Suggestion needed. Lung infection?

Background:5 years back my mother was diagnosed by TB and she had taken 6 months course and it got cured. 15 days back my father was having fever for a week with backpain and covid test(rapid antigen) result was shown as negative.. as per doctor recommendations he still took covid treatment at home and got recovered. My mother also started developing symptoms 5 days back. It started with headache and then slight cough for a day. Fever continued for 3 days and from last 2 days she doesn't have any symptoms other than weekness. Since she had TB earlier(5 years back), do we need to go for any scanning at this time or we need to follow any medication as precautionary to clear any possible lung infection ?
