Title: Human Coronavirus 229E Remains Infectious on Common Touch Surface Materials Document date: 2015_11_10
ID: 4d4l6mzl_15
Snippet: Exposure to copper surfaces results in morphological changes to human coronavirus particles visible in transmission electron microscopy (TEM). There was a significant difference in appearance between purified HuCoV-229E exposed to stainless steel and that exposed to copper surfaces (Fig. 6 ). On stainless steel, uniform virions were visible following a 10-min exposure (Fig. 6A ), but on copper, clumps of damaged virus particles (Fig. 6B ) as well.....
Document: Exposure to copper surfaces results in morphological changes to human coronavirus particles visible in transmission electron microscopy (TEM). There was a significant difference in appearance between purified HuCoV-229E exposed to stainless steel and that exposed to copper surfaces (Fig. 6 ). On stainless steel, uniform virions were visible following a 10-min exposure (Fig. 6A ), but on copper, clumps of damaged virus particles (Fig. 6B ) as well as a few intact particles could be seen. The extent of damage increased upon further exposure to copper (Fig. 6C ).
