Spain's tick surge sparks health warnings as infections climb in 2026

Ticks are appearing earlier and in greater numbers across Spain this year. Health officials have raised alarms about rising infections in parks and mountainous regions. Warmer weather and damp conditions have created ideal breeding grounds for these parasites. The mild winter and wet start to 2026 have extended the tick season in Spain. Forestry experts in Madrid report a noticeable increase in infected ticks, raising concerns about diseases like Lyme and Crimean-Congo haemorrhagic fever. Regional authorities in Aragon and Andalucia have also warned of unusually high tick populations in grassy and wooded areas.

Hikers, campers and dog walkers now face a higher risk of bites. Experts recommend wearing light-coloured trousers tucked into socks to spot ticks more easily. After outdoor activities, thorough checks of skin and fur are essential, as early removal reduces infection risks.

Cristina Román’s recent case highlights the challenges of diagnosing tick-borne illnesses. Her prolonged symptoms underscored how Lyme disease can go unnoticed. Health officials advise using fine-tipped tweezers to grasp ticks near the skin and pull steadily upward to remove them safely. The spread of ticks in Spain is linked to climate shifts and changing habitats. Authorities stress prevention and quick removal as key to avoiding serious illness. Public awareness campaigns are now underway to inform residents and visitors about the growing threat.
