Findings: National Institutes of Health, Centers for Disease Control and Prevention
A new study by the National Institutes of Health, Centers for Disease Control and Prevention, and scientists at Princeton and UCLA is giving the first look at the current virus’s ability to survive on surfaces. The results show that the previous estimations weren’t far off. FINDINGS “The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel,” A summary by the NIH reads. “The results provide key information about the stability of SARS-CoV-2, which causes COVID-19 disease, and suggests that people may acquire the virus through the air and after touching contaminated objects.” Scientists tested the virus on five different environments: Aerosol Copper Cardboard Stainless Steel Plastic The main findings represent how long the virus CAN survive, but that doesn’t mean that it always WILL: Aerosol: Less than 3 hours Copper: Less than 4 hours Cardboard: Less than 24 hours Stainless Steel: Less than 72 hours Plastic: Less than 72 hours Officials said the virus’s survivability is impacted by outside factors like temperature and humidity, but the test was conducted in a controlled environment. The temperature was kept between 70-73 degrees and a 40-percent humidity was maintained.
