Population groups studied samples subject groups were distribution into (3) groups including ( 10-20, 21-31 and 32-42) year ,this distribution was made depending on their age and clinical status of both gender. The 21-31 year of infected patient high infection of virus at a rate 47.59% whilst 10-20 year percentage ( 36.59%) and 32-42 year percentage (15.46%).

Chemokines are considered pro-inflammatory through infection was reduced as compared to concentration anti-inflammatory .The study appear high titer of Homeostatic after 7-21 day including (CCL27 , CCL19 and CXCL13) comper Inflammatory including (CCL3 , CCL11 and CXCL8) .Yet CCL27 after 14 day (0.82±0.22) high titer camper with CCL19(0.80±0.24) and CXCL13(0.78±0.22) of virus infected group in the level of probability (P <0.05) while, CCL11 , CCL3 and CXCL8 were dcreased to reach (0.76±0.25, 0.74±0.24 and 0.72±0.26) pg/ml respectively in the plasm of patients compared with the control group.
