Bites and stings
Mosquitoes are sometimes a problem, and since no good topical repellents are available locally, you should bring your own. At night, mozzies are deterred with locally sold incense coils (spiral tütsü) or an Esem Mat, a small, electrified tray that slowly vaporizes an odourless disc. Hotels and pansiyons in heavily infested areas often have mosquito screens on the windows.
Jellyfish are an occasional hazard along the Aegean shore, and they are ubiquitous in the Bosphorus and Sea of Marmara (though they aren’t such a problem around the Princes’ Islands). Sea urchins, whose spines easily detach if trodden on, are more common; the splinters must be removed to prevent infection. Snakes and scorpions can lurk among the stones at archaeological sites, and in nooks and crannies of ground-floor accommodations. There are two kinds of vipers (engerek in Turkish): the deadly, metre-long Ottoman viper, fortunately rare, and the smaller, more common and less dangerous asp viper. Neither is particularly aggressive unless disturbed; both are most commonly seen during mild spring days.
Certain ticks in Turkey carry the Crimean–Congo haemorrhagic fever (CCHF) virus, with hundreds of cases (and fatalities in two figures) annually, though the danger seems confined to rural areas of several provinces between Ankara and the Black Sea.
Although rare (one to two cases per year), rabies is another potential danger. Be wary of any animal that bites, scratches or licks you, particularly if it’s behaving erratically. If you do suspect you have been bitten by a rabid animal, wash the wound thoroughly (preferably with iodine) and seek medical attention immediately. Turkish cities are full of stray cats and dogs; dogs with a tag in their ear have been inoculated against rabies and other diseases and put back on the street with the blessing of the local authority.
