With COVID-19 cases surging in some parts of the world and more transmissible variants (that is, Delta, and Omicron), it is essential to remain vigilant for signs and symptoms of COVID-19, get vaccinated as soon as it is your turn and adhere to public health and social measures at all times, regardless of your vaccination status, to help prevent transmission.
This is especially important if you plan to travel over the holidays, since you may be exposed to the coronavirus while travelling. Even if you have a negative COVID-19 test before your trip, you could still be in the early incubation stage of illness, so it is important to stay vigilant.
