2 M ORBILLIVIRUS Infection of the respiratory system Paramyxovirus Negative-sense single- stranded RNA Envelope virus http://www.nature.com/nsmb/journal/v14/n12/images/nsmb1342-F1.jpg

3 M EASLES IN THE DEVELOPED COUNTRIES Vaccinations MMR ~ 18 months 2 nd Dose ~ 4-5 years Fatality Rate: 3 deaths/1000 cases 0.3% fatality

4 M EASLES IN THE DEVELOPING COUNTRIES WHO recommends two dosages: 6 & 9 months HIV Infection Fatality Rate: Can be as high as 28%!

6 What’s the problem? Why is there such a high fatality rate in the developing countries?

7 N O IMMUNIZATION ! “[Measles] is a highly contagious viral infection that kills more children than any other vaccine preventable disease” - UNICEF Lack of immunization due to three things: Poverty Poor health systems Lack of information
