The findings: The virus, or at least its genetic signature, abounds. It was detected on the floors next to the beds of patients, floors outside patient rooms and surfaces inside the rooms.

A new study published in the journal Microbiome describes how SARS-CoV-2 persists on surfaces in hospitals.
Researchers swabbed patient room surfaces before, during and after occupancy, and repeatedly collected samples from the skin, noses and stool of Covid-19 patients and their health care workers over time. In total, they tested 972 hospital-associated samples for traces of SARS-CoV-2 over two months.
Their findings: The virus, or at least its genetic signature, abounds. It was detected on the floors next to the beds of patients with Covid-19 (39% of samples tested), floors outside patient rooms (29%) and surfaces inside the rooms (16%). SARS-CoV-2 detection tended to be highest in the first five days after a patient’s onset of symptoms.
