Measles Case Detected in Nuevo León
Monterrey, NL. The State Health Secretariat of Nuevo León reported the detection of the first case of measles in an adult. The patient is a 21-year-old man from Chihuahua who arrived in Monterrey on June 17 and showed symptoms on July 2. After conducting a PCR test, it was confirmed that he carried the virus.
Following this confirmation, the health department initiated contact tracing and established a sanitary cordon to prevent further spread. Alma Rosa Marroquín, the state health secretary, stated, “We are talking about an imported case; there is no outbreak in the entity… We visited 1,020 homes across 33 blocks in the area.”
Unusual Spike in Pertussis Cases
Meanwhile, pertussis (whooping cough) has seen an unusual surge with 113 cases reported in Nuevo León from the beginning of 2025 compared to only four cases during the same period in the previous year. Nationally, there have been 1,100 cases reported so far this year.
Factors Contributing to the Resurgence of Measles and Pertussis
The resurgence of diseases like measles and pertussis can be attributed to several factors, including decreased vaccination coverage due to misinformation, accessibility issues, or reduced perception of risk. Increased mobility of people between regions or countries can also facilitate the reintroduction of previously controlled diseases, according to Doctors Hospital Auna.
Doctors Hospital Auna, located in Monterrey, participates in the Hospital Red de Vigilancia Epidemiológica, enabling constant surveillance. When a probable case is identified, notification is sent to the health secretariat, and samples are forwarded for testing according to current norms.
Rising Covid-19 Cases in the State
Nuevo León has experienced a higher number of Covid-19 cases for several weeks, with 427 confirmed cases in the state and 5,320 across the country. The increase may be linked to the circulation of new variants, though current cases are less pathogenic and part of seasonal illnesses.
Doctors Hospital Auna advises maintaining up-to-date vaccination schedules for both children and adults, particularly against preventable respiratory diseases. They emphasize the importance of herd immunity, achieved when a significant portion of the population is protected, reducing transmission risk.
Simple preventive measures like frequent handwashing, ventilating enclosed spaces, and prompt attention to respiratory symptoms are crucial in preventing infections.
