Once again, unvaccinated people experience a measles outbreak - Seriously, just vaccinate your childrenThe Disneyland measles outbreak is directly attributable to vaccine-denier movements, the Centers for Disease Control and Prevention said today in a conference call with reporters.
From January 1 to 28, 84 people in 14 states have been reported as having measles, said Anne Schuchat, the head of the National Center for Immunization and Respiratory Diseases. Most of these cases — 56 people — are linked to the outbreak at Disneyland resort in Anaheim, where five employees are sick as well. The remainder were infected abroad and brought the disease back.
Measles was declared eliminated in the US in 2000, but they've been creeping back. From 2000 to 2010, there were usually about 60 cases a year. Last year, the CDC reported 644 cases — the highest number of measles infections since 2000. More adults are getting sick than in typical outbreaks, Schuchat said. The majority of people who got sick were unvaccinated.
"This is not a problem of the measles vaccine not working. This is a problem of the measles vaccine not being used," said Schuchat, the head of the National Center for Immunization and Respiratory Diseases, in the call. "It is frustrating that people have opted out of vaccination."
Some parents have avoided vaccinating their children after a now-discredited study by Andrew Wakefield suggested a link between vaccination and autism. The British Medical Journal has called Wakefield a "fraud," and the studies where he claimed to have found the link were retracted by the journal that published them, The Lancet. In multiple studies since Wakefield's original report, no link has been found between vaccines and autism.
That message hasn't made it to some people, though. Celebrities like Jenny McCarthy spread conspiracy theories — nicely detailed in Seth Mnookin's book, The Panic Virus — about "toxins" in vaccines that could cause autism in children. Our best evidence suggests that this is not what's happening. But parents don't seem to want to listen. Communities, especially in California, are springing up where significant parts of the population are unvaccinated.
And now, The New York Times is publicly wondering if measles are going to spell trouble for the Super Bowl (over 1,000 people in Arizona have been exposed; health authorities are engaged in contact tracing now). Anna Edney, of Bloomberg News, asked the CDC if they were worried about such a large crowd gathering, on the press call. Because — in case it's not obvious by now —measles is highly contagious. A person with measles doesn't show symptoms for four days before the rash appears, but is capable of infecting others. The virus is airborne, and can live for up to two hours on surfaces after being ejected from the body, according to the CDC. "Measles is so contagious that if one person has it, 90 percent of the people close to that person who are not immune will also become infected," the CDC writes.
