We've had 4 staff cases where I work, no resident cases yet. We wear ppe, are careful etc, but ultimately we're still a risk because some have children in school so they can work, travel on public transport to get to work, need to go shopping for food, attend appointments etc.
Then you have other hcps that need to visit for medical reasons, to do dressings or insulin injections every day, to administer end of life meds, to take bloods or other tests that care assistants can't perform, doctors needing to physically examine people where a video call isn't sufficient. Paramedics responding to falls etc.
Then you have things that go wrong and need fixing like boilers and washing machines and even WiFi - essential for people to keep contact with their families.
Undertakes need to attend too.
All those people visit multiple settings, as well as have lives outside work.
Clients having hospital appointments, clients being admitted from the community or hospital, clients that are unable to test, Clients that are unable to wear masks or unable to understand about hand washing and sanitising, even with assistance (one of ours hates washing her hands and short of physical force which is wrong, there's not much else we can do)
And once it's in, it's in. Many dementia sufferers wander, and will do so even if they had a 1:1 staff member, physical or pharmaceutical restraint is the only method and that's not acceptable. Even in people mildly confused it's hard for them to grasp and do what is needed.
Care homes are designed to be homes, not sterile clinical settings, that makes them harder to keep sterile.
Then with so many vulnerable people in one place, it tends to be bigger news. 30 people infected and seriously ill, or several dying in a short space of time is more noticeable than 30 infections in a wider community.
But then Boris had a go at blaming the care workers, shouldn't be surprised if the general public follow without having the first idea of what us and the residents face, while the large care companies make profit from it all. It's standard in care, blame the front staff because we don't have a voice.
