According to the most recent Daily Report on Measles in Mexico, prepared by the General Directorate of Epidemiology and dated May 8, children between one and four years old are the group most affected by the virus.

The report also places Jalisco and Mexico City, two of the three World Cup host cities in the country, among the five states with the most infections and deaths since the outbreak began. Jalisco leads the national list with 6,756 confirmed cases and five deaths, while the nation's capital has 954 cases and three deaths.

Nuevo León, the third Mexican host city for the World Cup, ranks 17th out of the 32 states, with 70 confirmed cases and no reported deaths so far.

By age group, the highest number of accumulated cases corresponds to children aged one to four, with 2,230 infections. This is followed by people aged 25 to 29, with 1,976 cases, and the 5-to-9-year-old group, with 1,971 infections.

The 40 measles deaths are distributed across 11 states. Chihuahua has the highest number, with 21 deaths; followed by Jalisco, with five; Mexico City, with three; and Zacatecas and Durango, with two each. as well as Chiapas, Guerrero, Michoacán, Sinaloa, Sonora, and Tlaxcala, with one death per state.

Amid the outbreak, the Ministry of Health reported that during the first week of the 2026 National Vaccination Campaign, held from April 25 to May 8, 3,778,056 doses were administered nationwide.

The agency detailed that during this campaign, vaccines from the basic and complementary immunization schedules are being administered, including those for measles and rubella, measles, rubella, and mumps, tetanus, pneumococcal disease, hepatitis B, and the Respiratory Syncytial Virus (RSV) vaccine, which is given to pregnant women.

The campaign prioritizes children, adolescents, and at-risk groups as part of the efforts to strengthen the population's protection against vaccine-preventable diseases.

Mexico faces a sharp resurgence of measles: infections increase 272% in one year
Mexico has accumulated 12,154 cases of measles and 17 deaths in 2026. Jalisco accounts for 54% of infections while specialists analyze the impact of the World Cup.
Regina Orozco · 6 hours ago

Mexico is facing one of the largest measles outbreaks in recent years. As of July 10, 2026, the country has accumulated 12,154 confirmed cases and 17 deaths, figures that represent an increase of 272.7% compared to the same period in 2025, when 3,261 infections and nine deaths had been recorded, according to the Daily Measles Outbreak Report from the Ministry of Health.

The increase is occurring in a particular context: the celebration of the 2026 FIFA World Cup, which attracted thousands of national and international visitors to various Mexican venues, especially Jalisco, the state that currently has the highest number of infections in the country.

Although health authorities are maintaining constant monitoring, specialists warn that it is still too early to establish a direct link between the World Cup matches and a potential increase in infections.

Jalisco, the main epicenter of the outbreak

During 2026, Jalisco became the state with the highest transmission of measles, surpassing Chihuahua, where the national outbreak began in February 2025.

As of July 10, the state reported 6,580 confirmed cases, equivalent to 54% of the national total, in addition to an incidence rate of 73.26 cases per 100,000 inhabitants and three deaths.

Far behind are:

Mexico City: 1,004 cases.

Chiapas: 845 cases.

The concentration of infections in Jalisco is especially significant because it hosted four World Cup matches, in addition to receiving thousands of fans from various countries, including South Korea, Colombia, Uruguay, and Spain.
Experts urge caution before linking the World Cup to new infections.

Mauricio Rodríguez, Professor of Microbiology at the UNAM Faculty of Medicine and spokesperson for the University Program for Research on Epidemiological and Emerging Risks, explained that there is still insufficient evidence to conclude that the mass gatherings related to the World Cup have caused new chains of transmission.

The specialist indicated that epidemiological surveillance will be conducted in the coming weeks to identify any infections associated with the national and international travel during the sporting event.

Experts remind us that the incubation period for measles can vary between seven and 21 days, so any increase related to mass gatherings could be reflected later in official reports. The outbreak has spread throughout the country.

The spread of measles in recent months reflects a significant expansion.

While as of July 10, 2025, cases were distributed across 20 states and 79 municipalities, currently all 32 states have reported infections, with cases now present in 502 municipalities.

This trend demonstrates greater circulation of the virus across virtually the entire country, which has necessitated strengthening epidemiological surveillance and vaccination efforts.
Vaccination campaign continues.

In response to the increase in cases, the Ministry of Health has maintained an intensive vaccination campaign since February, primarily targeting:

Children.
People under 49 years of age who have not completed their vaccination schedule.

People who do not know if they have been immunized.

Authorities reiterate that the MMR (measles, mumps, rubella) vaccine remains the most effective tool for preventing complications and reducing community transmission. Fatality Rate Decreases Despite Increased Cases

Although the number of infections nearly quadrupled compared to the previous year, the fatality rate showed a reduction.

In 2025, it stood at 0.28%, while during the same period in 2026, it dropped to 0.14%.

Experts believe this trend may be related to earlier detection of cases, higher vaccination coverage, and faster access to health services. However, they emphasize that measles remains a highly contagious disease that can cause serious complications, especially in children and people with compromised immune systems.
Epidemiological Surveillance Will Continue in the Coming Weeks

Health authorities will continue to evaluate the evolution of the outbreak to determine if the intense mobility observed during the World Cup had any impact on virus transmission.

Meanwhile, experts recommend checking vaccination records and visiting health centers if symptoms consistent with measles appear.​

Mexico Faces Severe Measles Surge as Reported Cases Double
August 9, 2026

Mexico is confronting a mounting public health challenge as measles infections continue to spread nationwide. Recent data from the Pan American Health Organization (PAHO) reveals that the country recorded 12,255 confirmed cases between January and July 2026 alone. This figure more than doubles the total infections documented throughout the entirety of 2025, underlining a rapid acceleration in community transmission and a heightened level of risk across multiple regions.

Alongside the sharp rise in contagion, health authorities have confirmed 17 fatalities linked directly to the outbreak during this timeframe. The resurgence of the virus has intensified concerns among epidemiologists, who attribute part of the vulnerability to lingering gaps in routine childhood immunization schedules. States with lower vaccine coverage rates have experienced the most significant clusters, prompting federal and state health institutions to sound alarms and evaluate localized containment strategies.​,,
