A fast escalating outbreak of trafficking around Portland, Oregon, has led health care professionals in nearby Clark County, Washington, to declare an emergency emergency, as they warn that people infected with the highly contagious virus have visited schools and churches a dentist, a Costco, an Ikea and an Amazon download station.
Someone with measles was at Concourse D at Portland International Airport on January 7, the Public Health County Council prevailed. An infected person participated in a Portland Trail Blazer home game on January 11.
At the beginning of last week, there were only a handful of confirmed cases. On Friday the day the emergency was declared there was 1
The latest update came on Tuesday, when county council officials said they had confirmed 23 cases and investigated two more suspected cases. Most of those who have become ill had not been immunized.
The outbreak makes the concrete fear of pediatric epidemiologists that a citadel of the movement towards mandatory vaccination may be susceptible to the rapid spread of a potentially fatal disease.  "It's alarming," said Douglas J. Opel, pediatrician at Seattle Children's Hospital, in an interview with The Washington Post .
"Every time we have a disease outbreak that we have safe and effective vaccine against, it should raise a red flag."
State data show that 7.9 percent of children in Clark County were exempted during the 2017-2018 school year from vaccines required for access to kindergarten, which includes two doses of measles courses the Centers for Disease Control and Prevention says is 97 percent effective.
Only 1.2 percent of children had a medical dispensation, which means that almost 7 percent were not immunized for personal or religious reasons. Nationally, about 2 percent of the children went without the necessary immunizations for non-medical reasons.
The high proportion of non-medical exceptions for vaccines is what makes the Portland area, which sits across the Columbia River from Clark County, a "hotspot" for outbreaks, according to Peter J. Hotez, a pediatrician's and Dean of the National School's Tropical Medicine at Baylor College of Medicine in Houston.
"I have foreseen this for a while now," he said of the public health situation in Clark County. "It's really awful and really tragic and completely preventable."
Of the confirmed cases, 18 patients are between the ages of 1 to 10 years.
Twenty of the infected individuals had not been immunized against measles and the vaccination history of the other three remained unchanged. One person was in hospital.
Experts recommended that the outbreak could still be in its infancy. The incubation time for the virus is on average two weeks and it can spread four days before a rash makes the appearance apparent.
Since measles is among the most infectious of all infectious diseases, it is bound to flare up in areas with low vaccination rates, Hotez said.
He tracked this effect in a paper last year in Public Science of Science linking the number of philosophical exceptions that have climbed since 2009 in 12 of the 18 states that allow them to increase the outbreak.
The problem is particularly pronounced, there are papers in more than a dozen "hotspot metropolitan areas" including Portland and Seattle in the northwest, Phoenix in the southwest and Detroit in the Midwest.
Public health experts are alarmed about the geographical clustering of people who refuse to immunize themselves, which creates vulnerability despite the overall high vaccination rate.
In November, Asheville, North Carolina, gave another impetus to the anti-vaccination movement for the state's worst watercourse outbreak since a vaccine Before the infection became available more than two decades ago.
"Portland is a total train waste in terms of vaccine rates," Hotez said in an interview with Posten .
Resistance to mandatory vaccination in the Pacific Northwest date to Progressive Era and continues despite major medical breakthroughs.
The modern anti-vaccination movement – built on debunked research published in 1998 and thus associated with the measles, sheep and rubella vaccine, known as the MMR vaccine, with autism – is not exclusive to one side of the political divide, survey data suggests; It tends to find its most lively supporters in both extremes.
Fairs are a scary price to pay for affordable treatment on vaccination, warned Hotez and called the disease "one of the most serious infectious diseases known to mankind". After smallpox eradicated in 1980, measles became the world's foremost killer, he said.
In 2000, public health officers revealed measles in the United States because more than one year had passed without continuous transmission of the disease.
But new outbreaks provide evidence of dangerous backsliding during infection of the virus, Hotez said, blaming the anti-vaccination movement. "This is a self-inflicted wound," he said.
In 2015, a woman in northwest Washington died of pneumonia after receiving measles. It was the first American death from the virus since 2003.
Last year, the second highest number of reported cases of measles was seen since 2000, according to the CDC. A total of 349 cases were confirmed over 26 states and the District of Columbia, only surpassed by 667 cases in 2014.
Orthodox Jewish communities were at the center of several outbreaks last year in New York and New Jersey after unvaccinated travelers returned with the virus from Israel, which fought an outbreak.
Last year, Minnesota reported 75 cases of measles, mostly in a Somali community where the discredited theory that blamed autism on the MMR vaccine had taken hold.
Because measles is still endemic in parts of the world, Opel says. "Periodic introduction of people traveling is what causes frequent outbreaks here."
A high level of protection is required to prevent the transmission of the highly contagious virus, he added. Somewhere between 92 and 94 percent of the population must be immunized.
Clark County is already below that level, he noted, "before you influence other things like people just lack their meetings".
The county health department emphasized how easily the virus can spread, remaining as long as two hours in the air in a room where an infected person has been.
"If others breathe in the polluted air or touch a contaminated surface, then touch their eyes, nose or mouth, they may become infected," the county warned in a statement Tuesday.
"Messels are so contagious that if a person has it, 90 percent of the people near the person who is not immune will also be infected."
While the disease often begins with cold symptoms and rashes, doctors stressed that many infected persons suffer from additional complications, including pneumonia and, in more severe cases, inflammation of the brain called encephalitis
