A raging measles outbreak in West Texas, which has so far killed one child, has not abated and may have taken root in New Mexico, state health officials reported Friday.

The outbreak has sickened nearly 200 people — roughly 40 more cases than were reported Tuesday — and has left 23 hospitalized in West Texas. Local health officials say even that number may be an undercount.

Health and Human Services Secretary Robert F. Kennedy Jr. has faced criticism for his handling of the worsening outbreak. A prominent vaccine skeptic, Kennedy has offered muted support for vaccination and has emphasized untested treatments for measles, like cod liver oil.

The outbreak has largely spread within a community of Mennonites in Gaines County, Texas, who historically have had lower vaccination rates and often avoid interacting with the health care system.

In a news release Friday, Texas health officials wrote that more cases are “likely to occur,” because of the contagiousness of the virus.
