Monkeypox - Update and advice (11 August 2022)
Recent reports show that there continue to be confirmed cases of Monkeypox infections in the UK. While the current risk is low to the general population, we are asking patients some additional questions when booking an appointment and on arrival at the department. This will ensure we keep our patients and staff safe.
Please inform the service immediately on arrival (at the reception desk) if any of below apply to you:
- You are a man or transwoman who has sex with men and have had these symptoms in the last 3 weeks: an intense headache, muscle aches, a new rash on any part of your body, a fever, or any new lumps in your neck, groin or under your arms (swollen lymph nodes)
- You’ve been in close contact with someone who has Monkeypox in the last 3 weeks
- You have confirmed Monkeypox
- You’ve returned from West or Central Africa in the last 3 weeks and have any of the symptoms above

Person-to-person spread of monkeypox may occur through:
- Direct contact with the skin lesions or scabs.
- Contact with clothing or linens (such as bedding or towels) that have been used by an infected person
- Breathing in droplets from the coughing or sneezing of someone who has a monkeypox rash.
Monkeypox Vaccination
Please DO NOT call our booking line as they are unable to book appointments for vaccinations at this time.
We will update this information once there is further information about access to the Monkeypox vaccination. Thank you for your continued patience.

Paddington square construction works next to St Mary's Hospital
Patients and visitors to St Mary’s Hospital may experience some disruption caused by nearby construction works for the Paddington Square development (located between Praed Street and South Wharf Road). We apologise in advance for any impact these neighbouring works may have for our patients and visitors.
While the developer has put in place a range of mitigation and monitoring measures, we anticipate that there may be some disruption caused by additional noise, dust and vibration. If patients and visitors wish to raise any issues about the impact of the construction works on their care and treatment, then we would ask them to speak to our staff or contact the patient advice and liaison service (PALS).
