Health in Monterrey: air pollution, ticks and reference hospitals

Travelling to Monterrey as a couple does not require special vaccines in itself, but three things flagged by official sources are worth knowing: air pollution, a tick notice and private healthcare. This guide summarises the recommendations of Spain's Ministry of Foreign Affairs, the CDC health page (reviewed 3 September 2026) and the British FCDO health page, consulted in November 2026. It is not medical advice: see a travel-medicine service a few weeks before you go.

Air quality

Spain says Monterrey frequently has high levels of air pollution. If either of you has asthma or other respiratory problems, talk to your doctor, bring your usual medication and, on bad air days, cut back on outdoor exercise.

Ticks and spotted fever

The CDC published a notice on 23 December 2025 about cases of Rocky Mountain spotted fever, with illness and deaths, in northern Mexico along the US border, including Baja California, Sonora, Chihuahua, Coahuila and Nuevo León. If you hike, for example in the nature parks near the city, cover your skin, use an approved repellent and check clothes and body when you return. Any fever during the trip or in the following year needs medical attention, and you should say you have been in Mexico.

Vaccines and other notices

The CDC recommends being up to date with routine vaccines, including MMR, and recommends hepatitis A for unvaccinated travellers aged 1 and over, hepatitis B for those under 60 and typhoid for most travellers. It also lists the mpox vaccine among its recommendations for adults who expect new sexual partners. On food and water, the FCDO advises drinking only boiled or bottled water and avoiding ice in drinks.

Hospitals and insurance

Spain names Christus Muguerza, San José, OCA and Zambrano as reference hospitals in Monterrey. There is no social security agreement with Spain, so it recommends comprehensive medical insurance with repatriation, and private care usually asks for a deposit upfront. The FCDO adds that not all hospitals deal directly with insurers and you may have to pay and claim later. In an emergency, dial 911. And if you plan to meet new partners, agree on protection beforehand and talk to your doctor about regular STI testing.
