Which of the following is not considered a genetic disease?

Genetic diseases are caused by abnormalities in an individual's DNA or genetic makeup, often hereditary in nature. Tay-Sachs disease, hemophilia, and cystic fibrosis are all examples of genetic disorders caused by specific mutations or inherited traits that affect the body’s function. Tay-Sachs is a fatal genetic disorder that primarily affects nerve cells in the brain, hemophilia is a genetic disorder that impairs the body’s ability to make blood clots, and cystic fibrosis is caused by a mutation in the CFTR gene, leading to severe respiratory and digestive problems.

On the other hand, influenza is an infectious disease caused by the influenza virus, which is not linked to genetic mutations or hereditary factors. Influenza can spread from person to person and is treated as a viral infection, thus placing it outside the category of genetic diseases. This distinction is critical in understanding the difference between inherited conditions and those caused by environmental pathogens.
