Harbour seal (Phoca vitulina) killed by phocine distemper virus (PDV). Living seals are seen by the water. The harbour seal is the most widespread of all seals,and is found in cold and temperate waters throughout much of the northern hemisphere. In 1988,an outbreak of PDV killed around 18,000 harbour seals in European waters,over half the population in some areas. The population had recovered fully by 2002,when a second outbreak began. Thousands of seals died in this outbreak,although it is hoped that numbers will increase as they did after the 1988 epidemic. There is no cure or prevention for the disease.
