Mexico contains measles outbreak with 8.8 million vaccines

The national immunization strategy has succeeded in interrupting community transmission, with active pockets now limited to seven states.

National Measles Containment Strategy

The Secretary of Health (Ssa) of Mexico has executed a mass immunization strategy as the central axis for containing an active measles outbreak in the national territory. According to the official report, from February to date, 8 million 872 thousand 358 doses of biologicals have been administered, specifically the triple viral vaccine (SRP), which protects against measles, rubella and mumps, and the double viral (SR) vaccine, for measles and rubella. This public health intervention represents a large-scale logistical and epidemiological effort aimed at establishing an immunological barrier in the population.

To support this campaign, the federal agency made a strategic acquisition of 4.5 million doses of SRP and 1.4 million of SR. A fundamental decision within the containment protocol was the expansion of the target age group, extending vaccination to people up to 49 years of age. This measure seeks to close possible immunity gaps in young adults. The operational tactic has prioritized highly mobile and vulnerable groups, with a particular focus on agricultural laborers, whose dynamics of movement between communities and crop fields in various regions make them a key population for the potential spread of the virus.

Current Epidemiological Overview and Intervention Effectiveness

The assessment of the epidemiological situation reveals that the early response and the containment measures implemented have yielded tangible results. The Ssa has highlighted that it has managed to maintain a low mortality rate in the face of the outbreak. The accumulated data, up to the date of the report, places confirmed cases of the disease at 5,029. The analysis of the geographical distribution of the incidence shows a significant concentration in the state of Chihuahua, which contributes 88 percent of the national total of infections, indicating a main epidemic focus in said entity.

A crucial indicator of the campaign’s success is the interruption of the chain of sustained community transmission at the national level. This epidemiological achievement means that the virus is no longer spreading freely in most of the country. Currently, the active circulation of the pathogen is limited to seven federal entities: Chihuahua, Guerrero, Jalisco, State of Mexico, Michoacán, Querétaro and Sinaloa. This targeting allows surveillance and vaccination resources and efforts to be directed more efficiently towards these specific regions.

Methodology and Perspectives of the Immunization Campaign

The methodology applied by the Ssa is characterized by phased planning and expansive coverage. The implementation of the vaccination strategy is not only based on the acquisition of millions of doses, but also on logistics that guarantee its application in the highest risk areas. Expanding coverage to broader age groups is an evidence-based public health measure designed to maximize population protection and eradicate potential reservoirs of the virus in vulnerable communities.

Immunization is consolidated as the most effective tool in the fight against measles and is a fundamental pillar for guaranteeing public health in Mexico. The continuity of these efforts by health authorities is imperative to consolidate progress, ensure that the population maintains an adequate protection status and move towards the total elimination of endemic transmission of the virus in the country. Active epidemiological surveillance and the sustainability of the vaccination program will be decisive for the final result.

FDA recognizes false positive in Taylor Farms lettuce

Cofepris analysis rules out contamination; FDA admits error in initial sample.

Analysis results

The Ministry of Health reported that tests carried out on lettuce and water samples from the Taylor Farms Mexico plant were negative for the parasite Cyclospora cayetanensis —which causes severe diarrhea— and also for fecal coliforms. The analyses, carried out by Cofepris, confirmed that the product complies with the physicochemical parameters established in national standards.

Traceability and false positive

Taylor Farms has a traceability system that allowed United States authorities to identify the origin of the product and track a batch held at customs in Laredo, Texas. That batch never entered US territory.

The sample obtained from that batch returned a false positive, a situation that the United States Food and Drug Administration (FDA) recognized in an update published on July 19. The Ministry of Health emphasized that the product is suitable for human consumption.

UIF identifies 55 people in the CJNG financial network

The FIU detected 55 people linked to a CJNG financial network, including 16 front companies.

The Financial Intelligence Unit (UIF) of Mexico detected 55 people allegedly linked to a financial network of the Jalisco New Generation Cartel (CJNG). The finding was achieved through specific financial indicators, as reported by the Ministry of Finance and Public Credit (SHCP).

Release 61 details that the Office of Foreign Assets Control (OFAC) of the United States Department of the Treasury designated 55 people – 39 individuals and 16 legal entities – related to this structure. The action is part of bilateral cooperation against the finances of organized crime.

Indicators detected

The FIU identified “indicators related to possible operations with resources of illicit origin.” Among them: cash operations, acquisition of high-end vehicles, jewelry and real estate, international transfers, intensive use of credit and service cards, and inconsistencies in income reported to the SAT.

The authorities detected “possible inconsistencies between the income reported to the tax authority and the resources observed in the financial system,” which strengthened the identification of the network.

Front companies and complaints

Of the total, 16 legal entities had illegal activities. According to the FIU, some registered relevant operations, while others were front companies with “limited or no apparent economic activity.”

The UIF filed a complaint with the Attorney General’s Office (FGR) for the crime of operations with resources of illicit origin. It also included the subjects designated by OFAC on the List of Blocked Persons (LPB), and added eight additional ones—four individuals and four legal entities—linked to the same financial structure.

International coordination

The Treasury stressed that the coordinated actions with the United States seek to “prevent improper use of the financial system, combat money laundering and weaken the economic structures of organized crime.” The FIU maintains cooperation with national and international authorities, in accordance with the standards of the Financial Action Task Force (FATF).

US Treasury locates Florence as a drug production center

The Treasury Department identified the Zacatecas municipality as the CJNG base for fentanyl and cocaine.

The United States Department of the Treasury identified Florencia de Benito Juárez, Zacatecas, as one of the key points of the Jalisco New Generation Cartel (CJNG) to manufacture fentanyl, cocaine and methamphetamine.

According to the agency, José Octaviano García Martínez is the current head of the plaza in the area, accompanied by Cuauhtémoc Rivera Zepeda and Uriel Hernández Morales. These last two would be in charge of the clandestine laboratories in Zacatecas and Jalisco. All three report to Audias Flores Silva—alias El Jardinero—, designated as successor to the late leader Nemesio Oseguera Cervantes, El Mencho.

Criminal presence in a small municipality

Florencia de Benito Juárez barely covers 328 square kilometers in the south of the state, in the Sierra Madre Occidental, adjacent to Jalisco. Despite its size, the municipality has been the scene of organized crime operations.

In March 2025, authorities dismantled a camp used by a criminal cell. Months later, in June, they destroyed a greenhouse used for growing marijuana. Both operations sought to neutralize illegal infrastructure.

The municipal president elected in 2024 is Fortino Cortés Ramírez, who will conclude his term in 2027.

Recent violence and federal response

On Saturday, July 18, 2025, 10 bodies were found in the municipalities of Morelos, Pánuco and Sain Alto. Of the victims, six were construction, mining and entertainment businessmen. Two others were officials of the Fresnillo city council: Fidel Alvarado de la Torre, secretary of Municipal Social Development, and firefighter Jesús Gerardo Muñetón Hernández.

Given these events, the Secretariat of National Defense deployed 100 Special Forces elements on July 22. They joined the 400 Army and National Guard troops who had already been operating since July 19. They carry out ground reconnaissance and deterrent actions in Zacatecas, Guadalupe and Fresnillo.

The conflict in the region is not new. On May 20, 2011, a clash between rival groups—known as The Florence War—left 77 people dead. The journalist Alfredo Valadez Rodríguez documented this episode in the book of the same name, published by Ediciones Proceso in 2021.
