Travel vaccinations for Mexico

Hepatitis A is a viral infection transmitted through contaminated food and water or by direct contact with an infectious person. Symptoms are often mild or absent in young children, but the disease can be more serious with advancing age. Recovery can vary from weeks to months. Following hepatitis A infection immunity is lifelong. All travellers should take care with personal, food and water hygiene. As hepatitis A vaccine is well tolerated and affords long-lasting protection, it is recommended for all previously unvaccinated travellers.

Tetanus is caused by a toxin released from Clostridium tetani bacteria and occurs worldwide. Tetanus bacteria are present in soil and manure and may be introduced through open wounds such as a puncture wound, burn or scratch. Travellers should thoroughly clean all wounds and seek medical attention for injuries such as animal bites/scratches, burns or wounds contaminated with soil. Travellers should have completed a tetanus vaccination course according to the UK schedule. If travelling to a country or area where medical facilities may be limited, a booster dose of a tetanus-containing vaccine is recommended if the last dose was more than ten years ago even if five doses of vaccine have been given previously. Country-specific information on medical facilities may be found in the 'health' section of the FCDO foreign travel advice pages.

Typhoid is a bacterial infection transmitted through contaminated food and water. Previous typhoid illness may only partially protect against re-infection. Vaccination is recommended for most travellers, particularly travellers visiting friends and relatives, those in contact with an infected person, young children, frequent or long-stay travellers visiting areas where sanitation and food hygiene are likely to be poor, and laboratory personnel who may handle the bacteria for their work. All travellers should take care with personal, food and water hygiene. Oral and injectable typhoid vaccinations are available.

Chikungunya is a viral infection spread by mosquitoes which bite mainly during daytime hours. It causes a flu-like illness and can cause severe joint and muscles pains which usually improve in 1–2 weeks but may persist for months or years. It is rarely fatal. There is a risk of chikungunya in this country.Information on current outbreaks, where available, will be reported on our outbreak surveillance database. Travellers should avoid mosquito bites, particularly during daytime hours. Vaccination may be considered for individuals aged 12 years of age and over who are: travelling to regions with a current chikungunya outbreak long-term or frequent travellers to regions with an increased risk of chikungunya exposed to the chikungunya virus through their work, such as laboratory staff working with the virus Detailed advice about the use and contraindications of the available vaccines will be available in the green book chikungunya chapter in the coming months. For now, please see our chikungunya in brief page for details.

Dengue is a viral infection spread by mosquitoes which mainly feed during daytime hours. It causes a flu-like illness, which can occasionally develop into a more serious life-threatening illness. Severe dengue is rare in travellers. The mosquitoes that spread dengue are more common in towns, cities and surrounding areas. There is a risk of dengue in this country.Information on current outbreaks, where available, will be reported on our outbreak surveillance database. Travellers should avoid mosquito bites, particularly during daytime hours. Vaccination can be considered for individuals aged 4 years of age and older who have had dengue infection in the past and who are: travelling to areas where there is a risk of dengue infection or areas with an ongoing outbreak of dengue, or are exposed to dengue virus through their work, such as laboratory staff working with the virus Exceptionally, vaccination can be considered in those who have not had dengue in the past. In these situations, further expert advice should be considered. Detailed guidance on how to ascertain previous infection is available in the UK Health Security Agency Immunisation against infectious disease the 'Green book'. The final decision on vaccination rests with the health professional and the traveller after a detailed risk assessment has been performed and the potential risks of vaccination explained.

Measles is a highly infectious viral illness, spread by airborne or droplet (coughing, sneezing, drops from mouth/nose) transmission. Measles usually starts with cold-like symptoms e.g. fever, cough, runny nose and conjunctivitis (sore, red eyes). This is followed by a blotchy rash starting on the face/head and spreading to the rest of the body. Complications of measles infection can include ear infections, diarrhoea, pneumonia and convulsions (fits). Life-threatening complications such as encephalitis (brain inflammation) can occur on rare occasions. Measles can have serious consequences especially in children under 1 year of age, immunosuppressed individuals (those with a weakened immune system) and during pregnancy. Measles is either 'endemic' (continuous transmission in a 12-month period) and/or the measles risk is assessed to be greater than in the UK due to current outbreaks, conflict, damaged infrastructure, travel-related cases or poor vaccine coverage. All travellers should follow good respiratory hygiene rules and avoid contact with individuals with measles infection. All travellers should make sure they are up to date with the measles, mumps and rubella (MMR) or measles, mumps, rubella and chickenpox (MMRV) vaccines, according to current UK recommendations. Guidance on vaccinating adults can be found in Measles: the green book chapter – GOV.UK.Consider early Measles Mumps Rubella (MMR)/Measles Mumps Rubella Varicella (MMRV) vaccination for infants and children. Infants from six months of age who are likely to be mixing with local people, should receive a MMR vaccine. The MMRV vaccine can be given from nine months of age if MMR is not available at the time of the appointment. Not all children will respond to MMR/MMRV given in the first year of life. When the vaccine has been given before one year of age this dose should be discounted and two further doses of MMR/MMRV should be given at the recommended ages. Children who are travelling and have already received one dose of MMR/MMRV at the routine age should have the second dose brought forward to at least one month after the first. If a child is given the second dose less than three months after the first dose and is less than 18 months of age, then the routine 18-month dose (which would constitute a third dose) should be given in order to provide optimum protection.

Rabies is a viral infection which is usually transmitted following contact with the saliva of an infected animal most often via a bite, scratch or lick to an open wound or mucous membrane (such as on the eye, nose or mouth). Although many different animals can transmit the virus, most cases follow a bite or scratch from an infected dog. In some parts of the world, bats are an important source of infection. Rabies symptoms can take some time to develop, but when they do, the condition is almost always fatal. The risk of exposure is increased by certain activities and length of stay (see below). Children are at increased risk as they are less likely to avoid contact with animals and to report a bite, scratch or lick. Rabies is considered a risk and has been reported in domestic animals in this country. Bats may also carry rabies-like viruses. Travellers should avoid contact with all animals. Rabies is preventable with prompt post-exposure treatment. Following a possible exposure, wounds should be thoroughly cleansed and an urgent local medical assessment sought, even if the wound appears trivial. Post-exposure treatment and advice should be in accordance with national guidelines. A full course of pre-exposure vaccines simplifies and shortens the course of post-exposure treatment and removes the need for rabies immunoglobulin which is in short supply world-wide. Pre-exposure vaccinations are recommended for travellers whose activities put them at increased risk including: those at risk due to their work (e.g. laboratory staff working with the virus, those working with animals or health workers who may be caring for infected patients). those travelling to areas where access to post-exposure treatment and medical care is limited. those planning higher risk activities such as running or cycling. long-stay travellers (more than one month).
