At the Central Middlesex hospital in the northwest London the outbreak of measles began after two children were admitted to it last week and later. One 13 year old boy from the North West has died from this disease.
Now hundreds of hospital staffs that were exposed to the hospital scenario, are being vaccinated against measles.
Six nurses contracted measles from the kids and are treated in an isolation unit at Norhtwick Park Hospital.
Hospital visitors from the past few days that are feeling feverish are advised to contact their GP.
A hospital trust is at present working with the Health Protection Agency to take all the necessary precautions.
