Entry & Exit Requirements
U.S. citizens must have a valid passport to enter Mexico. Passports must be valid for at least the duration of your stay. As this requirement is subject to change at any time without notice, we recommend at least 6 months’ validity. A passport card is not acceptable for entry to the U.S. by air.
If you are not traveling with a U.S. passport, please check with the Mexican Embassy for the requirements based on your nationality.
Health Information
Immunizations
The Centers for Disease Control recommends that all travelers be up to date on routine vaccinations such as measles-mumps-rubella (MMR) vaccine, diphtheria-pertussis-tetanus vaccine, varicella (chicken pox) vaccine, and your yearly flu shot before every trip.
There are no vaccinations required for entry into Mexico, unless you are traveling from a country where yellow fever transmission is a risk.
Though not required, the CDC recommends inoculation against hepatitis A, hepatitis B, and typhoid for most unvaccinated travelers to Mexico.
Please consult your physician for additional information and recommendations based on your individual circumstances.
Malaria
The CDC does not consider travelers to San Miguel de Allende or the Mexican states of Guanajuato and Querétaro to be at risk for malaria.
Dengue Fever and Other Insect-borne Illnesses
The CDC warns that dengue fever is a potential risk in Mexico. In addition, locally transmitted cases of Zika virus, Chagas disease, and other insect-borne illnesses have previously been reported. As there are currently no vaccines available for these illnesses, the CDC recommends that travelers take precautions to avoid insect bites. To protect against mosquitos and other biting insects, the CDC recommends that you cover exposed skin with lightweight, long-sleeved shirts and pants, consider treating clothes with permethrin, and use an insect repellent containing an EPA-registered active ingredient like DEET, picaridin, or oil of lemon eucalyptus (OLE). Apply sunscreen first, followed by the repellent, ideally 20 minutes later.
Be careful when applying products containing DEET, as it can damage or dissolve certain synthetic fabrics as well as plastic, rubber, vinyl, or elastic materials, such as those used in camera equipment, binoculars, phone cases, sunglasses, or watches. Additionally, some research suggests that when DEET and picaridin enter local waterways, they can be harmful to amphibians and other wildlife. When selecting a repellent, it is ultimately up to each traveler to weigh the risks and benefits of different options, keeping in mind both environmental factors and the importance of protecting against illness.
After spending time outdoors, especially in grassy or wooded areas, the CDC recommends showering and conducting a full-body check for ticks. If you find a tick attached to your skin, safely remove it with tweezers as soon as possible.
As a precaution, the CDC advises women who are pregnant to consider postponing travel to any area where Zika virus transmission is ongoing.
Altitude Sickness
San Miguel de Allende is located at high elevations (above 5,000 feet), so shortness of breath and a pounding heart are normal responses to the lack of oxygen in the air upon arrival. However, for some visitors, these symptoms can deteriorate into altitude sickness. Headache, extreme tiredness, dizziness, nausea, and loss of appetite are standard symptoms. Staying hydrated and well rested is important to adjust to the altitude. Avoiding heavy, fatty foods and alcohol in the days before arriving to altitude can help. Over-the-counter medications are also available to help prevent or alleviate symptoms. It’s advisable to avoid sleep medications, as they can slow breathing and respiration, which aid in getting the blood oxygenated while sleeping. Participants who take blood pressure medications should discuss this with their doctor as the medication can drop pressure too low at times.
Visit the CDC website for more information.
Travelers’ Diarrhea
The CDC warns that travelers’ diarrhea is the most common travel-related illness. Consumption of contaminated food and water may cause diarrhea. To avoid this, do not drink tap water, and use bottled water to brush your teeth. Avoid ice and uncooked vegetables or fruit without a peel. When in doubt, ask your guide. Restrict yourself to cooked food at restaurants, and avoid food sold on the streets. If you contract diarrhea, it is very important to drink large quantities of purified water. Consult your doctor for appropriate medication should you contract diarrhea.
Some people are extremely sensitive and may get diarrhea simply because of dietary changes. If you are prone to gastrointestinal issues, consult your physician or nutritionist for preventative measures.
Sun Exposure
The effects of the sun can be damaging to the eyes and skin. Spending time outdoors exposes you to the sun’s harmful ultraviolet (UV) rays, even on cloudy days. To protect yourself from the sun, use a broad spectrum sunscreen of at least SPF 15, protect skin with clothing, wear a wide-brimmed hat and sunglasses, and drink plenty of fluids.
Respiratory Illness Protocols
Please review our Respiratory Illness Protocols page, which explains our policy and procedures if you or another traveler should develop symptoms of a respiratory illness during your trip. Your participation in a Holbrook Travel program indicates that you are in agreement with these protocols.
