Ongoing measles transmission driven by multiple active outbreaks across at least 47 jurisdictions continues to elevate case counts, with the CDC reporting 2,566 confirmed U.S. cases through August 13, 2026—already exceeding the full-year 2025 total of 2,289. Most cases remain outbreak-associated and concentrated among unvaccinated individuals, consistent with epidemiological patterns where measles' high basic reproduction number sustains rapid spread in susceptible communities. Recent weekly additions of nearly 100 cases, including surges in Pennsylvania and other states, reflect persistent community transmission. CDC surveillance updates, typically released weekly, will provide the authoritative case tallies used for market resolution through the end of August.
