Worldwide, there were an estimated 10.3 million cases of measles in 2023, a 20-percent increase from 2022, according to new estimates from the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC). Inadequate immunization coverage globally is driving the surge in cases.

The Centers for Disease Control and Prevention (CDC) has confirmed a human infection with avian influenza A(H5N1) (H5N1 bird flu) in a child in California.

New CDC population data from 2023 show that in 23 states more than one in three adults (35 percent) has obesity. Before 2013, no state had an adult obesity prevalence at or above 35 percent. Currently, at least one in five adults (20 percent) in each U.S. state is living with obesity.

Four human cases of highly pathogenic avian influenza (HPAI) A(H5) (“H5 bird flu”) virus infection in the state of Colorado have been confirmed by the Centers for Disease Control and Prevention (CDC).

Following years of declines in measles vaccination coverage, measles cases in 2022 have increased by 18 percent, and deaths have increased by 43 percent globally (compared to 2021). This takes the estimated number of measles cases to 9 million and deaths to 136,000 – mostly among children – according to a new report from the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC).
