Measles Incidence/Vaccine Coverage in the US
159+ cases of measles have been reported this year according to the CDC. All have been linked to contact with an imported case, ie. exposure to an infected immigrant child. States most affected are New York (65) and Texas (23) . The measles outbreak of 1989-1991 involved 55,000 cases with 123 deaths.
The CDC has recently reported that vaccine coverage for preshcool children is high with rates at 90-92%, for MMR, polio, hepatitis B and chickenpox (varicella). Rates for DTaP, Hib, and PCV (pneumococcal ) are at 81-83%. 80% of the under/unvaccinated refuse the vaccine due to philosophical, religious or safety concerns. These groups of children would be at risk of contracting measles, for instance, if exposed to an imported case.
