Yes it is possible with repeated long term interaction with street animals to develop certain parasitic diseases that can affect the liver
. These can be generally asymptomatic or may present with only low grade fever
or mild abdominal discomfort.
However these are unlikely to present with repeated attacks of flu
as in your case. I suggest you meet a physician in view of the repeated attacks of flu.
Also I think you should get an Ultrasound
of the abdomen. Depending on the results any further investigations may be ordered.
Hope I have answered your query you remain well. I will be available in case of any further queries.
