From Emedicina:
Bilateral posterior cervical adenopathy is most highly suggestive of EBV infectious mononucleosis.
Some of the causes of heterophile-negative infectious mononucleosis may manifest with bilateral posterior cervical adenopathy, eg, rubella, but other signs and symptoms serve to differentiate these patients from those with EBV infectious mononucleosis. Patients with rubella have other associated findings, including the distribution and progression of the rash and occipital or preauricular adenopathy; usually, they do not have generalized adenopathy, and liver involvement is not a feature of rubella infections.
http://www.merck.com/mrkshared/mmanual/section19/...
Tender swelling of the suboccipital, postauricular, and postcervical glands is characteristic of Rubella.
So Rubella and EBV have posterior cervical adenopathy, but not measles.
In atypical measles syndrome, there is hilar adenopathy.

chicken pox--Crops of vesicles in various stages of development
maculopapular rash, head downwards
rubella..3 days measles, post occipital lymphadenopathy
measles--9 days
roseola ( exanthem subitum due to HHV 6)--FEver resolves ,then onset of rash, unlike the previous 2
