With continued warm temperatures in our bathing waters, there is a risk of growth of vibrio bacteria that are naturally occurring, especially in seawater. To date, 18 cases of more serious vibrio infections in wounds or blood (sometimes called bath ulcer fever) have been reported during the summer. The majority of cases are over 65 years old and more men than women have fallen ill. To prevent cases of illness, bathing is not recommended if you have significant wounds, especially if you are elderly and / or have a weakened immune system.
