According to a study from Obihiro, Japan, "The infectivity of the H9N2 virus to MDCK cells was time-dependently inhibited by Cu2+ at concentrations of 2.5-250 mc M. In 25 mc M Cu2+ solution, the virus titer decreased by approximately 3 and 4 log within 3 and 6 h, respectively. Compared to Cu2+, Zn2+ was much less effective in virus inactivation." "The H9N2 virus hemagglutinin activity was not affected by 2.5-250 mc M Cu2+. The H9N2 virus neuraminidase (NA) activity was drastically reduced by 25 mM Cu2+, marginally reduced by 250 mc M Cu2+, and not affected by 25 mc M Cu2+. Thus, we found that copper ions suppress the infectivity of influenza virus at lower...
