There is no way to compare mold and bacteria because there are differences in the location and degree of infection between mold and bacteria, and even if the infection is in the same location, the severity may be different. Regardless of which germ infection occurs, you need to go to the hospital for relevant examination and treatment in a timely manner. Mold is a fungus, a mycobacterium composed of mycelium as the basic unit, while bacteria can be divided into cocci, bacilli, spirochetes, etc. In daily life, bacterial infections are more common. Bacterial infections are mostly manifested as fever, redness, swelling, pain, pus, etc. Lesions are usually more limited, and when upper respiratory tract infections and skin infections occur, they are generally easier to cure, usually with antibiotics or symptomatic treatment only. If the bacterial infection of the blood or organs, such as bronchitis, pneumonia, meningitis, etc., it is more serious, usually more complicated treatment process, treatment time is longer, need to use antibacterial drugs under the guidance of a doctor. Mycobacterial infection can be manifested as itching, local dryness, burning sensation, etc. The symptoms are different for different parts of the infection. Usually people with low immunity and long time use of hormones, antibiotics and other drugs are prone to mycobacterial infections. It is also complicated and requires regular follow-up visits to the hospital.
