- The SARS-CoV-2 virus - responsible for the current coronavirus pandemic - can live on stainless steel surfaces for up to 72 hours, cardboard for up to 24 hours, and on copper for 4 hours and still be contagious.
- Other coronaviruses can live on metal, plastic, and glass surfaces for four to five days, and could persist for up to nine days depending on temperature and humidity.
- It's unclear how long viruses can live on fabric, but one study found that natural fabrics like wool and cotton are more likely to contain larger amounts of bacteria and fungi compared to silk and synthetic fabrics.
- To properly disinfect surfaces make sure you're using alcohol-based cleaners that are at least 70% alcohol for hard surfaces and washing fabrics in water that's at least 86 degrees Fahrenheit.
