Warning alert

Face masks to be worn in some areas of our hospitals

With rates of flu rising, we are asking staff, patients and visitors to wear the masks available in our Emergency Department as well as other areas where there is a high risk of infections spreading.  

Staff and visitors should not enter clinical areas if they have symptoms of flu, norovirus or COVID-19. Patients with symptoms who need emergency care should still attend but wear a mask if possible.

We will continue to monitor this situation to ensure we are taking the right precautions for the safety of our patients and staff. 

Visitors to other areas can wear a mask if they choose to, and masks will be available at the main entrances of our hospitals and all wards.

If you are eligible and have not already done so, please consider getting your flu vaccination to protect yourself and others.

Help us to prevent the spread of flu and other respiratory viruses, to keep our patients safe

Flu is a highly infectious and very common viral illness that is spread by coughs and sneezes. It is not the same as the common cold. Flu is caused by a different group of viruses. Symptoms tend to be more severe and last for longer. You can catch flu (short for influenza), all year round, but it is especially common in winter months in the UK.

Symptoms of flu include:

  • Fever (38 degrees C)
  • Shortness of breath or cough
  • Headache
  • Runny nose
  • Sore throat
  • Fatigue
  • Aching limbs
  • Lack of appetite
  • Vomiting and/ or diarrhoea

If you have a fever and any two of the above symptoms do not visit the hospital.

People are most infectious soon after they develop symptoms. They can continue to spread the virus in coughs and sneezes, for between five and seven days. People become less infectious as their symptoms subside and once symptoms are gone, they are no longer considered infectious to others. If you had a transplant and/or receive chemotherapy or other immunosuppression you might be excreting the virus for longer

  • The very elderly
  • Those with long-term lung, kidney, neurological, liver or heart disease;
  • Children under five and people over 65   Those with diabetes mellitus
  • People with weaken immune systems as a result of a disease (such as HIV/AIDS) or medication (such as steroids, chemotherapy)
