Deep fungal disease is a chronic disease and the source of the disease is often in the external environment such as: leaves, soil,... They penetrate through the skin and respiratory tract, patients often have lesions in the skin, mucous membranes, subcutaneous tissue, bones, joints, nerves and other organs.

Invasive fungal infections can be itchy and uncomfortable, but they are rarely serious. Common infections such as athlete's foot and ringworm are caused by fungi and are easy to get. In healthy people, the fungus usually does not spread beyond the surface of the skin, so it is easy to treat.

People living with HIV/AIDS have many opportunities for a healthy life. However, they may have some health challenges, such as avoiding infections. HIV/AIDS patients have a weakened immune system, which increases the risk of fungal infections (opportunistic infections).

Anyone can get a fungal infection, even if they are healthy. Fungi are common in the environment and people breathe in or come into contact with fungal spores every day without getting sick. However, in people with weakened immune systems, these fungi can cause infections.
