Overview
- Uruguay confirmed four measles infections by IgM/IgG testing in three adults (46, 39, 21) and one 11-year-old child, all unvaccinated and part of the same family.
- The travelers entered via Yacuiba–Salvador Mazza and exited at Colón–Paysandú between Nov. 13–16, riding long‑distance buses operated by Autobuses Quirquincho, Balut Hermanos and San José with stops across multiple provinces.
- Argentina’s health ministry published detailed itineraries and asked anyone on the listed buses, terminals or paradores to watch for fever with rash, wear a mask and seek care promptly, stating seat location and travel times do not limit exposure risk.
- National and provincial teams began investigations around Nov. 21 to identify contacts and implement control measures, with jurisdictions reinforcing surveillance and public messaging.
- The four patients are clinically stable and other family members remain asymptomatic, and authorities report no confirmed onward transmission inside Argentina to date; vaccination catch‑up is urged, including additional early doses for young children in AMBA.
