While remaining vigilant and prepared, it was also important not to panic about possible transmission.
"People have to be double vaccinated to travel, or have a negative test if they're unvaccinated, within three days. With these measures put in place, it reduces the chances of Covid-19 coming down into our region."
Dr Atmore said that while the region was as well-prepared as possible, "you can never be fully prepared for something that you've not had to manage before".
