The U.S. will likely lose its measles elimination status. Here's what that means
U.S. Measles Cases Rise Above WHO Threshold. Vaccines Still Work.
What Happened
The U.S. is likely to lose its measles elimination status from the World Health Organization due to sustained transmission over 12 months. The WHO requires countries to have no continuous transmission for 12 months to maintain elimination status. Cases have increased due to declining vaccination rates in some communities.
Historical Context
The U.S. first achieved measles elimination in 2000 after decades of vaccination campaigns. Other developed countries have lost and regained elimination status: the UK lost it in 2008 and regained it in 2017. Measles elimination is a technical WHO designation - it doesn't mean the disease will spread uncontrolled. The measles vaccine remains 97% effective with two doses, unchanged since its introduction.
What's In Your Control
Whether you and your family are vaccinated according to CDC guidelines. Whether you verify your vaccination status with your doctor. Avoiding unvaccinated travel to outbreak areas if you're immunocompromised.
Does This Require Action?
If you're vaccinated: awareness only. If unvaccinated or unsure: consult your doctor about vaccination status. Parents should ensure children are up to date on MMR vaccines.
