Early History of Measles
• First reports of measles date back to 700 AD, but the first scientific description was featured in Muhammad ibn Zakariya ar-Razi’s “Kitab fi al-jadari wa-al-hasbah” (The Book of Smallpox and Measles) c. 900 AD.
• This account was also first distinction from smallpox and chickenpox
Not just an artifcact of our grandparent’s generation
Remains a threat to children of the 3rd world
Symptomsa b
c
3 C’s
Only six structural proteins
From Me(asles) to Youa
The virus enters a host cell
From here on out…
Pick an organ, any organ
Clinical symptoms are present after incubation period

Not done yet
Viral shedding
The virus must return to the epithelium
Clinical diagnosis is most common
4 Day Fever
Observation of one of the 3 C’s(cough, coryza, conjuctivits)
The body fights back
Treatment is not strictly palliative
• Can not kill virus, but can alleviate symptoms– IV fluids– Fever medication– Antibiotics for secondary infetions (PSSE)– Vitamin A supplement
• Subacute sclerosing panencephalitis (PSSE)
Antibodies are able to ward off infection
• Live attennuated– Edmonston B or Schwartz stains90%
seroconversion-Often incorporated
with rubella and/or mumps vaccine
Bright Future
• The Measles Initiative- collaborative effort of WHO, UNICEF, ICRC, CDC, and UN + various private and public partners
• Mortality decreased by 74% between 2000 and 2007, from an estimated 750,000 to 197,000…this achieved the UN’s goal to reduce measles deaths by 90% by 2010, three years early
Side effects of vaccine?
