Nice is a healthy place, so your main risks are likely to be sunburn, foot blisters, insect bites, jellyfish stings and mild stomach problems from eating and drinking with too much gusto.
Checking insurance quotes…
Before You Go
No vaccinations are required to travel to France but the World Health Organization (WHO) recommends that all travellers be covered for diphtheria, tetanus, measles, mumps, rubella and polio, regardless of their destination.
Citizens of the EU, Switzerland, Iceland, Norway and Liechtenstein receive free or reduced-cost, state-provided health-care cover with the European Health Insurance Card (EHIC) for medical treatment that becomes necessary while in France. Each family member will need a separate card.
The EHIC does not cover private health care, so make sure that you are treated by a state health-care provider (conventionné). You will need to pay directly and fill in a treatment form (feuille de soins); keep the form to claim any refunds. In general, you can claim back around 70% of the standard treatment cost.
Citizens of other countries need to check if there is a reciprocal arrangement for free medical care between their country and France.
Taking out a travel health insurance policy is recommended. Some policies specifically exclude dangerous activities such as scuba diving, motorcycling, skiing and even trekking: read the fine print. Check that the policy covers ambulances or an emergency flight home. Find out in advance if your insurance plan will make payments directly to providers or reimburse you later for overseas health expenditures: if you have to claim later, make sure you keep all documentation.
Tap water is safe to drink in Nice, as it is throughout France.
Heat exhaustion follows excessive fluid loss with inadequate replacement of fluids and salt. Symptoms include headache, dizziness and tiredness. Dehydration is already happening by the time you feel thirsty – aim to drink enough water to produce pale, diluted urine. To treat heat exhaustion, replace lost fluids by drinking water and/or fruit juice, and cool the body with cold water and fans.
Purple Pelagia noctiluca jellyfish, which can deliver a painful sting, are occasionally a problem in Nice's offshore waters. The website www.riviera-beaches.com/Jellyfish.html offers helpful English-language information on how to avoid and treat jellyfish stings, and the site http://meduse.acri.fr/carte/carte.php maps current jellyfish conditions on Côte d'Azur beaches.
