Why are measles and polio outbreaks rising in the US?
Measles and polio outbreaks are increasing in the US mainly due to declining vaccination rates. Since 2019-2020, vaccination coverage has fallen below the herd immunity threshold of 95%, allowing these highly infectious diseases to spread again. Factors such as vaccine hesitancy and misinformation have contributed to this decline, making outbreaks more likely.

What’s causing the decline in vaccination rates?
The decline in vaccination rates is driven by a mix of vaccine hesitancy, misinformation, and complacency. Some parents and communities are choosing not to vaccinate due to fears about vaccine safety or mistrust in health authorities. This reduction in immunization coverage weakens herd immunity and increases the risk of outbreaks.
