US Measles Outbreak Hits 35-Year High
The United States is experiencing its worst measles outbreak in 35 years, with over 2,300 confirmed cases.
This outbreak is happening because fewer people are getting vaccinated.
Measles can cause fever, rashes, and serious complications like pneumonia and brain inflammation.
In 2000, measles was declared eradicated in the US thanks to vaccines, but it has come back due to vaccine hesitancy and misinformation.
Experts are worried that if vaccination rates keep dropping, other preventable diseases could also make a comeback.
The US is experiencing its worst measles outbreak in 35 years with 2,318 confirmed cases in 2026.
Measles can cause fever, respiratory symptoms, skin rashes, and severe complications like pneumonia and brain inflammation.
The outbreak is driven by declining vaccination rates and growing distrust in health authorities.
Vaccine hesitancy and misinformation have led to a surge in non-medical vaccine exemptions, particularly since the Covid-19 pandemic.
Experts warn that if vaccination rates continue to drop, other vaccine-preventable diseases could also see an increase in cases.
