Potential role of fomites in the vehicular transmission of human astroviruses

In this study astrovirus showed considerable persistence when dried onto porous and nonporous material. On china it survived for 60 days at 4ºC and 7 days at 20ºC. On paper at 4ºC, astrovirus infectivity was detected after 90 days, and for up to 60 days at 20ºC. Applied and Environmental Microbiology 2001;67:3904-3907.
