Reviewed by Alexander Webber, Chief Epidemiologist · Updated 2026-08

Portugal is a low-risk destination with high-quality healthcare infrastructure and food safety standards. Travelers should be aware of some emerging health considerations: locally acquired dengue cases have been reported in Madeira, and extreme heat events are increasingly common in summer, posing risk of heat-related illness. Routine vaccinations should be up to date, and UV radiation along the Algarve coast is high from spring through autumn.

Key Health Tips for Portugal

  • Dengue cases have been reported in Madeira from locally established Aedes aegypti mosquitoes. Use insect repellent especially in urban areas of Funchal during warmer months.
  • Heat-related illness is a real risk in summer, particularly in the Alentejo and Algarve regions where temperatures regularly exceed 40 degrees Celsius. Stay hydrated and avoid midday sun.
  • Apply SPF 30 or higher sunscreen and reapply frequently. Portugal receives high UV index levels from April through September.
  • Tick-borne encephalitis and Lyme disease occur in rural and forested areas in northern Portugal; use repellent and check for ticks after hiking.
