A team of eight professionals, including doctors, nurses, and administrative staff, works in Lleida to protect the health of those traveling to international destinations with greater dangers. The main objective is to provide a comprehensive assessment of each traveler's health status and offer the necessary vaccinations or treatments, tailored to their clinical history, destination, duration, and type of trip. The season of the year is also considered, as health conditions can vary significantly.

Malaria is one of the diseases that receives the most attention, with between 10 and 30 annual cases detected in Lleida, and a notable increase since 2022. Professionals emphasize the importance of pre-travel consultation to avoid serious complications. Malaria symptoms can appear up to two weeks after a mosquito bite, so vigilance upon return is recommended.

In addition to malaria, yellow fever is warned about, present in Colombia and many South American and African countries, although not in Southeast Asia. The center stays constantly updated on global health alerts, as each country presents specific risks and there are diseases with geographical expansion, such as dengue, of which autochthonous cases have been registered in Catalonia since 2024. For long stays in Central Europe with contact with nature, the vaccine against Central European encephalitis is recommended due to the presence of ticks.

The center also emphasizes the importance of keeping up-to-date with routine vaccination schedules, expressing concern about measles, as Spain lost its measles-free status four months ago. Last year, more than 3,700 people visited the Lleida International Vaccination Center. The most common profiles are Sub-Saharan workers returning to their home countries for long periods and tourists traveling to destinations such as Thailand, Bali, or the Caribbean. It is recommended to make the first visit at least one and a half months before the trip, as some vaccines do not have an immediate effect.
