Major Infectious Disease Risk Table
| Disease | Risk Period | Risk Areas | Prevention |
|---|---|---|---|
| Tick-borne encephalitis | April–October | Forests, rural areas | Vaccination recommended |
| Lyme disease | Year-round (peak spring/autumn) | Grassland, forests | Repellents, protective clothing |
| West Nile virus infection | July–October | Urban and rural areas | Mosquito prevention (repellents) |

Water and Food Safety in Czech Republic
Water Safety
Czech tap water is generally safe and drinkable in major cities including Prague. However, observe these precautions:
- Urban tap water: Drinkable, but older buildings may have pipe corrosion affecting water quality
- Rural areas and campsites: Untreated water may be used; bottled mineral water is recommended
- Hardness: Czech water tends toward hardness; sensitive individuals may experience temporary diarrhea
Recommendations: If uncertain, purchase bottled mineral water (local brands like Mattoni, Ploskovice).
Food Safety and Precautions
Czech cuisine relies on thorough cooking, resulting in relatively low food poisoning risk. However, note the following:
Safe foods
- Beef stew, pork soup, and other cooked dishes
- Bread, dairy products
- Hot coffee and tea
Higher-risk foods
- Street vendor raw vegetable salads (especially summer)
- Unpasteurized dairy products
- Wild freshwater fish
- Ham and sausages (if cold storage is inadequate)
