G: TLDR: Before the vaccine, measles killed about 1 in every 500 to 1,000 infected children in developed countries. In poorer regions, the fatality rate could be as high as 1 in 10.

Details:

• In developed countries (like the U.S. pre-1963), the case fatality rate for measles was typically 0.1% to 0.2% — that's 1–2 deaths per 1,000 cases.
• In malnourished or low-resource settings, especially where Vitamin A deficiency was common, fatality rates could rise to 5–10% or more.
• Besides death, measles caused severe complications in a significant portion of children — including pneumonia, encephalitis, and permanent brain damage.

G: As of the most recent data:

• 2020: Approximately 1 in 36 (2.8%) of 8-year-old children in the U.S. were identified with autism spectrum disorder (ASD), according to the CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network. citeturn0search0

• 2022: A study published in JAMA Network Open reported that among 5- to 8-year-olds, the prevalence was 30.3 per 1,000 children, equating to about 1 in 33 children. citeturn0search1

These figures indicate a rising trend in autism diagnoses among children in recent years. The increase may be attributed to heightened awareness, improved screening practices, and changes in diagnostic criteria. citeturn0search0

It's important to note that prevalence rates can vary based on factors such as geographic location, socioeconomic status, and access to healthcare services. For instance, the CDC reported that ASD prevalence among 8-year-olds in 2020 ranged from 1 in 43 in Maryland to 1 in 22 in California. citeturn0search2
