Michigan officials laud childhood vaccination programs

According to Michigan health officials, a preliminary disease case count report for 2011 indicates that childhood vaccination programs continue to work against chickenpox, mumps and pertussis.
The number of cases of all three diseases declined last year, based on totals included in the final weekly disease report of the year. Chickenpox cases have fallen sharply in the past five years and there were only 24 mumps cases, half of the 2010 total, the Associated Press reports.  
"I think we can say the childhood vaccines do work," Corinne Miller, a state epidemiologist with the Michigan Department of Community Health, said, according to the AP. "You can go disease after disease where we have a vaccine, and you'll see the drop in childhood illness."
The report also indicated that sexually transmitted disease cases were on the rise. Much of the growth is a result of chlamydia, which rose to 48,644 reported cases in 2011, up from 47,977 in 2010 and 38,759 in 2007. The rising count may be the result of increased screening and detection, rather than a spread of the disease.
"In the last few years, there has been a significant increase in resources for chlamydia testing for women," Katie Macomber, a state epidemiologist, said, according to the AP.
If left untreated, chlamydia can lead to pelvic inflammatory disease and infertility in women.
