After catching covid, my daughter always gets sick from the flu very other week. what can i do to help her? should i give her some multivitamin? does she need antibiotics of some sort?

Let her pediatrician know so that she gets diagnosed and treated promptly. There is high viral activity in schools as expected and this scenario is common for the majority of kids unfortunately.

The infections may be associated with lung inflammation. Watch for signs of shortness of breath, prolonged cough and fever. Tamiflu is often effective if administered early in the course. Drink fluids,rest and a virtual consult with Healthtap is available by
