Answer

Animal models show that Langerhans cells are the first cellular targets of HIV, which fuse with CD4+ lymphocytes and spread into deeper tissues. In humans, rapid occurrence of plasma viremia with widespread dissemination of the virus is observed 4-11 days after mucosal entrance of the virus.
