. This concluded that ‘the soles of medical staff’s shoes might function as carriers’. Since the researchers also found the virus on the pharmacy floor in the hospital—where patients weren’t allowed. The authors wrote,
As medical staff walks around the ward, the virus can be tracked all over the floor, as indicated by the 100 percent rate of positivity from the floor in the pharmacy, where there were no patients.
They also believe that the distribution of the virus is also being caused by the respiratory droplets that fall onto floors and are then moved by gravity and airflow.
