The Irish Health and Safety Executive has issued a warning to health workers in Dublin and County Meath following an outbreak of Measles in the area, with seven cases reported since 19 October 2017. Measles is a Viral Disease, that presents as a fever combined with a cough and inflamed eyes, followed by the development of a rash first in the mouth and then across the body. About 30% of cases go on to develop complications, which can include diarrhoea, blindness, inflammation of the brain and pneumonia, and the disease can be fatal. Measles is a highly infectious airborne disease spread by coughing, with un-immunised people living in close proximity to infected persons having an approximately 90% chance of catching the Virus. The disease is easily prevented by vaccination, but hard to treat once people are infected, with small children, who are least likely to have been immunised, particularly vulnerable. This makes it particularly important for health workers to be alert for new cases once the disease becomes established in an area, and ensure that all potential cases are screened for the Virus promptly.

Measles is caused by a single-strand RNA Virus belonging to the genus Morbillivirus, which also includes the Viruses that cause Canine Distemper and Rinderpest, as well as a variety of other diseases infecting domestic and wild Mammals. The genius Morbillivirus is in turn a member of the Paramyxoviridae, a group of Viruses that infect a wide range of Mammals, Birds, Reptiles and Fish, and includes the Virus that causes Mumps in Humans.
