We identified this PDF through public web research and acquired the frozen research copy only from the publisher's official URL. It was not supplied by a customer, user, or partner and was not uploaded through DocAccessible. This page is the reviewed HTML conversion of the official CDC publication, produced for the PDF-to-HTML benchmark corpus. Automated diagnostics and the completed project-owner review record are published below. This is not an independent audit, certification, or conformance claim. The publisher's PDF linked above remains the document of record.

Conversion method and notes

Method: text extraction with manual semantic markup.

  • Source is a single-page infographic; the symptom icons and the four severity statistics were rendered as unordered lists so their full text is preserved.
  • The masthead 'MEASLES / IT ISN'T JUST A LITTLE RASH' and its lead line were combined into an opening statement paragraph.
  • The printed cdc.gov/measles address is kept as a working link.

The source score measures normalized text retention and local order. Visual coverage compares aligned rendered regions and object representation. Neither automated result independently establishes visual equivalence, semantic correctness, or accessibility conformance. Human review is a separate, exact-revision project-owner record.

Document content

Measles: It Isn’t Just a Little Rash. Measles can be dangerous, especially for babies and young children.

Measles symptoms typically include:

  • High fever (may spike to more than 104°F)
  • Cough
  • Runny nose
  • Red and/or watery eyes
  • Rash (breaks out 3-5 days after symptoms begin)

Measles can be serious.

Measles can cause severe health complications, including pneumonia, swelling of the brain (encephalitis) and death.

  • 1 out of 5 people who get measles will be hospitalized.
  • 1 out of every 1,000 people with measles will develop brain swelling, which may lead to brain damage.
  • 1 out of every 20 children with measles will get pneumonia, the most common cause of death from measles in young children.
  • 1 to 3 out of 1,000 people with measles will die.

Long-term complications

A very rare, but deadly disease called subacute sclerosing panencephalitis can develop 7 to 10 years after a person has recovered from measles.

You have the power to protect your child.

Provide your children with safe and long-lasting protection against measles by making sure they get the measles-mumps-rubella (MMR) vaccine. Talk to your healthcare provider.
