Virions were preincubated with 1:100 dilutions of various body fluids and then allowed to infect epithelial cells. Forty-four hours postinfection, the cells were fixed with methanol and stained as described in Materials and Methods, and the number of infected cells was determined by fluorescence microscopy. “+” and “++” denote a 0 to 300% and a >300% increase in the number of infected cells, respectively, whereas a dash denotes no increase or a small decrease (<50%).
