More than half of the beaches in the major Ukrainian port and tourist resort of Odessa on the Black Sea have been closed by local authorities as part of nationwide measure to combat the spread of cholera.
The main outbreak this summer is centred around the city of Nikolayev where last month nearly 100 people were diagnosed with the disease.
At least one person has died.
Odessa's tourist industry is already suffering from a slump as the rich head for foreign locations while even domestic resorts are beyond the reach of ordinary citizens.
Despite daily cholera warnings, those who make it to Odessa for their summer holidays are still determined to bathe in the sea. Doctors say this shows both extraordinary bravery and an ignorance of cholera. But, the tourists are determined not to have their holidays ruined.
"Of course it's frightening - you have to be careful, wash your hands before meals. not drink dirty water. Generally be alert."

After trying to survive the difficult economic situation all winter, many want to relax.
"I came here to rest and the sea is the main thing for me. Am I supposed to just sit here? What's the point of that?"

Fourteen years ago, city officials built water purification plants to cleanse sewage. But they admit that the plants are incapable of functioning to required safety standards.
Combined with unseasonably warm weather and a general decline in sanitary standards following the collapse of the Ukrainian economy, experts fear that cholera could easily spread to the city.
Fish imported from the Nikolayev region is subject to stringent tests and the sea water is tested regularly for the cholera bacillus.
According to sanitation experts, the bacillus has yet to be discovered in the waters of Odessa. They believe that if the virus were to arrive, they would flourish in the city's main beaches.
"We are isolating a bacillus similar to cholera in the water at the beaches. We believe that if this stimulus can survive in Odessa, then the classical cholera bacillus could also survive."
