Experimantal Congo virus (Ib -AN 7620) infection in primates

Three primates inoculated with Congo virus (CV) developed viremia. The animals showed neither any rise in rectal temperature, nor signs of overt disease; however, in one of them pruritus and rash were observed. Skin biopsy revealed vasculitis and hemorrhage. By complement fixation, neutralization and gel diffusion tests CV antibodies were demonstrated in the convalescent sera of the three animals.
