I never realized how widespread these diseases our until my friend got sick from her fish.
It sounds weird doesn't it? I did too but apparently, fish can carry zoonotic diseases too and pass it on to humans who handle them.
What happened to my friend is that he got a fish tank in his room. Soon after he developed asthma. He used to get asthma attacks daily and kept going to the hospital. The doctors ran so many tests and didn't find anything. Finally one doctor asked about his room and when he heard that he had fish, he told my friend to take the fish tank out.
It worked! It was the fish! The doctor told him that fish carry a type of bacteria that gets into the tank water and eventually the surrounding air. That was what was causing his asthma! Unbelievable!
