What the disease sub-score covers
Peru’s disease sub-score is 76/100 (low band). It combines endemic baseline (the diseases that are always present at some level) with acute outbreak signals from WHO Disease Outbreak News, CDC traveller notices, and ECDC bulletins. A drop in the sub-score typically reflects a fresh outbreak rather than a worsening baseline; the events feed above lists what is driving today’s number. Endemic risk is what your vaccinations and basic hygiene protect against; outbreak risk is what determines whether the trip itself should be reconsidered.
Food, water, and mosquitoes
The three traveller-illness vectors that account for most self-reported sickness: contaminated water (tap, ice cubes, salad washed in tap), undercooked food (especially shellfish and street meat), and mosquito-borne disease (dengue, chikungunya, malaria, Zika). The defensive rules are well established: bottled or filtered water only in higher-risk destinations, cooked food served hot, peel fruit yourself, and use DEET- or picaridin-based repellent in dengue-active areas at dawn and dusk. The Peru vaccinations page lists which immunisations specifically reduce risk for this country.
If an outbreak is in the news
A new WHO Disease Outbreak News article triggers a drop in the sub-score within 24 hours of publication; the events feed shows the source. Read the WHO article rather than secondary coverage: outbreak severity often gets amplified in travel press relative to the agency’s actual assessment. The Field Manual guide When an outbreak hits a destination you’ve booked walks through the decision tree: when to cancel, when to push, when to alter the itinerary.

Long-form context
Peru is broadly safe for travellers on the standard tourist circuit (Lima coastal districts, Cusco and the Sacred Valley, Machu Picchu, the Inca and Salkantay treks, Arequipa, Colca Canyon, Puno and Lake Titicaca, the northern beaches, the Amazon at Iquitos and Puerto Maldonado) and uniformly listed at the standard tier of caution by every major foreign ministry, with partial-area warnings for the VRAEM coca-trafficking region and certain border zones. The structural risks are concentrated and addressable: Cusco-altitude acclimatisation (3,400 m, higher than Machu Picchu itself), the Lima petty-crime baseline and express-kidnap pattern, periodic political demonstrations that paralysed Cusco and Puno through 2023 and 2024, the Inca Trail permit logistics that need months of lead time, gastric and altitude considerations, and rabies and yellow fever exposure on Amazon itineraries. This guide unpacks the entry mechanics, the regional risk map, the altitude logic, the political-demonstration calendar context, the Machu Picchu access mechanics, and the practical contacts that shape a Peruvian itinerary.
Frequently asked about Peru
Are there any active disease outbreaks in Peru?
Peru's disease sub-score is 76/100. Active outbreaks are listed in the recent-signals feed above, sourced from WHO Disease Outbreak News, CDC traveller notices, and ECDC bulletins. A drop in the sub-score typically reflects a fresh outbreak rather than a worsening baseline.
What diseases are common in Peru?
Endemic disease patterns vary by region within Peru. The three traveller-illness vectors that account for most reported sickness anywhere: contaminated water, undercooked food, and mosquito-borne disease (dengue, chikungunya, malaria, Zika depending on region). The vaccinations page lists which immunisations specifically reduce risk for this country.
Is the water safe to drink in Peru?
Tap water safety varies by region and infrastructure. In most non-OECD destinations, default to bottled or filtered water for drinking, ice, and brushing teeth; salads washed in tap water carry the same risk. The country safety guide's healthcare chapter covers the specific destination assessment.
