The aim of this study was to determine the infectivity of a model human coronavirus HCoV-OC43 in the presence of climbing chalk powder on a dry plastic surface. The stability of HCoV-OC43 on a plastic surface dusted with climbing chalk powders (magnesium carbonate, calcium carbonate or a blended chalk) was determined by titration on BHK-21 fibroblast cells. No chalk and no virus controls were included. HCoV-OC43 was stable on the plastic surface for 48 h. The stability of HCoV-OC43 was significantly (P </= 0.05) reduced in the presence of magnesium carbonate, calcium carbonate and the chalk blend; the infectivity was reduced by >/=2.29 log(10) 50% tissue culture infective dose (TCID(50) ) immediately upon on contact and by >/=2.46 log(10) TCID(50) within 1 h of contact. These findings suggest that the infectivity of coronaviruses is reduced by climbing chalk, limiting the risk of potential fomite transmission.
