Measles is a contagious virus that spreads through the air as a result of coughing and sneezing. Symptoms such as fever, a rash all over the body, stuffy nose and redness of the eyes usually disappear without treatment within two or three weeks. According to the US Centers for Disease Control and Prevention, one or two out of 1,000 children with measles will die from complications.
In 1978, CDC set a target to eliminate measles in the United States by 1982. Measles was declared eradicated — as determined by the absence of a constant transmission of the disease for more than 12 months — from the United States in 2000.
But recently there has been an increase in the number of unvaccinated children. The proportion of children who did not receive vaccine doses by the age of 2 increased from 0.9% among children born in 2011 to 1.3% among children born in 2015, reports the CDC in October.
“It's a big number,” said CNN's chief medical correspondent, Dr. Sanjay Gupta, on Monday. “As soon as you start dropping below 95% of the vaccination, you begin to lose herd immunity. I have immunity because I received the vaccine, but I also protect the people around me because of the herd. As soon as you start falling as low as you (in Clark County) you lose this herd immunity, and this is also part of the problem, ”he explained.
The CDC recommends that people be vaccinated against measles, mumps and rubella to protect against these viruses. Typical recommendations are that children should receive two doses of the MMR vaccine: the first between 12 and 15 months of age and the second between 4 and 6 years of age.
