The HSE West is urging the people of Mayo, Roscommon and Galway to think carefully about the number of people they see in the run-up to Christmas Day.
Dr Breda Smyth, HSE Director of Public Health in the West has issued a statement saying that, as we approach Christmas, it's vitally important that we all limit the number of interactions we have with others.
Recent Thanksgiving celebrations in the US show that one day of mixing with older loved ones has led to increased numbers of hospitalisations and deaths, and we can prevent this by ensuring we're not carrying the virus, and have reduced our contacts in the week leading up to Christmas Day.
Dr Smyth says the more risks people take, and the more people meet can have a really significant impact on the spread of Covid-19, and we must remain vigilant to protect ourselves and our loved ones.
The HSE West has also issued guidance for Christmas Day - encouraging people to wash hands regularly, avoid hugs, kisses and handshakes and wear masks when serving and preparing food, while keeping homes ventilated.
