I am partially vaccinated and effected with cold and fever and typically I feel that no smell and bit taste issue may be because of cold. I haven't used any medicine apart from dolo. Fever last for 2 days only. My kid 2.5 yrs old effected with fever after a week and last for 3 days. Pediatrician said it's a flu. Though my husband is staying with us and he doesn't have any symptoms either (no cold, fever etc). How can I know that I was either effected with covid or common flu? Any blood work need to be done to know this because my second dose vaccination is due this week. Thanks
