Well, if you took Albendazole, then you are still not better, then you dont have something like Trichuria.
More Likely you have Protozoa, if al of the family members have the same symptoms.
Can you list all your symptoms? when did they start? and what have you been eating lately? Salads? travel outside? Camping? Do you have pain? Where? How many times diarrhea? constipation? Bloating?
Clearly you got something? But we want to rule out protozoa.
