Measles cases continue to accumulate in the United States in what is already the second-worst year since the disease was declared eliminated a quarter-century ago.

The measles outbreak has surpassed 1,000 cases, the Centers for Disease Control and Prevention confirmed Friday, a grim milestone that has only been achieved twice in the last 30 years. Three people have died in the outbreak, according to the CDC, including two school-aged children in Texas. Children under 5 account for roughly one-third of the 1,001 cases, the majority of which have been recorded in Texas. Nearly all patients — 96 percent — were unvaccinated or had an unknown vaccination status. (Gardner, 5/9)

Enterovirus D68 (EV-D68) can cause severe acute respiratory illness (ARI) in otherwise healthy children of all ages, with hospitalized children who have an underlying condition other than asthma or who have reactive airway disease (RAD) at higher risk for poor outcomes, finds a study published yesterday in JAMA Network Open. A team led by researchers from the US Centers for Disease Control and Prevention (CDC) mined data from the New Vaccine Surveillance Network, a system based in emergency departments (EDs) and hospitals at seven US pediatric medical centers. (Van Beusekom, 5/9)

The United States will suspend Mexican exports of live cattle for 15 days to review the joint strategy in the fight against the screwworm, Mexico’s Agriculture Secretary Julio Berdegué said on social media Sunday. Berdegué said on social platform X that he had spoken with his U.S. counterpart, Brooke Rollins, who had informed him of the decision. “We don’t agree with this measure, but we’re confident we’ll reach an agreement sooner rather than later,” Berdegué said.
