Hospital services in Watford are under “significant pressure” as doctors treat an “unprecedented” number of suspected cases of swine flu in west Hertfordshire.

Beds across the country are filling up with victims of the H1N1 virus, while official figures show more than 39 people have died from the illness since October.

Watford General Hospital, in Vicarage Road, currently has 19 patients on its wards with confirmed or suspected swine flu, with seven in intensive care.

Natalie Forrest, director of nursing at West Hertfordshire Hospitals NHS Trust, said: “The severe weather conditions over the past few weeks combined with the usual winter illnesses and the combination of long bank holidays is putting significant pressure on the trust.

“We currently have 19 patients with confirmed or suspected swine flu admitted to Watford General, seven of which are requiring intensive care. This is an increase from 5 patients last week, which is putting considerable demand on the service.

“However, the situation is being constantly assessed and patient safety remains our number one priority. Despite many hospital staff also off sick with seasonal illness, we are working incredibly hard to cope with the unprecedented demand and to help ensure everyone gets the right help they need.”
