There could also be circumstances the place having a second an infection together with COVID impacts a baby’s remedy. Madhavan stated. However usually, it doesn’t change issues — as symptom management and holding youngsters hydrated and respiratory effectively are the priorities.

Which means each COVID vaccination and the yearly flu shot, Muller stated. Each might be given to youngsters age 6 months or older, and each slash the chance of extreme sickness.

Each docs burdened that the purpose is to not alarm dad and mom: The overwhelming majority of youngsters with COVID or the flu don’t land within the hospital. On the identical time, there are methods to decrease these odds.
