The United States is facing its largest outbreak of measles since the virus was declared eliminated in 2000, centred on Pennsylvania, and the outbreak poses risks beyond US borders, according to Al Jazeera. Measles is highly contagious and can spread quickly among unvaccinated populations. Falling vaccination rates in some communities have allowed the virus to regain a foothold. Global health officials have warned that outbreaks anywhere can travel through international travel. The situation underscores the importance of maintaining high immunisation coverage.

Why it matters：Measles resurgence in a wealthy country shows how slipping vaccination coverage can create outbreaks with global spillover risk.
