The health risk information presented here is summarized from Shoreland Travax®, a decision-support tool used by health care providers to perform a detailed health risk analysis based on specific locations, individual travel styles, and traveler risk behaviors. Travax provides practitioners current, independently researched malaria risk and prevention recommendations in a map-based format that goes beyond the annual WHO and CDC statements included here. Not included here are current reports from Travax of disease outbreaks or environmental events that may pose elevated risks to travelers’ health and safety. The Providers section of this site offers a directory of health care providers who utilize Shoreland Travax for travel health counseling. Learn more about the detailed reports and maps available from these practitioners (includes links to samples).
Depending on your itinerary, your personal risk factors, and the length of your visit, your health care provider may offer you vaccination against hepatitis A, hepatitis B, influenza, measles, mumps, rubella, rabies, or typhoid fever. Routine immunizations, such as those that prevent tetanus/diphtheria or "childhood" diseases, should be reviewed and updated as needed.

The following is current information as reported by the World Health Organization (WHO) and the U.S. Centers for Disease Control (CDC):
WHO—International Travel and Health (current online update, Country List)(2018) Malaria risk due almost exclusively to P. vivax exists intermittently throughout the year in some rural areas that are not often visited by tourists. Low risk exists in some localities in Chiapas State (Costa). Localities with very low risk are situated in the states of Chihuahua, Durango, Nayarit, Quintana Roo and Sinaloa.
- Recommended prevention in moderate risk areas: A – Very limited risk of malaria transmission. Mosquito bite prevention only.
WHO Country List footnote: When available, the date of the most recent update or confirmation is indicated in parentheses in the country list. If no date is indicated, the most recent update or confirmation was provided before 2013.
CDC—Health Information for International Travel (current online edition)Areas with malaria: Present in Campeche, Chiapas, Chihuahua, Nayarit, and Sinaloa. Rare cases in Durango, Jalisco, Oaxaca, Sonora, and Tabasco. Rare cases in the municipality of Othon P. Blanco in the southern part of Quintana Roo bordering Belize. No malaria along the US–Mexico border (see Map 3-32).
- Estimated relative risk of malaria for US travelers: Very Low.
- Drug resistance4: None.
- Malaria species: P. vivax 100%.
- Recommended chemoprophylaxis:
- States of Campeche, Chiapas, Chihuahua, Nayarit, and Sinaloa: Atovaquone-proguanil, chloroquine, doxycycline, mefloquine, or primaquine.5 States of Durango, Jalisco, Oaxaca, Sonora, Tabasco, and Othón P. Blanco municipality of Quintana Roo: Mosquito avoidance only.

High risk exists throughout the country, including in deluxe accommodations. Food and beverage precautions may reduce the likelihood of illness.
Travelers should carry loperamide for self-treatment of diarrhea and, if risk is moderate to high, an antibiotic to add if diarrhea is severe. Consult a knowledgeable health care provider regarding which antibiotic is appropriate for you and most effective for your destination.
Other Food-Borne Illnesses
Precautions to prevent brucellosis may be needed.

The material below includes information from the U.S. Department of State (DOS), U.K. Foreign & Commonwealth Office (FCO), Global Affairs Canada (GAC), and Australia's Department of Foreign Affairs and Trade (DFAT), as well as from additional open-source material. Standard safety precautions that apply to all international travel can be found in the Library article Safety and Security.
Consular Travel Advice
Due to ongoing violence and organized crime, U.S. (DOS) advises avoiding travel to Colima, Guerrero (including Acapulco), Michoacán, Sinaloa (except areas frequented by travelers in Mazatlán), and Tamaulipas states and advises reconsidering travel (or avoiding nonessential travel) to Chihuahua, Coahuila, Durango, Jalisco (except Guadalajara and Puerto Vallarta), México, Morelos, Nayarit, Nuevo León, San Luis Potosí, Sonora, and Zacatecas states. Canada (GAC) and Australia (DFAT) have more limited warnings. U.K. (FCO) has no current warning.
No intrinsic risk of attack by terrorist groups exists, but unforeseen attacks are possible.
High risk of violent crime (armed robbery, sexual assault, carjacking, and murder) and petty crime exists throughout most of the country, especially in Mexico City (particularly on the metro) and other cities, and resort areas. Risk of violent crime exists in areas frequented by tourists, including Acapulco, Cancún, Cabo San Lucas, Cozumel, and Playa del Carmen.
Kidnappings by criminal groups occur throughout the country, especially in northern border cities, Mexico City, and the states of Guerrero, México, and Tamaulipas.
Express kidnappings to force cash withdrawals at ATMs occur in Mexico City and other cities.
Scams involving false identity (such as criminals posing as police officers), pirated merchandise, and unethical actions by health care providers have been reported.
Risk exists of robberies and/or assaults occurring after consuming intentionally drugged food or drink; tourists are frequently targeted. Highest threat areas include resorts.
Protests and demonstrations frequently occur throughout the country, especially in Mexico City and Chiapas, Guerrero, Michoacán, and Oaxaca states, and have the potential to turn violent without warning. Bystanders are at risk of harm from violence or from the response by authorities. Disruption to transportation, free movement, or the ability to carry out daily activities may occur.
Armed conflict may occur and a dangerous security environment may exist in the northern states of Sonora, Chihuahua, Coahuila, Nuevo León, Tamaulipas, Sinaloa, Durango, and the southwestern states of Guerrero, Jalisco, Michoacán, and Nayarit.
Basic safety standards for recreational water activities (including scuba diving, snorkeling, and jet-skiing) are often not in place. Rent water sports equipment from reputable operators. Scuba dive only with personnel certified by PADI or NAUI, and use equipment only from PADI- or NAUI-certified dive operators.
High risk of traffic-related injury or death exists. The road-traffic death rate is 12 to 24 per 100,000 population. The rate is less than 10 in most high-income countries. Speed laws are poorly enforced. Seek local advice before traveling on roads outside urban areas after dark. Driving at night is not advised.
Traffic flows on the right-hand side of the road. Travelers (including drivers and pedestrians) accustomed to traffic moving on the opposite side should be vigilant when navigating traffic.
Many taxis are unsafe. Use taxis from official ranks or dispatched via smart phone app or radio from a reputable company and ascertain the license or identification number of the dispatched vehicle.
U.S. Federal Aviation Administration has determined that the civil aviation authority of this country oversees its air carriers in accordance with minimum international safety standards.
The hurricane season is from June through November in coastal areas along the Gulf of Mexico and the Pacific Ocean. Floods, mudslides, and landslides may occur.
Seismic and volcanic activity frequently occur.
