US measles outbreak is greatest since the disease was declared removed in 2000

In general, there were 681 measles cases in 22 states this year, according to CNN's analysis on data from state departments and local health.

States reporting measles cases are Arizona, California, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Maryland, Massachusetts, Michigan, Missouri, Nevada, New Hampshire, New Jersey, Tennessee, Texas and Washington.
On Monday, US Centers for Control and Prevention of Disease reported 626 individual measles cases confirmed in 22 states. These include diseases reported by state health departments to the CDC until April 19 and therefore do not include cases reported since then.

The agency updates the number of measles cases every Monday.

Previously, the highest number of reported cases from removal was 667 in 201

disease caused by a virus that can spread to the air when an infected person coughs or sneezes or if someone directly interacts or distributes germs by touching both objects or surfaces. Symptoms of the disease may include fever, cough, nose, eye water and a rash of red spots.

Most cases in the United States have appeared in communities with low rates of viral immunization, according to public health officials. "I believe that parents' concerns about vaccines lead to undervaccination, and most of the cases we see are in indiscriminate communities," Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases at CDC, said in February at a hearing congressional hearing aid.

Nationally, the United States has high-sensitivity coverage coverage. The CDC says 91.5% of US children aged 19 months to 35 months have received at least one dose of measles, mumps and rubella vaccines in 2017, the latest year available.

"However, there are pockets of people who are vaccinated-hesitant," says Messonnier.

"Measles outbreaks occur when measles has reached these communities of people who have not been covered," he said. "The only way to protect against measles is to get immunized."

A source familiar with the measles situation in the United States previously told CNN that in 626 measles cases taken by federal officials last week, 72% were unvaccinated, and 18% had one known vaccination status. Among those who are not immunized, may be due to personal beliefs and medical reasons. The other 10% are vaccinated with either one or two doses

Of the 626 cases, 487 are in people 19 and younger.

The CDC identified that these outbreaks are associated with infected and infected travelers from other countries, including Israel, Ukraine and the Philippines.

For example, the outbreak of New York, which was declared a public health emergency last month, has started the information not yet covered was contaminated while visiting Israel, according to health officials.
A man from New York who was not contagious with contagious diseases visited Southeast Michigan, which spread illness to at least 38 people there, according to Lynn Sutfin, official public information for Michigan Department of Health and Human Services.

American measles history [19659007] In 1912, measles became an exceptional disease across the country in the United States, which meant that health care providers and laboratories reported diagnosed cases. During the first decade of reporting, an average of approximately 6,000 measles deaths was reported annually.

In the 1950s, researchers removed a patient's measles virus, and in the 1960's, a vaccine. The vaccine is licensed and then used as part of a vaccination program.

Before the introduction of the measles vaccination program in the United States in 1963, approximately 3 million to 4 million people have been infected every year nationwide, according to the CDC. After that, cases and deaths from measles in the United States and other developed countries have fallen. There were 963 cases reported in the United States in 1994 and 508 in 1996.

In 2000, in only 86 cases, measles was declared to be removed from the United States, meaning no immediate disease transmission more than 12 months.

From 2000, the annual number of measles cases has reached 37 people in 2004 to 667 in 2014.
The measles, mumps and rubella vaccines – known as the MMR vaccine – are very effective. One dose is about 93% effective in preventing measles if you are in contact with the virus. Two doses are about 97% effective.

The experts recommend that children receive the vaccine in two doses: first between 12 months and 15 months and one second between 4 and 6 years old.

In any medicine, including vaccines, there is a chance of reactions, according to the CDC. They are often mild and leave themselves, but there is a "remote opportunity" of effects and even serious injuries.

The experts say that benefits are greater than those of the measles vaccine.
