UTI is not a nationally recognized infectious disease, but it is contagious because it is caused by a pathogen.
Infectious diseases are diseases that can spread from person to person, from person to animal and are widely prevalent, either by direct contact with an infected person or through air, water, food, etc. UTI is caused by infection with various pathogens.
UTI is a urethral infection caused by a variety of pathogens, which does not cause widespread epidemics, does not have the characteristics of infectious diseases, and does not belong to infectious diseases.
Pathogens that cause urethritis include Escherichia coli, Streptococcus, Staphylococcus, Chlamydia trachomatis, Mycoplasma, Neisseria gonorrhea, etc. They can be transmitted through sexual contact, and are therefore contagious.
Urethritis can manifest as redness and swelling of the urethral opening, urethral itching, painful urination, urethral discharge and other symptoms, which should be treated under the guidance of a doctor for the infecting pathogen.
