The yellow fever is a viral disease that occurs for a short time, this disease is spread to the humans from mosquito's. Once it enters the blood stream through the bite of a mosquito it directly enters the blood stream and gets caught in the lymph nodes, these lymph nodes serve as sites for multiplication of these organisms.

First,  the yellow fever  virus  is  phagocytosed  by white  blood  cells.   The phagocytosed white  blood  cell  then travel  through  the  lymph  vessel. Since  lymph  node  contain  white blood and   filter  lymph,  the  yellow  fever  phagocytosed  with  white  blood  cell  establish  in  the  lymph  node.
