U.S. Health and Human Services Secretary Robert F. Kennedy Jr. visited the epicenter of Texas’ still-growing measles outbreak on Sunday, the same day a funeral was held for a second young child who was not vaccinated and died from a measles-related illness.

The second young child died Thursday from "what the child’s doctor described as measles pulmonary failure,” and did not have underlying health conditions, the Texas State Department of State Health Services said Sunday in a news release.
