Birth announcement during covid-19

Hi ladies, I live in Sydney Australia and due to give birth next month. We are not really under strict lockdown at the moment due to low daily covid-19 numbers. I still feel really anxious having loads of visitors over when baby is born :( What is a nice and kind birth announcement message that will help people understand they should not visit baby if they feel unwell. I don’t know how to word it. Thank you in advance ☺️
