The hospitalized person has been discharged and is recovering, <a href=\"https:\/\/www.youtube.com\/watch?v=6Q19VKha0Wo\" target=\"_blank\" rel=\"nofollow noopener\" title=\"https:\/\/www.youtube.com\/watch?v=6Q19VKha0Wo\">Sidelinger said in a press conference Friday<\/a>. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Saying the situation is growing more urgent, he urged parents who are on the fence about the measles vaccine to talk to their child\u2019s health care provider about it. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Oregon has counted 20 known cases of measles so far this year, although state officials have repeatedly said they believe there are far more cases in Oregon going unreported. Sidelinger said there are mounting signs that transmission of the virus is becoming more widespread in Multnomah and Clackamas counties. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Just this week, the Oregon Health Authority announced that <a href=\"https:\/\/www.opb.org\/article\/2026\/04\/14\/measles-has-reached-a-portland-school-heres-why-health-officials-think-they-can-stop-it\/\" target=\"_blank\" rel=\"nofollow noopener\" title=\"https:\/\/www.opb.org\/article\/2026\/04\/14\/measles-has-reached-a-portland-school-heres-why-health-officials-think-they-can-stop-it\/\">a middle school<\/a>, a community college and an urgent care were all sites of potential measles exposures. <\/p>\n<p class=\"article-body__interstital article-body--padding f_primary m-none\">Related: <a href=\"https:\/\/www.opb.org\/article\/2026\/04\/03\/measles-oregon-cases-what-to-know\/\" rel=\"nofollow noopener\" target=\"_blank\">Measles cases in Oregon are ticking up. Here\u2019s what you need to know<\/a><\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">On April 11, public health officials identified Oregon\u2019s first outbreak this year that involved more than a single household, involving measles cases in Multnomah and Clackamas counties. The Centers for Disease Control and Prevention defines an outbreak as three or more linked cases. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">The <a href=\"https:\/\/www.opb.org\/article\/2026\/04\/03\/measles-oregon-cases-what-to-know\/\" target=\"_blank\" rel=\"nofollow noopener\" title=\"https:\/\/www.opb.org\/article\/2026\/04\/03\/measles-oregon-cases-what-to-know\/\">risk to the majority of the public is low<\/a> because a large majority of Oregonians have been vaccinated against measles. A single dose of the shot provides strong prevention against infection, and that protection lasts throughout a person\u2019s lifetime with little waning of immunity. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Sidelinger said he believes a major driver of transmission in Oregon is people who have the virus, aren\u2019t stick enough to seek medical care, and go on to spread it to other unvaccinated people.<\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">When people with measles are seen by a doctor or get a lab test, medical providers are required to report those cases directly to public health officials, so they can help identify anyone else who might have been exposed. If the virus is spread by people who do not seek medical care, there is little opportunity for public health to intervene. <\/p>\n<p>Protecting the unvaccinated<\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Measles is among the most contagious respiratory diseases in the world. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Unvaccinated pregnant people, unvaccinated people with a weakened immune system, and infants under 12 months old are at higher risk of catching measles if they are exposed, and also of getting a more serious infection. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Families that have conclusively decided not to vaccinate can help limit the spread of measles by quarantining themselves if they get sick, and by wearing a mask and calling ahead if they go to urgent care or a hospital. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">\u201cWe do rely on cooperation from others and, and people to take some simple steps to protect their family and loved ones,\u201d Sidelinger said. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">There is no specific antiviral treatment that can cure measles, though doctors can provide supportive care to keep patients hydrated and address symptoms like a fever. <\/p>\n<p class=\"article-body__interstital article-body--padding f_primary m-none\">Related: <a href=\"https:\/\/www.opb.org\/article\/2026\/04\/14\/measles-has-reached-a-portland-school-heres-why-health-officials-think-they-can-stop-it\/\" rel=\"nofollow noopener\" target=\"_blank\">Measles has reached a Portland school. Here\u2019s why health officials think they can stop it<\/a><\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">It can be serious in children under five years old. As many as one in every 20 children who gets measles develops pneumonia. In rarer cases, it can cause life-threatening swelling in the brain.<\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">\u201cPrevention is absolutely critical,\u201d said <a href=\"https:\/\/www.ohsu.edu\/providers\/dawn-nolt-md-mph\" target=\"_blank\" rel=\"nofollow noopener\" title=\"https:\/\/www.ohsu.edu\/providers\/dawn-nolt-md-mph\">Dr. Dawn Nolt<\/a>, a professor of pediatrics at OHSU. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">The United States has decades of experience with measles and a highly effective vaccine that doesn\u2019t require regular boosters.<\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">\u201cIf we can get one shot in everyone, we stop this in its tracks,\u201d Nolt said. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Sidelinger said he is particularly concerned that an unvaccinated person or people have brought measles into two schools this week. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Because measles spreads quickly to people who have not been vaccinated, those exposures rapidly expanded the pool of unvaccinated students who could contract the disease and then go on to unwittingly spread it to other classmates and staff. Per state policy, any unvaccinated student or staff person who is exposed to measles is excluded from school for several weeks \u2014 and that can add up for children exposed more than once. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">\u201cIt risks bringing to a halt the whole reason these students are at schools learning, academic achievement, social connection,\u201d Sidelinger said. <\/p>\n<p class=\"article-body__interstital article-body--padding f_primary m-none\">Related: <a href=\"https:\/\/www.opb.org\/article\/2026\/04\/03\/measles-oregon-cases-what-to-know\/\" rel=\"nofollow noopener\" target=\"_blank\">Measles cases in Oregon are ticking up. Here\u2019s what you need to know<\/a><\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">In South Carolina, the state with the largest outbreak so far in the United States, the vast majority of measles cases have been reported in children. Schools have been one major hub of transmission and some unvaccinated students have had to quarantine themselves repeatedly during that extended outbreak. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">In Oregon, about 6% of kindergarteners have a non-medical exemption allowing them to opt out of the first dose of the two-dose measles vaccine, which is otherwise required for school attendance. That amounts to more than 10,000 children in the state without protection against the virus. <\/p>\n<p class=\"article-body__text article-body--padding color_dgray m-none\">Measles was declared eradicated in the United States in 2000. But waning vaccination rates have allowed the virus to gain a foothold again. In 2025, the United States reported more than 2,000 cases of measles, and diagnoses are on track to far exceed that number this year. <\/p>\n","protected":false},"excerpt":{"rendered":"FILE &#8211; A medical doctor holds a vial of the combination measles, mumps and rubella vaccine at Prisma&hellip;\n","protected":false},"author":2,"featured_media":614955,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[34],"tags":[64,63,137,500,298497],"class_list":{"0":"post-614954","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-healthcare","8":"tag-au","9":"tag-australia","10":"tag-health","11":"tag-healthcare","12":"tag-oregon-disease"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/614954","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=614954"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/614954\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/614955"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=614954"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=614954"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=614954"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
