No, treat with doxycycline, rifampin if preggers. See clinical improvement as soon as 24 hrs. after administration of doxycylcine. |

age would be different (all age groups) risk factor: immunocompromised patient, day care (environment)...those highly at risk are 2 y/o or less, presentation would be diff in that there would be aminotransferases higher in CMV...EBV present more as a localized disease. Less exaggerated lymphadenopathy and spleenomegaly, |

Definition
No b.c within the early disease the person has not yet had the time to produce the Ab, so it will be (-) and then after 2 wks, should be (+) |
